It switches the neutral conductor and is sealable — common for utility-metered sub-distribution where tamper evidence matters. ## C-curve selectivity and wire range The 20 A rating in C-curve means the magnetic trip fires between 100 A and 200 A; below that, the thermal bimetal handles overloads. Terminals accept 0.75…16 mm² solid or stranded copper, tightening torque 2…2.5 N·m (17.7…22.1 lbf·in). That wire range covers most final subcircuit conductors up to 4 mm² comfortably, with headroom for paralleled feeds if needed. ## Integration note Ambient -25…+45 °C, storage -40…+75 °C. Halogen-free and silicon-free construction, which matters for sensitive environments (clean rooms, food processing panels) where outgassing could contaminate optics or contacts.","metaTitle":"Siemens 5SL6020-7KL SENTRON MCB, 20 A C-Curve, 1P+N, 6 kA","metaDescription":"Siemens SENTRON 5SL6020-7KL miniature circuit breaker, 20 A, C characteristic, 1P+N, 6 kA breaking capacity per EN 60898.
