Rated for 400 V AC (60 V DC per pole), it delivers a 25 kA breaking capacity per IEC 60947-2 at 400 V AC — enough to handle high-fault-current industrial feeds. Under UL 1077 it's rated 5 kA, so it qualifies as a supplementary protector for North American panels. The DC rating drops to 15 kA at 60 V, which covers most control-circuit DC buses.
The 15 kA DC rating at 60 V covers most 24 V and 48 V DC control circuits, but note the 72 V DC maximum operating voltage — don't exceed that on a DC bus. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, so it's fine on machine-mounted panels near conveyors or compressors. Temperature range spans -40 °C to 75 °C, with humidity derating: 95% RH up to 55 °C, 55% RH at 70 °C, 35% RH at 75 °C. That's broad enough for unheated outdoor cabinets in cold climates or near hot machinery. The sealable option allows locking the handle in the OFF position for lockout/tagout compliance.
Designed to IEC / EN 60947-2 and UL 1077, plus CSA C22.2 No. 235.
