Schneider Electric LC11021 Shunt Trip for LC Frame Breakers

Schneider Electric LC11021 is a shunt-trip accessory for legacy LC-frame circuit breakers, enabling remote tripping by energizing a control coil. The device accepts 120 to 240 VAC at 50/60 Hz, a range that covers typical control circuits and aligns with standard building automation and safety interlock systems. Built to mount with LC-frame breakers, LC11021 adds remote disconnection capability without replacing the main breaker, helping preserve existing installations while expanding emergency or automatic safety shutdown options. As part of Schneider Electric's Square D circuit-breaker accessories, LC11021 preserves the LC-frame mounting geometry and electrical interface, ensuring straightforward installation on compatible LC-series devices without invasive modification. When the coil receives its rated voltage, the shunt-trip mechanism actuates to trip the breaker, providing a rapid, remote means of isolating a protected circuit under safety or control conditions. This accessory is intended for use with legacy LC-frame breakers and should be wired and energized in accordance with applicable electrical codes and system design guidelines.
