Product details

SIRIUS S2 power contactor, 48 VDC coil

Coil holds at 48 VDC nominal. DC switching capability is specified across multiple voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. Maximum switching rates vary by duty: 1,000 cycles/hour at AC-1, 800 at AC-3, and 300 at AC-4.

Main current circuit terminals are screw-type, accepting solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²). A second stranded range is listed as 2x (0.75 to 16 mm²). At 40 °C, the minimum permissible conductor size is 16 mm². The contactor footprint is 55 mm wide, 112 mm high, and 179 mm deep. Pollution degree 3 (industrial environment) applies.
