The coil is 24 VDC with spring-type terminals — no screwdriver needed for the coil connection, which speeds up panel wiring. Main contact ratings are given for multiple voltages: 10 A at 24 V, 2 A at 48 V, 1 A at 110 V, 0.3 A at 220 V, and 3 A at 400 V. Switching frequency depends on duty: 1000 cycles/hour for AC-1 resistive loads, 750 for AC-2 and AC-3 motor starting, and 250 for AC-4 plugging/inching. The arcing time runs 10 to 15 ms at 50/60 Hz.
Depth is 73 mm, height 70 mm. Wire sizes accepted: solid or stranded 0.5 to 4 mm², or two conductors of 0.5 to 4 mm² per terminal.
