1SDA062127R1 ABB T7-T7M-X1 Mechanical Interlock Cable Kit

Why Choose the ABB 1SDA062127R1 T7-T7M-X1 Mechanical Interlock Cable Kit?

The ABB 1SDA062127R1 is a mechanical interlock cable kit designed for compatible ABB Tmax T7, T7M and Emax X1 circuit-breaker installations. It provides the cable connection required to mechanically interlock two circuit breakers, helping prevent both breakers from being placed in the closed position simultaneously.

Designed for horizontal or vertical mechanical interlocking arrangements, the kit provides installation flexibility for switchboard builders working with different circuit-breaker layouts. The assembly contains two mechanical interlock cables, each 1370 mm long, providing the physical transmission required between the two compatible switching devices.

As part of the ABB Tmax T4–T8 accessory range, the 1SDA062127R1 is intended for applications such as source changeover, mains-generator arrangements and other distribution systems where mechanical prevention of simultaneous circuit-breaker closing is required. The cable kit is used together with the appropriate mechanical interlock plates or mechanisms selected for the circuit-breaker installation.

Reliable Mechanical Interlocking Between Circuit Breakers

A mechanical interlock physically coordinates the operating mechanisms of two circuit breakers so that incompatible switching states can be prevented independently of an electrical control system. In a typical two-breaker arrangement, the interlock prevents both associated breakers from being closed at the same time, supporting safe source selection and controlled switching sequences.

The ABB 1SDA062127R1 provides two 1370 mm cables for horizontal or vertical mechanical interlocking arrangements involving compatible T7, T7M and X1 equipment. The cable kit forms part of the complete interlocking system and is used with the appropriate ABB mechanical interlock plates or mechanisms required for the specific circuit-breaker versions and mounting arrangement.

Typical Applications

• Mains and generator circuit-breaker interlocking.
• Normal and alternative supply changeover systems.
• Industrial low-voltage switchboards.
• Horizontal or vertical two-breaker interlock arrangements.
• Power distribution systems requiring mutually exclusive breaker operation.
• ABB Tmax T7, T7M and Emax X1 circuit-breaker installations.
