FAQ

The LA4KE1FC is an RC (Resistor-Capacitor) surge suppressor. It is connected across the coil terminals (A1 and A2) to dampen high-voltage spikes that occur when the relay coil is de-energized, protecting sensitive electronics in the control circuit.

No, this is a control relay, not a power contactor. Its contacts are rated for a thermal current of 10A (AC-1) and are intended for control circuits (AC-15/DC-13). For switching motors, you should use a TeSys K power contactor like the LC1K series, sized appropriately for the motor's power rating.

A600 and Q600 are NEMA contact ratings for pilot duty applications. A600 applies to AC circuits, indicating it can make 6000VA and break 600VA at voltages up to 600V AC. Q600 applies to DC circuits, indicating a resistive load rating at specific DC voltages. These ratings confirm its suitability for industrial control applications in North America.
