Product details

Rated for a 30 A branch circuit, curve C response

Snaps onto DIN rail, fits standard distribution boards

DIN rail mounting per means this breaker clips directly onto a 35 mm top-hat rail inside a panel or enclosure. No tools needed for installation or removal — the latch releases with a screwdriver slot. The 3-pole footprint occupies three modular units (each 17.5 mm wide), so it fits standard 18 mm pitch distribution boards.
