Industrial LV426937 Limit Switch Shaft Operator NSMP

LV426937 Open door shaft operator for extended rotary handles (NSXm) from Schneider Electric is a compact, DIN-rail mounted accessory that enables manual operation of circuit breakers and switches when the switchboard door is open. Designed for front mounting on extended enclosures, it supports a broad family of Schneider Electric devices, including PowerPact (B, H, J, L), ComPact NSXm and NSX, along with TeSys GV4 and BV4 lineups, making it a versatile upgrade for panel assemblies. The unit is specified as an open-door shaft operator intended to cooperate with extended rotary handles, reducing the need for awkward cable routing and improving access during maintenance or testing. It is a small-form accessory with a documented weight of 60 g and packaging dimensions around 2.9 cm in height, 5.7 cm in width, and 9.5 cm in length, reflecting its lightweight, space-saving footprint. By providing a reliable mechanical link between the door and the operating mechanism, LV426937 helps ensure safe, convenient control of devices even when the cabinet is opened, aligning with typical field requirements for easier manual operation and quick restoration of service.
