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.
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.
