CHINT LMI-XB Mechanical Interlock,
is designe to ensure that two main circuits cannot be operated simultaneously.
It combines two-stage (or multi-stage) circuit breakers with an interlock conversion mechanism for safe manual switching between power sources.
Suitable for residential, commercial, and industrial applications, such as hotels, offices,
and shopping centers, it enhances system safety by preventing short-circuits or parallel connections.
The compact 9 mm design, wide –35 °C to +70 °C temperature range, and simple DIN-rail installation make it reliable and easy to use
