The LC1K09103D72: Motor power: 2.2 kW at 220…230 V AC, 4 kW at 380…415 V, 440 V, 480 V, 500…600 V, and 660…690 V — all at 50/60 Hz.
Coil and thermal management
The 42 V AC coil includes a built-in bidirectional peak limiting diode suppressor — no external flyback diode or RC snubber needed across the coil terminals. This matters when the contactor is driven by a PLC output or a relay: the integrated suppression limits voltage spikes that could damage solid-state outputs. Heat dissipation is 1.3 W at rated coil voltage, a figure to include in enclosure thermal calculations when multiple contactors are ganged on a DIN rail.
Physical fit and compliance
The 3-pole configuration with 3 normally-open main contacts and 1 NO auxiliary contact covers the basic motor-starting circuit without needing a separate aux block for simple applications.
