1SDA062131R1 ABB T7-T7M Withdrawable Mechanical Interlock Plate

Why Choose the ABB 1SDA062131R1 T7-T7M-X1 Mechanical Interlock Plate?

The ABB 1SDA062131R1 is a dedicated mechanical interlock plate designed for compatible ABB SACE Tmax T7 and T7M circuit breakers. Identified within ABB's mechanical interlocking accessory range as a plate for T7-T7M withdrawable circuit breaker configurations, it forms part of a cable-operated interlocking system used to coordinate the operating states of two circuit breakers.

As part of the ABB SACE Tmax T accessory range, the 1SDA062131R1 provides the mechanical mounting and interface required for interlocking compatible T7 and T7M breakers. When installed as part of the complete ABB cable interlock arrangement, it helps prevent prohibited simultaneous breaker positions and supports controlled operation in power changeover and distribution systems.

The plate is intended for withdrawable T7 and T7M circuit breaker installations. ABB specifies that a complete mechanical interlocking arrangement between two compatible breakers requires two interlock plates and one cable interlock kit, allowing the mechanical state of the breakers to be coordinated without dependence on an electrical control supply.

Reliable Mechanical Interlocking for T7 and T7M Circuit Breakers

Mechanical interlocking is used where the operating positions of two circuit breakers must be physically coordinated. By connecting the breaker mechanisms through a cable-operated interlock arrangement, the ABB system helps prevent operating combinations that are not permitted by the electrical distribution design.

The ABB 1SDA062131R1 provides the breaker-mounted interlock plate required for compatible withdrawable Tmax T7 and T7M installations. A complete two-breaker system uses one interlock plate on each breaker together with the appropriate cable kit, making the arrangement particularly suitable for mains-generator changeover, dual-source distribution and other applications requiring mechanically enforced breaker coordination.

Typical Applications

• ABB SACE Tmax T7 and T7M withdrawable circuit breaker installations.
• Mechanical interlocking between two circuit breakers.
• Mains and generator changeover systems.
• Normal and emergency power supply arrangements.
• Industrial low-voltage switchboards.
• Dual-source and bus-coupler distribution systems.
