Product details

Core specs and sourcing

Ambient temperature range during operation is -20 to +60 °C.

Any mounting position. Dimensions: 70 mm wide, 165 mm high, 176 mm deep. Screw-type terminals for the main circuit: accepts 2x (2.5…16 mm²) solid or stranded, or 1x (10…70 mm²) solid/stranded. Minimum side clearance: 30 mm; vertical clearance: 150 mm above and below.

Why this part for your storeroom

This is a current-production, widely used SIRIUS breaker — a critical spare for any panel with 3RV2-series motor starters. The 100 A rating and high interrupting capacity cover most medium-motor branch circuits. It's a fast mover, so keep one on the shelf for line-down situations.

Frequently asked questions

What are the key dimensions and mounting requirements?

Width 70 mm, height 165 mm, depth 176 mm. Mounts on 35 mm DIN rail with snap-on; any position. Allow 30 mm side clearance and 150 mm vertical clearance.

What conductor sizes does the screw terminal accept?

The main terminals accept 2x (2.5…16 mm²) solid or stranded, or 1x (10…70 mm²) solid/stranded.
