5. Description
Protections and locks
Various different mechanical and electromechanical protection devices and locks are available.
15 Locking magnet on truck (-RLE2)
This accessory is mandatory in withdrawable
versions for UniGear ZS1 switchgear and PowerCube
modules to prevent the circuit-breaker from being
racked into the switchgear when the plug of the
auxiliary circuits is disconnected.
The plug also creates an anti-insertion lock against
different rated currents. Striker pins prevent the
plug from being plugged into the socket if the
circuit-breaker's rated current is lower than the
rated current of the panel.
Note: a specific version for the circuit-breakers of
ZS8.4 switchgear is available on request. This
accessory is not available when the motor-operated
truck is required.

16 Interlock for fixed circuit-breaker
Device for fixed circuit-breakers converted into
plug-in by the customer. Allows the customer to
create a mechanical lock that inhibits racking-out/
racking-in when the circuit-breaker is closed and
prevents the circuit-breaker from closing during
movement.
Note. The device must be requested when the order
is placed since it must be assembled in the factory.
