Product details

DC-rated miniature circuit breaker for industrial DC circuits

The B-curve (3-5 In) trips fast on moderate overloads, sized for 1 A continuous current. Mounts on a quick assembly system (DIN rail compatible), occupies 4 width units (72 mm wide), and accepts conductors from 0.75 to 35 mm² solid or stranded. Terminal torque spec is 2.5 to 3.5 N·m (22-31 lbf·in). Touch protection is built in; polarity must be observed on the supply cord. Halogen-free and silicon-free construction suits environments where outgassing or contamination is a concern — clean rooms, medical equipment, or food processing panels.

Mounting position is any. Sealable option available for tamper-proof applications. Tightening torque per the spec ensures reliable connection without strip-out.
