It's rated 230 V AC, 6 A, B-curve, with a 6 kA breaking capacity per EN 60898-1 and IEC 60947-2.
Snaps onto DIN rail (REG), 18 mm wide — that's one modular unit. Depth is 68.5 mm, installation depth 70 mm, so it fits standard distribution boards without a deep enclosure. Mounting position is any, which helps when you're packing a crowded panel. IP20 with connected protective device and conductors, so it's strictly for inside the cabinet.
Halogen-free and silicon-free construction, so it's suitable for environments where outgassing during a fault matters — think clean rooms or sensitive electronics nearby. Overvoltage category III, pollution degree 2, ambient temperature range -40 °C to 75 °C (55 °C with 95% RH). Mechanical service life typical 10,000 operating cycles. Supplementary devices can be installed on the side.
