It provides 3 kA breaking capacity (Icu) at 400 V AC, 50/60 Hz, certified to SANS 60947-2 — the standard governing low-voltage switchgear and controlgear in South Africa.
At 72 mm wide (4-pole format), it occupies 8 modules of 9 mm pitch on the rail. Ambient operating range is -5 to 60 °C; store between -40 and 85 °C.
Performance and compliance
Rated insulation voltage (Ui) is 500 V AC, with operational voltage (Ue) of 400 V AC. The service breaking capacity (Ics) equals 100% of Icu at 3 kA — meaning the breaker can be reclosed after clearing a fault at its full rating without degradation. Limitation class 3 per SANS 60947-2 indicates it limits let-through energy effectively, aiding downstream device protection. Suitability for isolation is confirmed, and the contact position indicator gives visual confirmation of open/closed state. Pollution degree 2 (non-conductive pollution only, occasional condensation) is typical for standard distribution panels. Electrical durability is 4,000 cycles; mechanical durability 10,000 cycles.
