Why Choose the ABB 1SDA107500R1 KLC-A Castell Key Lock?
The ABB 1SDA107500R1 is a KLC-A Castell key-lock arrangement designed specifically for the ABB SACE Tmax XT7M moulded-case circuit-breaker platform. ABB identifies the accessory as KLC-A Key lock open Castell XT7M, providing a dedicated arrangement for incorporating a Castell key interlock into the breaker operating mechanism.
This accessory is intended for locking the XT7M in the open position, supporting controlled operating sequences in switchboards where access or switching operations need to be governed by a mechanical key-interlocking system. Castell key interlocking is widely used in electrical installations to establish defined operating sequences between interconnected equipment.
ABB describes the 1SDA107500R1 as “KEY LOCK CASTELL IN OPEN (PREDISPOSITION ONLY) XT7M”. The accessory is therefore a predisposition arrangement for the Castell locking system rather than a complete stand-alone lock assembly, and ABB specifies this XT7M version as a factory-mounted-only configuration.

Mechanical Key Interlocking for XT7M Switchgear
Mechanical key interlocking can be used to establish controlled switching sequences between circuit breakers, isolators, access doors and other equipment. By requiring the correct key sequence before an operation can proceed, an interlocking scheme can help prevent operating states that have been excluded by the switchgear design.
The ABB 1SDA107500R1 provides the Castell key-lock predisposition for an XT7M breaker in the open position. Because ABB specifies this particular arrangement as factory mounted only, it should be selected as part of the appropriate XT7M breaker configuration when a Castell-based interlocking scheme is required.
Typical Applications
- ABB SACE Tmax XT7M circuit-breaker installations.
- Castell mechanical key-interlocking systems.
- Low-voltage main distribution switchboards.
- Generator and mains switching arrangements.
- Industrial power-distribution systems.
- Critical infrastructure and process installations.
- Switchgear requiring controlled operating sequences with the XT7M locked in the open position.

Frequently Asked Questions
What is the ABB 1SDA107500R1?
It is a KLC-A Castell key-lock predisposition for the ABB SACE Tmax XT7M circuit breaker, designed for a locking arrangement in the open position.
Which circuit breaker is compatible with the ABB 1SDA107500R1?
ABB specifies the 1SDA107500R1 specifically for the SACE Tmax XT7M circuit-breaker platform.
Which locking system is used with the ABB 1SDA107500R1?
The accessory is designed for a Castell mechanical key-interlocking system.
Which circuit-breaker position does the ABB 1SDA107500R1 lock?
The KLC-A arrangement is specified for locking the compatible XT7M circuit breaker in the open position.
Is the ABB 1SDA107500R1 supplied as a field-installable complete Castell lock?
No. ABB describes this product as “predisposition only” and specifies the XT7M KLC-A Castell arrangement as factory mounted only. It should therefore be selected as part of the appropriate breaker configuration rather than treated as a complete field-installable Castell locking system.
Designed for Controlled ABB Tmax XT7M Switching
ABB mechanical interlocking accessories provide coordinated solutions for SACE Tmax XT circuit breakers, helping switchboard designers implement controlled operating sequences using recognised key-interlocking systems such as Castell.
