The NF22E-13 is a 4-pole contactor relay designed for switching auxiliary and control circuits in industrial control applications. It features an electronic coil interface that accepts a wide control voltage range of 100–250 V at 50/60 Hz or DC operation, with built-in surge protection eliminating the need for additional surge suppressors. The relay includes 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts compliant with IEC 60947-5-1, rated for 690 V operation in both auxiliary and main circuits. It delivers rated operational currents of 4 A at 220/240 V, 6 A at 24/127 V, 3 A at 400/440 V, and 2 A at 500–690 V for AC-15 duty, with maximum electrical switching frequencies of 1200 cycles per hour (AC-15) and 900 cycles per hour (DC-13). The NF22E-13 is ideal for applications requiring reliable control of large voltage variations worldwide without coil changes, offering mechanical switching frequencies up to 6000 cycles per hour and operating temperatures from -40 °C to +70 °C.
