The ABB 1SDA073821R1 is a KLP-A Castell position lock with a two-key configuration for ABB Emax 2 E2.2 through E6.2 air circuit breakers. Part of the ABB Emax 2 air circuit breaker accessory range, this mechanical locking accessory is intended for applications requiring controlled circuit breaker positioning as part of a key-operated interlocking arrangement.
Using a Castell trapped-key locking system, the KLP-A accessory can support defined switchboard operating sequences by mechanically controlling access to circuit breaker positioning. The two-key configuration is particularly suited to installations where coordinated interlocking is required between circuit breakers, switchgear sections or other compatible equipment.
The 1SDA073821R1 is designed for ABB Emax 2 E2.2 through E6.2 circuit breakers, covering the E2.2, E4.2 and E6.2 frame sizes. Its mechanical operation requires no auxiliary control voltage, providing a robust position-locking solution for industrial and commercial low-voltage power distribution systems.
Trapped-key interlocking uses a defined sequence of mechanical key release and retention to control how equipment can be operated. In low-voltage switchgear, this approach can be used to establish controlled operating sequences and prevent incompatible equipment states without relying solely on electrical interlocking logic.
The ABB 1SDA073821R1 combines KLP-A position locking with a Castell two-key arrangement for compatible Emax 2 E2.2, E4.2 and E6.2 circuit breakers. This makes it suitable for switchboards where circuit breaker positioning forms part of a wider mechanical interlocking philosophy involving multiple items of electrical equipment.
