This interlock system is completely combinable with any item in our catalogue – it can be added to an interlock sequence with other lock types.

In electrified premises without power, this interlock type prevents from manipulating any electric device (disconnector, switch, etc.) and leaving it open (doors, fences, etc.) until the manoeuvre is finished, i.e. when access is closed.

This lock is designed for an easy surface mounting on right hinged doors.

An HERPE lock is placed in an access gate (door, fence, etc.), implementing an interlocking sequence that can include a regular HERPE lock (ref.N101) on a switch or disconnector; a switchgear cabinet with an HERPE lock (ref.201); a solenoid commutator (ref.CS701) or a key selector (ref.A402), with the same key code as in the previous examples given. When the movable part of the access gate (door, fence, etc.) is open, the key stays trapped in the lock (ref.C301) and cannot be released until the gate is completely closed.
