Breaking capacity is 25 kA Icu and 25 kA Ics at 415 V AC 50/60 Hz — both ratings are equal, meaning the breaker can clear a fault at its full interrupting rating and be immediately reclosed without derating. This simplifies coordination studies in a 415 V distribution board. Rated operational voltage is 415 V AC, insulation voltage 750 V, and impulse withstand 8 kV — figures consistent with a Category A utilization breaker for distribution duty per BS EN 60947-2. The 2-pole configuration connects L2-L3 phases only, so it is not a full 3-phase disconnect. Panel-mounted on a backplate, accepts horizontal or vertical orientation.
Deployment Context
Intended for distribution applications — typically a branch circuit breaker in a 415 V AC panel feeding a single-phase or two-phase load (L2-L3). The toggle control type gives a visible on/off position for manual operation and lockout. Rated for 20,000 electrical cycles at rated current and 20,000 mechanical cycles — sufficient for a distribution breaker that sees infrequent switching, not a motor-starting duty cycle.
