SIRIUS S2 Power Contactor — 3RT2036-1AP60
Its main contact configuration is 18...1, and it carries a 480 V rated value of 52 A — the headline figure for motor switching under AC-3 duty.
Duty Cycle and Mechanical Life
Mechanical switching rates vary by duty: 1 000 1/h at AC-1 (resistive), 800 1/h at AC-3 and AC-3e (motor start/run), 600 1/h at AC-2 (slip-ring motor), and 250 1/h at AC-4 (plugging/inching). Typical mechanical life is 10 000 000 operations. Arcing time is 10...20 ms, with a closing time of 10...18 ms at AC — important for coordination with upstream protection.
Dimensions and Wiring
Dimensions: 130 mm depth, 55 mm width, 114 mm height. Main contact terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded wire.
