It occupies a single modular width (18 mm) on the DIN rail, making it a compact choice for residential or light commercial sub-distribution boards where branch circuit protection is needed on a 2-pole feed. The 4 A rating limits continuous load to about 920 VA on a 230 V single-phase leg or 1.66 kVA across both poles at 415 V. Rated for multi-phase operation up to 440 V AC and single-phase up to 250 V AC, the breaker covers both split-phase and line-to-line configurations. The 50/60 Hz frequency range is standard for global mains supplies. Snap-on DIN rail mount, any position. Depth is 76 mm, width 18 mm — one modular unit. The 70 mm installation depth accounts for the DIN rail clip and wiring space behind the panel. Sealable for tamper-proofing in metered or rental installations. Supplementary devices can be added — auxiliary switches, shunt trips, or alarm contacts — via the accessory slot on the right side.","metaTitle":"Siemens 5SL4204-7RC SENTRON MCB, 2P C 4A 10kA","metaDescription":"Siemens SENTRON 5SL4204-7RC miniature circuit breaker, 2-pole, C-curve, 4 A, 10 kA breaking capacity per EN 60898.

They share the same 10 kA breaking capacity at 415 V AC and the same 76 mm depth, but the 63 A unit has a higher power loss per pole (5 W vs 1.3 W). The 5SL4363-7 will not drop into a panel wired for the 4 A breaker without rewiring the busbar and load connections."},{"question":"What compliance documentation is available for the 5SL4204-7RC?","answer":"The 5SL4204-7RC is rated per EN 60898 (10 kA breaking capacity) and carries an IP20 protection class.
