Product details

Integrator's spec recap — 3RT2035-1CK64-3MA0

It carries a 40 A rating at 480 V and a 7.5 hp rating at 230 V, which defines its motor-switching capability for typical three-phase induction motors in that power band. The magnet coil uses screw-type terminals, and the main contact configuration is 18 normally open contacts to 1 normally closed contact. Mechanical life is listed at 10,000,000 typical operations.

Maximum operating rates vary by duty: 1,200 operations per hour at AC-1, 750 at AC-2, 1,000 at AC-3, 1,000 at AC-3e, and 300 at AC-4. The coil operates at 110 V at 50 Hz. Auxiliary contact ratings at various voltages: 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.6 A at 440 V.
