Siemens CLMC4C277 Lighting Contactor Coil 277 VAC

Siemens CLMC4C277 Lighting Contactor Coil is the 277 VAC control coil for Siemens CLM class lighting contactors, delivering a 30 A load rating and compatibility with 2-, 3-, and 4-pole configurations. The 277 V coil is designed for line-to-neutral control at 60 Hz, enabling direct connection to standard building power without a transformer. Siemens’ CLM coil data for 2–4 pole variants lists an energization inrush of about 410 VA and a dropout (hold) requirement of 40 VA, reflecting the coil’s electrical characteristics during operation. This coil is intended to be paired with CLM contactors to switch lighting loads up to 30 A in commercial applications, offering a compact, integrated solution within the CLM family’s mounting and electrical interfaces. The CLMC4C277 coil is specifically the 277 VAC option within Siemens’ CLM coil lineup, suitable for control panels and circuits that supply 277 VAC 60 Hz power, and designed to maintain reliable actuation of the associated contacts when energizing lighting loads.
