Product details

SIRIUS Size S2 Power Contactor — 52 A at 480 V AC-3

The Siemens 3RT2036-3AL20 is a SIRIUS power contactor in the Size S2 frame, rated 52 A at 480 V AC-3 for switching three-phase motor loads up to that current in a standard 480 V distribution. The coil terminals are spring-type (cage clamp), accepting 2x (0.5... 2.5 mm²) solid or stranded — no screwdriver needed on the coil side for fast panel wiring.

Integration — Panel Fit & Clearances

Dimensions: 55 mm wide, 114 mm tall, 130 mm deep.

Switching Performance & Mechanical Life

Mechanical life typical 10,000,000 operations. Maximum switching rates: AC-1 1,000 cycles/h, AC-3 800 cycles/h, AC-4 250 cycles/h. Arcing time 10...20 ms; closing time 10...18 ms. Auxiliary switch built in; main contact configuration 18...1.

Frequently asked questions

Will 3RT2036-3AL20 drop into a panel specified for 3RT2015-2AP02?

The 3RT2036-3AL20 is a Size S2 frame (55 mm wide, 114 mm tall, 130 mm deep) and is physically larger than the smaller Size S0 frame of the 3RT2015-2AP02. It will not drop into the same footprint without panel modifications — check the mounting hole pattern and DIN rail clearance before substituting.
