Schneider MasterPact MT 29352 Electrical Interlocking IVE 48-415V AC Circuit Breaker Accessory

The Schneider Electric 29352 is an IVE electrical interlocking accessory designed for MasterPact MT air circuit breakers.

This accessory provides electrical interlocking control between compatible circuit breakers to help prevent incorrect switching operations in power distribution systems.

The 29352 electrical interlocking unit operates with a 48–415 V AC control supply and is commonly used in applications requiring controlled transfer, source selection or coordinated breaker operation.

Unlike a standard circuit breaker component, the 29352 is an auxiliary control accessory that improves system operation reliability by managing the permitted closing sequence of connected breakers.

It is typically applied in electrical distribution systems where multiple power sources or backup supplies require coordinated switching logic.

For replacement projects, confirm the complete reference number because MasterPact accessories are designed for specific breaker families and installation configurations.
