It uses DC low-consumption coil technology and carries no built-in suppressor module, so you'll need to add a flyback diode or RC snubber externally if the circuit demands one.
This coil mounts onto the FK-series contactor frame — the same mechanical footprint as other TeSys FK coils. The control circuit voltage limits are tight: dropout at 0.2 to 0.35 Uc at 131 °F (55 °C), operational range 0.85 to 1.1 Uc at the same temperature. Ambient operating temperature spans -5 to 55 °C (23 to 131 °F). If your panel runs hotter than that, the coil may not hold in reliably.
