RoHS compliance is confirmed effective 01 June 2013, and REACH Article 33 candidate-list disclosure is on file. No UL or CSA listing is stated in the available data, so verify local code acceptance if the installation falls under a North American inspection jurisdiction. The 4-pole body occupies four modular width units (4 x 18 mm). Spring-cage or screw terminals accept copper conductors up to 25 mm², depending on the terminal variant — check the specific terminal marking on delivery. The D-curve characteristic means this breaker is sized for loads with repetitive high inrush, not for resistive heater banks where a B- or C-curve would be the better selectivity match.","metaTitle":"Siemens 5SL6404-8CC Miniature Circuit Breaker, 4-Pole D 4A 4","metaDescription":"Siemens 5SL6404-8CC miniature circuit breaker, 4-pole, D-curve, 4A, 400V, 6kA breaking capacity.
