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.","metaTitle":"Schneider TeSys K LC1K09103D72 Contactor, 3P, 9A AC-3, 42V C","metaDescription":"Active-production TeSys K contactor, 3P, AC-3 9A at ≤440V, 4kW motor rating at 480V, 42V AC coil with built-in peak limiting diode.
