SENTRIC NP Fuse Switch Disconnectors

■

Area of application

SENTRIC NP fuse switch disconnectors are switching devices for the occasional manual connection and disconnection of loads and distribution boards. They are designed to connect the specified rated nominal current (including a specified overload), to carry it and to disconnect it.

SENTRIC NP fuse switch disconnectors are used to isolate all poles of downstream electrical loads safely under load conditions.

The SENTRIC NP fuse switch disconnectors are ideally suited for surface mounting or installation in distribution boards (e.g. ALPHA, SIKUS), meter cabinets (e.g. ALPHA 400-ZS), and molded-plastic distribution panels e.g. SENTRIC HP.

The ability to mount these devices onto many different busbar systems supports a wide range of applications in the construction of control cabinets and control systems.

SENTRIC NP size NH 000 35 mm standard mounting rails and are optimized for use with other switching devices, for example, in capacitor units for the purpose of reactive-power compensation.

SENTRIC NP fuse switch disconnectors are used in combination with semiconductor protection fuses (e.g. SITOR) for the effective protection of frequency converters and soft starters.

General data

■

Design

The SENTRIC NP fuse switch disconnectors comprise a fuse base and a removable fuse carrier with an inspection and measuring function window.

Lyre-shaped contacts, arc chambers and connection pieces are integrated in the fuse base. The fuse links or isolating links are stored in the fuse carrier.

The fuse links can be replaced or changed without the need for any tools.

The three conducting paths in the fuse base as well as the fuse links in the fuse carrier are separated by partition walls that overlap when the device is opened and closed.

This strong self-protection is known as "full compartmentalization" and effectively and reliably prevents inter-phase arcing.

LV HRC fuses of sizes NH 000 to NH 3 according to IEC 60269-2-1 and DIN VDE 43620 are used in the SENTRIC NP fuse switch disconnectors. Furthermore, SITOR semiconductor protection fuses are also used.

For further details, see the operating instructions for the SENTRIC NP fuse switch disconnectors.

Auxiliary switches

The SENTRIC NP fuse switch disconnectors can be retrofitted with auxiliary switches for signaling the switch position of the fuse carrier.

One contact element (1 CO) can be mounted on size NH 000 of the SENTRIC 3NP4 fuse switch disconnector and two contact elements (1 CO) can be mounted on sizes NH 00 to NH 3.

Further variants and accessories for the SENTRIC NP fuse switch disconnectors as well as the complete SENTRIC NP series in industry-compatible design for increased technical requirements can be found in Catalog LV 30.

3NP40 10 3NP40 70 3NP52 with open fuse carrier

The SENTRIC NP fuse switch disconnectors are suitable for use in any climate and comply with the specifications of IEC 60947-1, IEC 60947-3 and DIN VDE 0660 Part 107.

The 3NP40 1 and 3NP40 7 variants are available tin-plated for use in extremely sulphurous atmospheres (available on request).

In addition, the SENTRIC 3NP5 series of fuse switch disconnectors complies with the requirements of BS 5419 and is also approved for marine applications.

All SENTRIC NP fuse switch connectors are either sealable as standard or using accessories.

1) Use only approved fuse links.

2) Corresponds to fuse sizes NH 000 (NH 00C) or NH 00 with smaller dimensions; maximum width 21 mm according to IEC 60269-2-1 and DIN VDE 43620.

Fuses and Fuse Systems

Introduction

■

Overview

Applications

Applications for fuses range from installation systems in residential buildings, non-residential buildings, trade and industry through to switchgear installations of the utilities.

Fuses protect cables and conductors against overload and short-circuit currents.

They are also suitable for protecting equipment and devices, such as

• protecting motors during temporary overloads resulting from

the operating mode

• or short-circuits that occur occasionally.

They protect people in the event of a fault against impermissible touch voltages in TN and TT networks.

They are used as back-up protection for miniature circuit-breakers and residual-current operated circuit-breakers. The high degree of discrimination guarantees optimum protection in radial and grid networks.

Fuse systems

Low-voltage fuses up to 1000 V fall into the following categories:

• Fuse systems that can be operated by non-specialists, such

as: NEOZED and DIAZED, which are designed to prevent mistakes regarding the nominal current and which provide protection against touch.

• Fuse systems that must only be operated by the specialist,

such as: LV HRC fuses which do not have to be designed to prevent mistakes regarding the nominal current and which do not need to provide protection against touch.

Sizes

The sizes of low-voltage fuses and, for example, the non-interchangeability for operation by the non-specialists are defined in DIN VDE 0636.

• NEOZED fuses are available in sizes D01, D02 and D03

• DIAZED fuses are available in sizes E 16, DII, DIII and DIV

• LV HRC fuses are available in sizes 000, 00, 0, 1, 2, 3, 4 and 4a

Operational classes

The operational classes of low-voltage fuses are defined in IEC 60269. Operational class gG is defined for cable and line protection.

According to DIN VDE 0636, cable and line protection was previously designated as gL, now gG is also applicable. During the transition period, for the sake of clarity, gL/gG is specified in the catalog.

The operational class aM for switchgear protection in the shortcircuit range is defined identically in IEC 60269 and DIN VDE 0636.

Benefits

For the 3KL switch disconnectors with fuse, a UL approval has been granted in combination with the new 3NE1 ...–2 fuse series.

■

Area of application

When SITOR semiconductor protection fuses are used in SENTRIC NP, SENTRIC KL and 3KM switch disconnectors, a partial reduction of the rated current of the fuse is necessary due to the higher power loss in comparison with LV HRC fuses for line protection. The use of SITOR semiconductor protection fuses in switch disconnectors may at times result in current values above the rated currents of the switches. These increased currents occur only when the switch is used with SITOR semiconductor protection fuses; they cannot be utilized when the switch is used with standard LV HRC fuses. Details are given in the table below.

When SITOR semiconductor protection fuses

of series 3NC24, 3NC84, 3NE33 and 3NE43 are used, the switching capacity of the switch disconnectors as specified in the catalog must not be fully utilized, as the blades of these fuses (in contrast to LV HRC line-protection fuses) are slotted. Occasional switching of currents up to the rated currents of the fuses is permissible.

Due to the

mechanical stress

on the relatively long fuse blades, 3NE41 SITOR semiconductor protection fuses should be switched only occasionally and only at zero current. If it is only

Fuses and Fuse Systems

Introduction

permissible to switch at zero current, the switch must be marked accordingly.

The use of SITOR semiconductor protection fuses rated above 63 A for overload protection is also not permitted when gR fuses (except 3NE1) are used.

The operating voltage is limited by the rated voltage of the switch disconnector or the fuses. During current-free switching, the limit value is the rated insulation voltage of the switch disconnector.

The 3NE1 “double protection fuses” can be used both as allrange fuses (gR/gS) as well as for semiconductor and line protection.

Due to the dimensions of SITOR semiconductor protection fuses, only the fuses shown in the Selection and ordering data below can be used in the SENTRIC NP, SENTRIC KL and 3KM switch disconnectors.
