Rated 15 kA breaking capacity per EN 60898-1 and 25 kA per IEC 60947-2, it handles fault currents up to 25 kA at 230 V AC — enough for most industrial panelboards with a transformer-fed supply. The DC rating of 15 kA at 60 V extends its use to DC auxiliary circuits, though the maximum DC operating voltage is 72 V.
The installation depth is 70 mm, and overall depth is 76 mm. The combined terminal at top and bottom accepts both busbar and wire connections, and the sealable design allows panel builders to lock settings after commissioning.
Halogen-free and silicon-free — important for clean-room or food-grade panels where outgassing can contaminate optics or electronics. The operating temperature range spans -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, dropping to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Compliant with IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077 / CSA C22.2 No.235. The UL 1077 supplementary protector rating is 5 kA — note that for UL-listed panelboards, this breaker is classified as a supplementary protector, not a branch-circuit protective device per UL 489. That distinction matters for North American installations: it can be used within a listed assembly but not as the sole branch-circuit overcurrent device.
