Schneider Electric LA11027U DC Coil Contactor

LA11027U is Schneider Electric's 24 VDC shunt-trip accessory for PowerPact LA/LH/Q4 circuit breakers (often listed as LA11027). Energizing the 24 V DC coil from a remote control circuit trips the associated breaker, providing remote disconnection in emergency or planned shutdown scenarios. This accessory is designed specifically for the PowerPact LA, LH, and Q4 breaker families and is used to create a dedicated path for remote trip signals without requiring operator intervention at the breaker itself. When the control circuit energizes the coil, the trip mechanism actuates, opening the main contacts and interrupting current flow. The 24 VDC coil makes it compatible with common low-voltage control systems found in industrial panels and distribution assemblies that rely on remote-control safety interlocks or interlocking schemes. As part of Schneider Electric's PowerPact line, the LA11027U offers a standardized method to add remote-trip capability to compatible breakers, helping meet safety and control requirements in automation and power distribution setups.
