Schneider Electric LV429122 Molded Case Circuit Breaker

Schneider Electric LV429122 is a MA25 magnetic trip unit for ComPact NSX molded‑case circuit breakers, designed to mount on NSX100 and NSX160 frames in a 3‑pole configuration. This trip unit provides magnetic overcurrent protection with a fixed 25 A rating, enabling proper protection of three‑phase circuits in compact electrical distribution setups. As part of the NSX family, LV429122 is compatible with NSX100/160 breakers and, in some regional catalogs, NSX100‑250 frames, preserving the NSX line’s compact form factor. The MA25 trip unit is an accessory that coordinates with Schneider Electric's NSX breakers to deliver the magnetic tripping function, suitable for applications in distribution panels and motor control circuits where three‑phase protection is required. When selecting this accessory, confirm the target breaker frame size and ensure the 25 A magnetic rating aligns with your protection scheme and system design.
