The Schneider Electric LV429290 is a 4-pole plug-in kit rated 250 A for fixed ComPacT NSX100, NSX160 and NSX250 circuit breakers. It converts a fixed breaker into a plug-in configuration that can be installed or extracted without connecting or disconnecting the power circuit. The kit bundles a plug-in base, power connections, two short terminal shields and a safety trip interlock.
Specify this 4P kit for 4-pole fixed NSX100-250 breakers; choose the 3P kit (LV429289) instead for 3-pole devices. The included safety trip interlock (LV429270) is mandatory and already part of the set, so no separate interlock needs to be ordered alongside the kit.
