The 400 V AC rating (440 V max with multi- or single-phase operation) covers most panel voltages; the 60 V DC rating (72 V max) lets it protect DC control circuits too.
At 54 mm wide (3 modular width units), 90 mm tall, and 76 mm deep (70 mm installation depth), it snaps onto standard DIN rail — any mounting position works, and the quick-assembly system means it clicks in without tools. The IP20 rating (with conductors connected) is typical for enclosed panel use; if you're pulling it for a field-service swap, the sealable design lets you lock the toggle position to prevent unauthorized toggling.
It carries dual certification to IEC / EN 60898-1 (the household MCB standard) and IEC / EN 60947-2 (the industrial breaker standard), so it's accepted across both residential and industrial panels. UL/CSA listing is also on file at 5 kA per UL 1077 / CSA C22.2 No.235. The part is halogen-free and silicon-free — no silicone outgassing to foul contacts in sealed enclosures. Vibration resistance per IEC 60068-2-6 is ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz, which covers most machine-mounted panels.
