The 7.5 kA breaking capacity per EN 60898 tells you it can safely interrupt a fault current up to that level at the rated voltage; if your available fault current at the panel exceeds 7.5 kA, you need a higher-rated breaker upstream. Two poles (2P) on a 36 mm width (2 width units) means it occupies two adjacent DIN-rail slots in the enclosure. The 76 mm depth plus 70 mm installation depth leaves clearance behind the rail — standard for a 5SL6 family MCB. Wire range accepts 0.75 to 25 mm² solid or stranded, with a tightening torque of 2.5 to 3 N·m on the screw terminals. That covers most panel wiring from 1.5 mm² control circuits up to 25 mm² feeder tails. The terminals are touch-protected, and the breaker is sealable — useful for installations that require tamper-evident sealing after commissioning.
This MCB is designed for residential and infrastructure installations per EN 60898. It protects branch circuits in distribution boards, lighting panels, and small commercial sub-panels where the load is predominantly resistive or lighting with low inrush. The 63 A rating and 2-pole configuration suit single-phase or two-phase circuits up to 415 V AC.
