Breaking capacity sits at 10 kA per IEC/EN 60898-2 and UL1077, with a 15 kA DC rating under IEC 60947-2 — enough for most commercial and light industrial panelboards.
Rated 400 V AC (single- or multi-phase) and 440 V DC, with a maximum DC operating voltage of 500 V — so it covers 480Y/277 V panels on the AC side and common 440 VDC battery banks or UPS outputs. The 2-pole design switches both line conductors; neutral is not switched, which is correct for TN-S and TN-C-S systems where the neutral is bonded at the source. The 10 kA breaking capacity under EN 60898-2 is the standard for final circuits in most buildings; the 15 kA DC rating under IEC 60947-2 gives extra headroom for DC distribution where fault currents can be higher.
Depth is 76 mm (70 mm installation depth), so it fits flush in most 100 mm deep enclosures.
Ambient temperature range from -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, dropping to 35% RH at 75 °C). Vibration resistance tested to IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — survives the usual shipping and machine vibration without nuisance tripping.
