Under UL 1077 and CSA C22.2 No.235 it's rated 5 kA, so if you're shipping to a North American job site, verify the available fault current at the panel doesn't exceed that. The 50/60 Hz rating covers both 50 Hz European and 60 Hz North American line frequencies. Single-phase supply voltage is 230 V AC; multi-phase and single-phase operation both go to 440 V AC. DC rating tops out at 72 V — useful for control circuits but not for a 125 V DC bus.
Environmental and mechanical notes
Ambient temperature range: -40 °C to 75 °C, with derating above 55 °C (max 95% RH at 55 °C, 55% at 70 °C, 35% at 75 °C). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Sealable, combined terminals top and bottom, and supplementary devices can be installed alongside.
