Product details

SIRIUS S12 Contactor for Heavy Motor and Resistive Loads

Its coil accepts 21 to 27.3 V AC/DC, making it suitable for standard 24 V control systems with tolerance for voltage drop or ripple. The main power circuit accepts stranded conductors from 70 up to 240 mm², sized for high-current feeders typical of large motors or distribution.

Mounts via screw fixing (four holes, 11 mm diameter) to a vertical panel surface. Dimensions are 214 mm high, 160 mm wide, 225 mm deep.

Auxiliary Contact Ratings and Switching Performance

An auxiliary switch is included. Its rated switching currents vary by voltage: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V. These ratings cover typical control circuit voltages for signaling and interlocking. The contactor's mechanical endurance is typically 10,000,000 operations.

Frequently asked questions

What is the coil voltage range for this contactor?

The coil is rated for 21 to 27.3 V AC/DC, so it works on nominal 24 V control supplies with tolerance for variation.

What size conductors does the main power circuit accept?

The main terminals accept stranded conductors from 70 mm² up to 240 mm², suitable for high-current motor feeders.

What are the physical dimensions of the 3RT1476-6NB36?

The contactor measures 214 mm high, 160 mm wide, and 225 mm deep. Mounting requires four 11 mm diameter holes with specified clearances.

What auxiliary contact ratings does this contactor have?

The auxiliary switch is rated 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 6 A at 230 V.
