Accepts solid conductors up to 35 mm², so it can terminate larger feeder cables directly without a separate terminal block. Height is 90 mm, matching the SENTRON compact profile that leaves room for busbar bridging above. ## Temperature range and power loss Rated for ambient -40 °C to 75 °C, covering unheated electrical rooms and outdoor enclosures in most climates. Each pole dissipates 1.6 W in hot operating state at rated AC current — for a 2-pole unit that is 3.2 W total, negligible for thermal coordination in a crowded panel but worth checking if the enclosure is sealed and solar-loaded.","metaTitle":"Siemens 5SN6220-8CP MCB, 2-pole C-curve, 400 V AC, 6 kA","metaDescription":"Siemens 5SN6220-8CP 2-pole MCB, C-curve, rated 400 V AC / 72 V DC, 6 kA per EN 60898.
