Instructions/Data Sheet
This DBO and Hager devices conform with the following standards:
BS EN 61439-3 including Annex ZB.
Switch-disconnectors: BS EN 60947-3.
Residual Current Circuit Breaker (RCCB): BS EN 61008-1
Residual current operated circuit breaker with integral overload (RCBO): BS EN 61009-1
Miniature Circuit Breaker (MCB): BS EN 60898-1
Installation Instructions:
All product(s) must be installed by a suitably competent electrician
Giving consideration to their intended use and in accordance with the
current edition of BS 7671 (IET Wiring Regulations).
The Electricity at Work regulations and the Health and Safety at Work Act
shall be complied with.
Only equipment and arrangements specied in Hager’s technical
documentation / catalogue shall be used.
Install in the horizontal plane only.
Important notice:
To prevent potential overheating from loose connections the installer
shall check connections are tight to the torque levels stated in these
instructions prior to energizing this board. This check should include
factory made connections which may have loosened in transit.
Cable entry facilities:
Tightening torque values to be applied (Nm)
Switch-disconnector’s: 40A & 63A: 2.8 Nm
Switch-disconnector’s: 100A: 3.3 Nm
RCCB’s 40A & 63A: 2.8 Nm
RCCB’s 80A & 100A: 3.3 Nm
MCBs: 2.8 Nm
RCBO’s: 2.8 Nm
Earth & Neutral terminal bar connections: 2.0 Nm
Single conductors below 1.5mm² need to be doubled back in the
terminal bar
Front metal cover xing screws: 2.0 Nm
Good workmanship and proper materials must be applied by the installer.
The cable entry method shall, as far as reasonably practical, maintain the
non-combustable arrangement of the enclosure. Account shall be taken of
these instructions.
Metal Unit - Removing and replacing the terminal rail for cabling:
Metalclad units are provided with knockouts for standard 20, 25, and
32mm conduit and large rear knockouts.
Note: Only BASEC approved cable should be used
2
to 16mm2 for outgoing cables
1.0mm
up to 35.0mm2 for incoming live cables
Single conductors below 1.5mm² need to be doubled back in the terminal bar.

Pull and lift the terminal bar support away from the unit resting the rail
supported by the earth strap. After xing conduit/ cable glands, locate
the rail support and press down.
ZD0651 - Issue 3 03-15
Guidance Notes:
The total load must not exceed the rating of the incoming device or the assigned assembly rating (InA) whichever is the lower. Each neutral and earth
connection must correspond numerically to its outgoing way. Additional blanks (ref. JK01B) are available to cover spare ways.
A pack is provided to label this DBO, please consult us for spares or replacements.
Operating Instruction leaet is provided overleaf. This leaet should be left for the end user.
Single conductors below 1.5mm² need to be doubled back in the terminal bar.
DBOs incorporating RCDs in TT systems should incorporate an S type (time Delayed) RCCB, e.g. 100 mA s-type RCCB . Alternatively a main switch with
RCBO protection on all outgoing circuits should be used.
Precautions need to be taken to prevent faults to earth on the supply side of the RCD (as per BS7671 regulation 531.4.1)
IP Ratings:
Cable access into the DBO must maintain the integrity so far as reasonably practicable. In essence, for surfaces accessible after installation, this means
maintaining the requirement for the horizontal top surface of the enclosure to provide a degree of protection of at least IP4X and elsewhere, IP30. For
rear cable access, the minimum number of knockout(s) shall be removed.
IP Code Description
IP2XC Protection against access
IP30 Protection against access with
IP4X A probe of 1mm diameter
with a tool (2.5mm diameter,
100mm long) making contact
with live hazardous parts
a tool (2.5mm diameter, shall
not penetrate)
shall not enter the enclosure
Fitting Hager MCBs and RCBOs:
Only equipment and arrangements specied in Hager’s technical
documentation / catalogue shall be used.
1. Isolate the electrical supply from the DBO.
2. Remove the front cover.
3. Fully slacken the lower terminal of the device.
4. Fully open the bottom device clip (g 1.)
g 1.
Warranty
This distribution board is offered with a 24 month warranty against defective material or manufacture. If a warranty claim is necessary, please call the
technical support number given at the bottom of the page and we will be pleased to help.
For dimensional information and weights please consult the Hager catalogue.
5. Locate the device onto the din rail, and busbar. Ensure that the
busbar tooth is within the device terminal cage.
6. Close the bottom device clip.
7. While holding the device rmly onto the busbar, fully tighten the lower
terminal screw.
8. After tting all outgoing devices and connecting all outgoing cables,
please check the tightness of all cable connections. This should
include all factory made connections, which may have loosened
during installation or transit.

Note: RDF only applies to continuously and simultaneously loaded
circuits.
In principle, this means adjacent circuit-breakers having a load
‘on’ time exceeding 30 minutes or where a load not exceeding 30
minutes has an ‘off’ time less than the ‘on’ time, will need to have
the rated diversity factor applied as indicated.
