Why Choose the ABB 1SDA054946R1 MIR-HB Mechanical Interlock?

The ABB 1SDA054946R1 is a MIR-HB mechanical interlock accessory designed for compatible ABB SACE Tmax T4 and T5 moulded case circuit breakers. As part of the ABB SACE Tmax accessory range, it provides a mechanical interlocking solution for installations where the operating states of two circuit breakers must be coordinated.

Mechanical interlocking helps prevent incompatible switching conditions by physically linking the operation of associated circuit breakers. This makes the MIR-HB particularly useful in power distribution arrangements where two supply sources or switching devices must not be closed simultaneously.

Designed specifically for ABB SACE Tmax T4 and T5 circuit breakers, the 1SDA054946R1 provides a purpose-designed ABB interlocking solution for switchboards, changeover arrangements and industrial distribution systems requiring dependable mechanical coordination between breakers.

Key Advantages

  • Provides mechanical interlocking for compatible ABB Tmax circuit breakers.
  • Designed specifically for ABB SACE Tmax T4 and T5 circuit breakers.
  • Helps prevent incompatible simultaneous circuit breaker operating states.
  • Supports source changeover and supply interlocking arrangements.
  • Mechanical operation does not depend on an electrical control signal.
  • Suitable for industrial switchboards and power distribution systems.
  • Genuine ABB accessory engineered for integration with the SACE Tmax T range.

Key Features

  • ABB MIR-HB mechanical interlock.
  • Compatible with Tmax T4 and T5 moulded case circuit breakers.
  • Provides mechanical coordination between associated circuit breakers.
  • Designed to restrict conflicting breaker operating conditions.
  • Suitable for changeover and interlocked power distribution arrangements.

  • Designed for integration within compatible ABB Tmax switchboard installations.
  • Part of the ABB SACE Tmax circuit breaker accessory system.

Mechanical Circuit Breaker Interlocking

A mechanical circuit breaker interlock is used to physically coordinate the operation of associated breakers so that an undesired switching combination cannot be selected. Unlike an electrical interlock that depends on auxiliary contacts, wiring and control logic, the mechanical arrangement provides a direct physical restriction between the circuit breaker operating mechanisms.

The ABB 1SDA054946R1 MIR-HB is designed for compatible Tmax T4 and T5 circuit breakers and is suited to applications such as source changeover and interlocked distribution arrangements. By mechanically coordinating breaker operation, it can form an important part of a controlled switching system within industrial and commercial electrical installations.

Typical Applications

  • Industrial low-voltage distribution switchboards.
  • ABB Tmax T4 and T5 circuit breaker installations.
  • Normal and standby supply arrangements.
  • Generator and mains changeover systems.
  • Interlocked incoming circuit breaker arrangements.
  • Industrial and commercial power distribution systems requiring mechanical switching coordination.
