Product details

SIRIUS S10 power contactor — main terminal sizing and duty-cycle limits

The 3RT1064-2AB36: Switching frequency varies by duty class: up to 750 operations per hour in AC-1 (resistive), 500/h in AC-3 (motor start/run), and 130/h in AC-4 (plugging/inching). The AC-3e rating also caps at 500/h. These are the maximum mechanical limits — actual thermal capacity depends on the load current and ambient temperature.

Panel fit and mounting flexibility

Dimensions are 202 mm deep, 145 mm wide, and 210 mm high. Mounting is by screw fixing through 11 mm diameter holes.

Auxiliary contact ratings and coil data

The contactor includes an auxiliary switch. The coil operates on a rated value of 23-26 V with an initial inrush factor of 0.8 and a full-scale factor of 1.1. Arcing time is 10-15 ms. Operating times (closing/opening) are 40-80 ms for both AC and DC supplies.
