Product details

SIRIUS S2 power contactor — 175-280 V coil, screw terminals

The Siemens 3RT2036-1NP30 is a SIRIUS S2 power contactor rated for a 175-280 V AC/DC coil, with screw-type terminals on both coil and main contacts.

At 130 mm deep, 55 mm wide, and 114 mm tall, this S2-frame contactor fits standard panel layouts. The screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire, so it ties into existing ring-tongue or ferrule terminations without adapter blocks.

Coil and switching performance

Operating range is 0.8 to 1.1 times the rated voltage (175-280 V), so it holds in during brownout conditions down to 140 V. That means it's suitable for moderate-speed sequencing without excessive contact wear. Maximum switching rates vary by duty: 1,000 cycles/hour at AC-1 (resistive), 800 at AC-3 (motor start/run), and 250 at AC-4 (plugging/inching). The AC-3e rating matches the AC-3 figure at 800 cycles/hour, confirming it's optimized for standard motor starting duty.
