Terminals accept 0.75 mm² minimum to 25 mm² maximum — covers most branch-circuit wiring from 1.5 mm² lighting circuits up to 6 mm² feeder tails.
The 5SL4225-7CC ships as a single miniature circuit breaker with the terminal screws and cage clamps fitted. No separate busbar or accessory pack — the kit is complete for a single-pole-space install. Sealable with a lead seal wire through the housing eyelet for tamper-proof metering or critical circuits.
2-pole, C-curve, 25 A rated current at 400 V AC, 10 kA breaking capacity per EN 60898. Maximum operating voltage is 440 V AC for multi-phase operation. Rated for 50 Hz networks.

Both are 2-pole SENTRON MCBs on the same DIN-rail footprint with the same 36 mm width, so mechanical fit is identical. The 5SL6606-7YA is a 63 A B-curve device; the 5SL4225-7CC is 25 A C-curve. Rewiring is not required, but the lower current rating and different trip curve must be verified against the circuit's load and coordination study.
