1SDA054952R1 ABB MIR-P Type E T5-T5 Mechanical Interlock

Why Choose the ABB 1SDA054952R1 MIR-P Mechanical Interlock?

The ABB 1SDA054952R1 is a MIR-P Type E mechanical interlock for compatible ABB SACE Tmax T5 moulded case circuit breakers. Identified as MIR-P tipo E (T5-T5), this genuine ABB accessory is designed to mechanically interlock two T5 circuit breakers so that their operating states can be coordinated.

Mechanical interlocking is used where two breakers must not be permitted to assume conflicting operating states simultaneously. By creating a direct mechanical relationship between the associated breakers, the MIR-P provides interlocking independently of an electrical control signal, making it suitable for power-transfer, source-selection and other mutually interlocked switching arrangements.

The 1SDA054952R1 is the Type E configuration for a T5-T5 breaker combination. Its dedicated ABB design provides coordinated compatibility with the associated Tmax equipment and supports professional implementation of mechanically interlocked low-voltage distribution systems.

Mechanical Interlocking for Tmax T5-T5 Arrangements

A mechanical interlock establishes a physical relationship between circuit breaker operating mechanisms so that predetermined combinations of breaker states are restricted. This is particularly useful in installations with two power sources or distribution paths where simultaneous connection must be prevented by the switching arrangement.

The ABB 1SDA054952R1 provides a Type E MIR-P interlocking solution for two compatible Tmax T5 breakers. Because the interlocking action is mechanical, it provides the required operating constraint without relying solely on electrical logic, making it a useful component in coordinated source-selection and transfer systems.

Typical Applications

• Interlocking two ABB Tmax T5 circuit breakers.
• Main and standby power-source arrangements.
• Source-selection systems.
• Power-transfer switchboards.
• Industrial low-voltage distribution systems.
• Switchboards requiring mechanically coordinated breaker operation.
