The ABB 1SDA054947R1 is a MIR-VB 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 means of coordinating the operation of two circuit breakers in installations where conflicting switching states must be prevented.
The MIR-VB vertical interlock is intended for arrangements where compatible Tmax circuit breakers are installed in a vertical configuration. Mechanical interlocking physically coordinates the breakers so that the permitted operating sequence is enforced without relying solely on electrical control logic.
Designed specifically for ABB SACE Tmax T4 and T5 circuit breakers, the 1SDA054947R1 is suitable for switchboards, source-transfer arrangements and industrial distribution systems requiring dependable mechanical interlocking between vertically arranged breakers.
A mechanical interlock physically coordinates the operation of associated circuit breakers so that an undesired switching combination cannot be selected. In source-transfer and interlocked distribution applications, this can help prevent both associated breakers from being placed in conflicting operating states at the same time.
The ABB 1SDA054947R1 MIR-VB is intended for compatible Tmax T4 and T5 breakers arranged vertically. Its mechanical operating principle makes it particularly useful in switchboards where dependable physical interlocking is required alongside, or independently from, electrical control and signalling systems.
