The DOMF01150 is a single-pole Domae miniature circuit breaker rated 50 A with a C curve (magnetic trip between 5 and 10 times In) and an Icn of 6000 A per IEC 60898-1. The C curve means it handles moderate inrush — typical for lighting, socket circuits, and small motor loads in commercial or residential panels — without nuisance tripping. The 6000 A breaking capacity is the standard domestic/commercial level; if your installation's prospective short-circuit current exceeds that, you need a higher-rated device upstream for selectivity. Thermal-magnetic trip technology combines a bimetal strip for overload protection (time-delayed) and a solenoid for short-circuit protection (instantaneous).
Clip-on mounting to DIN rail, 18 mm width (2 x 9 mm pitches), 81 mm height, 71.5 mm depth — standard modular footprint that fits any 1P slot in a Domae or compatible distribution board. Tunnel terminals accept 1–35 mm² rigid or 1–25 mm² flexible cable; strip length 14 mm, tightening torque 3.5 N.m. Comb busbar compatible, so you can feed multiple MCBs from a single supply bar without daisy-chaining wire.
