At 36 mm wide (2 modular width units), it occupies two standard DIN-rail positions — a compact footprint that leaves room for additional devices in a crowded enclosure.
Breaking capacity and trip curve
Rated operational voltage reaches 440 V AC in multi-phase operation, and 250 V AC single-phase. DC rated voltage maxes at 72 V — useful for control-circuit tap-offs but not for high-voltage DC bus protection.
Snap-on DIN rail mounting, any position. Sealable design allows lockout/tagout. Halogen-free and silicon-free construction avoids corrosive off-gassing in sealed enclosures near sensitive electronics. Power loss per pole is 1.8 W at rated current in hot state — 3.6 W total for the 2-pole unit. Factor this into enclosure thermal calculations, especially when grouping multiple breakers in a small cabinet.
