Why Choose the ABB 1SDA073788R1 Emax 2 KLA Castell Key Lock?
The ABB 1SDA073788R1 is a KLA Castell key lock accessory designed for ABB SACE Emax 2 E1.2 air circuit breakers. Identified by ABB as KLA Key lock open Castell E1.2, it provides a mechanical locking arrangement that enables a compatible circuit breaker to be secured in the open position.
As part of the ABB SACE Emax 2 accessory range, this KLA lock is designed for integration with a Castell key interlocking system. Key interlocking provides controlled access to circuit breaker operation and can form part of a defined operating sequence between electrical equipment, helping prevent incorrect switching operations in low-voltage power distribution installations.
The 1SDA073788R1 is specifically intended for the Emax 2 E1.2 frame and provides an open-position locking interface for Castell systems. Its mechanical operation requires no control voltage and makes it suitable for switchboards where circuit breaker operation must be coordinated with maintenance procedures or mechanical interlocking schemes.

Mechanical Interlocking for Controlled Circuit Breaker Operation
Key interlocking systems provide a mechanical method of controlling the sequence in which electrical equipment can be operated. With a suitable Castell interlocking arrangement, the KLA accessory allows the Emax 2 circuit breaker to form part of a key-controlled operating sequence, helping ensure that switching actions occur only when the required mechanical conditions have been satisfied.
The ABB 1SDA073788R1 provides an open-position key locking interface for the Emax 2 E1.2 platform. It is particularly suited to switchboards where breaker operation needs to be coordinated with other equipment, access procedures or maintenance activities using a Castell trapped-key interlocking scheme.
