Why Choose the ABB IT MP T4 P 4p Interlock?

The ABB IT MP T4 P 4p, order code 1SDA054840R1, is an interlock accessory for ABB SACE Tmax T4 four-pole moulded-case circuit breakers. It is designed for installations where two circuit breakers must be mechanically coordinated so that incompatible switching states cannot occur simultaneously.

The IT MP mechanical interlock arrangement provides a physical operating constraint between compatible circuit breakers. This makes it particularly useful in power-transfer and changeover applications where the installation must prevent two supplies or switching paths from being connected at the same time.

Designed for the ABB SACE Tmax T4 platform and a four-pole configuration, the accessory provides a purpose-engineered solution for integrating mechanical interlocking into low-voltage distribution assemblies while maintaining compatibility with the Tmax circuit breaker system.

Key Advantages

  • Genuine ABB SACE Tmax T4 mechanical interlocking accessory.
  • Designed for four-pole Tmax T4 circuit breaker installations.
  • Provides a mechanical method of preventing incompatible simultaneous circuit breaker operating states.
  • Well suited to changeover and power-transfer arrangements.
  • Mechanical operation does not depend on an electronic control system to provide the physical interlocking function.
  • Purpose-designed for integration with compatible ABB SACE Tmax T4 moulded-case circuit breakers.

Key Features

  • ABB SACE Tmax T4 accessory.
  • IT MP mechanical interlock configuration.
  • Designed for compatible four-pole circuit breakers.
  • Provides mechanical coordination between compatible switching devices.
  • Supports interlocked source-transfer and changeover applications.
  • Suitable for integration into low-voltage switchboards and distribution panels.
  • Part of the ABB Tmax T4–T8 accessory family.

Mechanical Interlocking for Power Transfer and Changeover Systems

Mechanical interlocking is commonly used where two circuit breakers control alternative power paths and must not be closed in an incompatible combination. The ABB IT MP T4 P 4p provides a physical interlocking function for compatible Tmax T4 devices, helping establish a defined switching relationship between the breakers.

This type of arrangement is particularly valuable in mains-to-generator, mains-to-mains and other source-transfer systems. By incorporating a mechanical constraint into the switching assembly, the interlock complements the wider electrical control strategy and helps prevent simultaneous operating states that the installation is designed to exclude.

Typical Applications

  • Mains-to-generator changeover systems.
  • Alternative mains supply transfer arrangements.
  • Industrial low-voltage switchboards.
  • Commercial power distribution panels.
  • Interlocked incomer circuit breaker arrangements.
  • Four-pole ABB SACE Tmax T4 transfer and changeover assemblies.
