Product details

Any mounting position allowed. Clearance: 50 mm upward and downward, 30 mm at the side, 0 mm forward or backward — tight side-by-side packing is possible as long as vertical spacing is maintained for heat dissipation. Requires a screwdriver with 3 mm shaft diameter and 3.0 x 0.5 mm tip. Strip length follows standard practice for spring-cage terminations.

Maximum switching frequency at AC-3 and AC-3e duty is 15 operations per hour. The circuit breaker is rated for a supply voltage range of 20 to 690 V.
