Why Choose the ABB 1SDA073793R1 KLC-S Key Lock?
The ABB 1SDA073793R1 is a KLC-S key lock designed to lock ABB Emax 2 air circuit breakers in the open position. Part of the ABB Emax 2 air circuit breaker accessory range, this mechanical locking accessory provides key-operated control to help prevent unintended closing of the circuit breaker while the lock is engaged.
This KLC-S version uses key number N.20006 and provides a practical mechanical locking solution for installations where circuit breaker operation must be restricted during isolation, maintenance or defined switchboard operating procedures. The key-operated mechanism allows authorised personnel to control when the breaker can be released from its locked-open condition.
The 1SDA073793R1 is designed for ABB Emax 2 E2.2 through E6.2 air circuit breakers, covering the E2.2, E4.2 and E6.2 frame sizes. As a mechanical accessory, the KLC-S requires no auxiliary electrical supply or control wiring, making it a straightforward addition to compatible low-voltage switchgear installations.

Reliable Open-Position Circuit Breaker Locking
A key lock in the open position provides a mechanical means of preventing a circuit breaker from being closed while the locking mechanism is engaged. This functionality is useful in power distribution systems where breaker operation must be controlled during maintenance, electrical isolation or specific operating sequences.
The ABB 1SDA073793R1 uses the N.20006 key number and extends KLC-S open-position locking across the larger Emax 2 E2.2, E4.2 and E6.2 frames. Its entirely mechanical operation provides a simple and dependable locking method without requiring control power or additional electrical signalling.
Typical Applications
- ABB Emax 2 E2.2 air circuit breaker installations.
- ABB Emax 2 E4.2 and E6.2 air circuit breaker installations.
- Circuit breaker open-position locking.
- Industrial low-voltage switchboards and distribution panels.
- Electrical isolation and maintenance procedures.
- Commercial and industrial power distribution systems.
