Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position that allows +/-180° rotation on a vertical surface and +/-22.5° forward/backward tilt. Envelope dimensions are 55 mm wide, 114 mm high, and 130 mm deep — the depth is the dimension that typically drives cabinet depth when panel-mounted.

Coil and auxiliary contact ratings

Auxiliary contacts are rated for 10 A at 24 V, stepping down to 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V — these are the DC switching limits for the built-in auxiliary switch block.

Switching frequency and endurance

Maximum switching frequency varies by duty: 1,000 operations per hour at AC-1, 600 at AC-2, 800 at AC-3 and AC-3e, and 250 at AC-4.

Environmental and wiring

Main contact terminals accept 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²) solid or stranded wire.

Frequently asked questions

What coil voltage does this contactor use?

Rated coil voltage range is 20-33 V, with screw-type terminals on the magnet coil.

Will 3RT2036-1NB30-ZX95 drop into a panel specified around 3RT2015-1BW42?

The 3RT2036 is an S2 frame size, while the 3RT2015 is a smaller S0 frame — physical dimensions differ, so it will not directly swap without panel rework.
