Application

PBC cam-operatedpushbuttons are engineered for all heavyduty applications that require utmost reliability and the combination of single andmulti-speedperformance such as crane and mill drives.

Description

The Plungers are one-piecemolded high impact phenolic. The button surface is concave for easy thumb operation. In the assembly, the plunger is protected by steel mounting

rib sections and the recessed shape of the front cover. Plungers are mechanically interlocked.

Return Springs — Two extralong, low-stress,corrosion proof springs are provided for each plunger. They are engineered for maximum dependability, safety and ease of plunger operation.

Cam Plates are molded of selflubricating Nylatron® GS and have a series of openings to allow the movable contacts to close in sequence against the stationary contacts. Cam plates are keyed to the operating plungers. Desired operating sequences can be obtained by inserting the proper cam plate.

The Contact Blocks, to which the stationary and movable contacts and terminals are assembled, are compression molded from fiberglass polyester material. This material is highly resistant to shock, arcing and tracking.

The heavy-butt-typesilver

Stationary Contacts and terminals are riveted to the contact block.

The Movable Contact Bar with its silver contact-buttonsis fastened to the contact block

by a post and silver coated beryllium copper Contact Spring arrangement. The silver-to-silveralignment provides unusually long contact life. A slight wiping action of the movable contact promotesself-cleaningand optimum conductivity.

The contact block assembly is easily replaced as a unit.

Compact Pendant Pushbutton

Station NEMA Type 4X Enclosure

Hubbell’s Compact Pendant Stations are typically used to control industrial cranes and hoists or the remote control of industrial machines.

This high-qualitypendant station features a tough molded polymer housing that meets the most rigorous requirements of industrial applications and their environments for control of electric hoists. The compact pendant is rated NEMA 4X when used with the cord connector kit.

Safety Yellow high impact polymer enclosures.

A compact pendant station engineered to fit the hand comfortably.

Choice of single-speed,two-speed,oron-offcapabilities.

Mechanical interlock on reversing stations prevents actuating both pushbuttons simultaneously.

UL and CSA listed.

Ambient Temperature Range –20°to 158°F(–29°to 70°C)

Optional - Cord Connector Kit - to permit use in NEMA 4X watertight, dust-tight,and corrosion resistant applications or for out-

door use.

U®L

Application

Industrial plants have expanded the use of electric motor driven hoists (over the chainfall types) as the need for greater hoist capacity has increased. These electric motor hoists are an excel-

lent application for the Hubbell Compact Pendant. Especially in areas where the stations are subject to operational abuse.

Locations include jib cranes on building columns, small overhead hoists on gantry cranes, and even the operation of hoists applied to single girder cranes.

These pendant stations are designed for the comfort of the operator in controlling the hoists and built to withstand hostile environments in the industrial arena.

Most of the electric hoists have reversing electrical relays or contactors which can be controlled from a single control contact and these pendant stations are designed for those hoist applications, not for the direct power handling of the motor current in the pendant station.

Jogging operation of floormounted machines away from the main operator’s station is generally associated with only one motion, easily handled by the pendant station applied to an umbilical cord.

These stations have also been used very successfully for winch control on recreational vehicles and tow trucks and for dock control with carriers in the

food industries.

Specifications

Mini-MasterSwitch

The Euclid Mini-MasterSwitch uses a handle operated cam switch mechanism in a NEMA rated housing. It is engineered for use where master switch control is preferred, for CMAA duty overhead crane and similar applications.

Housings for surface or flush mounting.

NEMA Types 1, 3, 4 and 13.

Very compact size.

Choice of spring return vertical handle or maintained position vertical handle.

Plunger detents give operator “positive position feel.”

Heavy-duty,cam-operatedswitch units.

Up to 5–speedpoints in each direction.

Up to 16 circuits plus feed for each direction provide unlimited operation sequences.

Jam-proofmechanism for contact protection.

Application

Euclid Mini-MasterSwitches are engineered to meet the need for a small,multi-circuitmaster switch for installations such as: small crane cabs, and mill auxiliaries.

Description

The operating head is molded of tough fiberglass reinforced polyester resin. The housing is engineered for extra strength and impact resistance. The stainless steel operating rod has a 118" diameter tough plastic knob. The lever is supported

within the operating head by oil-impregnatedbushings. The operating mechanism within the head is comprised of precision machined components carefully assembled and tested to assure a long,trouble-freeservice life.

The enclosure to which the head is fastened is a dieformed metal stamping. On NEMA 1 housings, two 34" knockouts are supplied. The operating head is gasketed for sealing to the enclosure or customers panel on flush mounting switches.

The cam-operatedinserts are similar to those used with type PBC & WPBC pushbutton stations, with the following modifications: The operating plungers areglass-fibrereinforced plastic with a special lip overhang to interlock with the operating lever. Plungers are also equipped with location detents, corresponding to the cam development and speed points. This feature provides the operator with a “positive position feel.”
