Why Choose the ABB 1SDA101987R1 Mechanical Interlock Support?
The ABB 1SDA101987R1 is a Type C mechanical interlock support designed for use between two fixed ABB Tmax XT7 or XT7M moulded-case circuit breakers. Part of ABB’s Tmax XT circuit-breaker accessory range, this version is specifically designed for wall-mounted installations where reliable mechanical interlocking is required.
Mechanical interlocking provides a physical means of preventing incompatible switching states between two circuit breakers. The 1SDA101987R1 provides the support arrangement required for a Type C mechanical interlock installation, helping create a dependable interlocking solution for power distribution and switching applications using compatible fixed XT7 and XT7M circuit breakers.
Designed as a genuine ABB accessory, the 1SDA101987R1 is engineered specifically for fixed XT7 and XT7M circuit breakers. The wall-mounted configuration makes it suitable for switchboards and electrical distribution assemblies where the associated breakers and interlocking system are installed on a wall-mounted support arrangement.

Reliable Mechanical Interlocking for Circuit Breakers
Mechanical interlocking is used in electrical distribution systems to physically coordinate the operation of circuit breakers and prevent switching combinations that must not occur simultaneously. Unlike control logic alone, a mechanical interlock provides a physical operating constraint between the associated switching devices.
The ABB 1SDA101987R1 is specifically designed to support a Type C mechanical interlock arrangement between two fixed XT7 or XT7M circuit breakers. Its dedicated wall-mounted configuration allows the interlocking arrangement to be integrated into compatible switchboards, distribution systems and industrial electrical installations.
Typical Applications
- Low-voltage electrical distribution switchboards.
- Power distribution and switching systems.
- Installations using fixed ABB XT7 or XT7M circuit breakers.
- Mechanical interlocking between two circuit breakers.
- Industrial electrical control and distribution panels.
- Wall-mounted circuit-breaker and interlock arrangements.
