Product details

The DC coil is rated for 24 to 34 VDC, with a peak inrush current of 2.3 A.

This simplifies panel layout when space is tight. These are the minimum air gaps to maintain for safe operation and arc containment. These timing figures matter when coordinating with upstream protective devices or sequencing multiple contactors.

For BOM freeze or PCN watch, the SIRIUS series is a mature, widely deployed platform. Replacement or second-source options within the same size S00 family exist, but any substitution should be verified for coil voltage and auxiliary contact configuration.

Integration Notes for the Panel Builder

The screw terminals accept up to 4 mm² solid conductor, sufficient for motor circuits up to the contactor's rated capacity.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height is 58 mm, depth is 73 mm. Minimum clearance: 10 mm upwards, forwards, and downwards; 6 mm at the sides.

What conductor sizes does the screw terminal accept?

Solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² per terminal.

What is the coil voltage and type?

The coil is DC, rated 24 to 34 VDC. Peak inrush current is 2.3 A.

What is the mechanical life expectancy?

Typical mechanical life is 30 million operating cycles.
