1SDA062159R1 ABB T7-T7M-X1 Mechanical Compartment Door Lock with Cables

Why Choose the ABB 1SDA062159R1 T7-T7M-X1 Mechanical Compartment Door Lock?

The ABB 1SDA062159R1 is a mechanical compartment door lock with cables designed for compatible ABB SACE Tmax T7 and T7M circuit-breaker installations. The accessory provides a mechanical interlocking function between the circuit breaker and its switchboard compartment door, helping prevent the compartment door from being opened while the circuit breaker is in the closed position.

As part of the ABB Tmax T4–T8 accessory range, the 1SDA062159R1 uses a cable-operated mechanical arrangement to transfer the breaker operating state to the compartment-door locking mechanism. This provides an additional physical operating constraint within switchgear assemblies without relying on an electrical control supply.

The COMPART.DOOR INTERLO.DEV.CABLE T7-T7M-X1 is suitable for both Tmax T7 and T7M applications. ABB specifies that the accessory is used together with the appropriate interlock cable kit and interlock plate consistent with the circuit-breaker configuration, allowing switchboard builders to integrate the door-locking function into the complete assembly.

Key Advantages

• Provides mechanical compartment-door interlocking for compatible ABB circuit breakers.
• Helps prevent the switchgear compartment door from being opened while the circuit breaker is closed.
• Compatible with ABB SACE Tmax T7 and T7M installations.
• Cable-operated mechanical design requires no electrical control supply.

• ABB mechanical compartment door lock.
• Supplied as a door interlock device with cables.
• Designed to lock the compartment door when the circuit breaker is closed.
• Compatible with Tmax T7 and T7M circuit breakers.
• Mechanical operating principle.
• No normally open or normally closed electrical auxiliary contacts.
• Suitable for switchboard compartment access control.
• Requires the appropriate interlock cable kit and interlock plate for the circuit-breaker configuration.
• Part of the ABB SACE Tmax T accessory family.
• Designed in accordance with IEC requirements.

Reliable Mechanical Compartment Door Interlocking

A mechanical compartment door interlock links the circuit breaker's operating condition to the switchboard door mechanism. With the ABB 1SDA062159R1 installed as part of the appropriate interlock arrangement, the compartment door is mechanically restrained when the associated circuit breaker is closed, providing controlled access to the breaker compartment.

ABB specifies that the 1SDA062159R1 must be combined with the appropriate cable kit and interlock plate consistent with the circuit breaker. ABB also states that a circuit breaker equipped with this mechanical compartment door lock cannot simultaneously be mechanically interlocked with another circuit breaker, an important consideration when designing the complete switchgear interlocking scheme.

Typical Applications

• Industrial low-voltage switchboards.
• ABB SACE Tmax T7 and T7M circuit-breaker installations.
• Mechanical switchgear compartment-door interlocking.
• Electrical distribution panels requiring controlled compartment access.
• Industrial power distribution and motor-control switchboards.
• OEM switchgear assemblies requiring mechanical door-to-breaker interlocking.
