Product details

Motor protection circuit breaker, 30 kA at 400 V

Trip Class 10 and phase failure detection

The 55 mm width fits a standard 6-module-wide slot in a panel. Any mounting position is allowed, which simplifies layout when the panel is tight on vertical clearance.

Screw terminals and conductor range

Screw-type terminals on the main circuit accept 2× (1 … 25 mm²) or 1× (1 … 35 mm²) solid or stranded copper. The M6 contact screws are standard for this class — torque them to the manufacturer's spec (not listed here) to keep the connection stable under vibration.

Current lifecycle — no obsolescence signal

Lifecycle stage is marked as current. This is an active catalog item in the SIRIUS line.
