Product details

What this SIRIUS Size S2 power contactor is

Rated 30 kW at 500 V AC-3 (motor switching), 22 kW at 400 V AC-2 (slip-ring motor duty), and 11.4 kW at 690 V. The AC-3 figure governs the motor-starting current you can safely switch — this contactor handles a 30 kW induction motor on a 500 V line. That range covers most panel wiring from 14 AWG through 4 AWG without adapters — wires up clean with a ring or fork terminal.

Mounting and environment

Pollution degree 3 means it tolerates conductive dust in a typical industrial panel environment.
