Why Choose the ABB KLA Castell E2.2...E6.2 Key Lock Provision?
The ABB KLA Castell E2.2...E6.2, order code 1SDA073797R1, is a mechanical key-lock provision for locking compatible ABB SACE Emax 2 air circuit breakers in the open position. Designed for the E2.2, E4.2 and E6.2 frames, it provides the breaker-side preparation required for integration with a Castell key-lock system.
The accessory forms part of ABB's key lock in open position system. When the appropriate Castell lock is incorporated into the installation, the arrangement can prevent the circuit breaker from being closed while the key-lock mechanism is engaged, supporting controlled switching procedures and mechanical interlocking schemes within low-voltage switchgear.
The 1SDA073797R1 is supplied as the Castell predisposition / provision; the Castell key lock itself is supplied separately by the customer. ABB specifies this version for SACE Emax 2 E2.2, E4.2 and E6.2 breakers, making it a dedicated mechanical accessory for installations requiring Castell trapped-key or key-interlocking arrangements.

Reliable Castell Key Interlocking for Emax 2
Key-lock systems provide a mechanical method of controlling the sequence in which electrical equipment can be operated. On an Emax 2 circuit breaker, an open-position key-lock arrangement can be used to secure the breaker against closing until the required key and operating conditions are present. This is particularly useful where switching sequences must be coordinated between multiple pieces of equipment.
The ABB KLA Castell accessory provides the dedicated Emax 2 interface for this type of arrangement. Because the Castell lock itself is customer-supplied, the provision allows the breaker to become part of a wider Castell key-interlocking scheme designed around the requirements of the switchboard or installation.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers.
- Castell key-interlocked switchboards.
- Controlled electrical switching sequences.
- Generator and mains interlocking arrangements.
- Industrial low-voltage power-distribution systems.
- Critical-power, infrastructure and process switchgear.
