CHINT · Mechanical interlock
Product overview
The CHINT LMI-XB provides mechanical interlocking for a documented paired circuit-breaker arrangement, preventing associated main circuits from operating simultaneously.
Technical selection summary
| Exact model | LMI-XB; manufacturer accessory reference391935 |
|---|---|
| Family reference | NXB accessory group; confirm the exact breaker, pole/handle and mounting combination |
| Function | Mechanical mutual exclusion between the associated operating mechanisms |
| Operating scope | Mechanical arrangement; no source-sensing or automatic-transfer control function is established |
| Installation | Use the exact manufacturer outline and matching paired-breaker assembly |
| Circuit duty | Fault protection and current rating come from the selected circuit breakers, not from a standalone interlock rating |
Do not assume interchangeability with LMI-12, LMI-13 or another similar handle link. Verify the complete assembly and clearances. Mechanical interlocking is not independent overload or short-circuit protection.
