It occupies 2 modular width units (36 mm) on a DIN rail, with a depth of 76 mm and installation depth of 70 mm. The DC rating goes up to 72 V. This is the breaker you spec into a distribution board when you need the higher IEC 60947-2 fault-clearing margin for industrial panel coordination — the 30 kA rating means it can interrupt faults up to that level without cascading upstream, which is what makes it different from a residential-grade 6 kA-only unit. Width is 36 mm (2 MW), depth 76 mm, height 90 mm. Accepts solid conductors up to 35 mm². The dual breaking-capacity rating is the key spec: 6 kA per EN 60898 covers the residential and light commercial requirement, while 30 kA per IEC 60947-2 lets the breaker serve in industrial panels where fault currents are higher. The 2-pole configuration with 400 V AC multi-phase rating means it switches both phase conductors in a single-phase or two-phase circuit — common for 400 V line-to-line loads or sub-distribution. Mechanical life of 10,000 operating cycles is typical for this class; power loss of 1.3 W per pole at rated current matters for thermal budgeting in a densely populated enclosure.","metaTitle":"Siemens 5SN6204-7CP MCB, 2-pole, 400 V AC, 6 kA EN 60898","metaDescription":"Siemens SENTRON 5SN6204-7CP miniature circuit breaker, 2-pole, 400 V AC, 6 kA per EN 60898, 30 kA per IEC 60947-2.
