Product details

SIRIUS 3RT6025-1AB00 — Power Contactor, Size S0

AC-3 rated voltage is 690 V maximum, with motor power ratings of 13.3 kW at 230 V, 23 kW at 400 V, and 40 kW at 690 V (all at 60 °C ambient). The insulation voltage is also rated 690 V.

Side-by-side mounting is permitted. Dimensions are 45 mm width, 85 mm height, 97 mm depth — the depth is the dimension that extends into the panel, so verify enclosure depth clearance against the 97 mm figure.

Substance prohibitance date is 05/01/2012, indicating RoHS compliance from that date. Pollution degree 3 (industrial environment).
