Product details

SIRIUS S2 frame, screw terminals, DIN-rail snap

The 3RT2036-1NB30: It carries an integrated auxiliary switch block (1 NO + 1 NC by default), saving a separate add-on for basic feedback or interlock circuits.

Coil circuit and operating envelope

The coil is rated for a control voltage of 20–33 V, with a pick-up threshold at 0.8× rated (16 V minimum) and a drop-out ceiling at 1.1× rated (36.3 V max).

Duty-cycle limits and thermal constraints

The contactor is rated for different switching frequencies depending on the duty class: 1,000 cycles/hour in AC-1 (resistive), 800 in AC-3 (squirrel-cage motor start/run), 600 in AC-2 (slip-ring motor), and 250 in AC-4 (plugging/inching).
