In a crowded enclosure or high-ambient panel, size the load circuit to the derated figure at the expected internal temperature. Mounts in any position (vertical, horizontal, inverted) and accepts supply from top or bottom. Installation depth is 70 mm plus the 77 mm overall depth. Touch protection is built in.","metaTitle":"Siemens 5SU1324-7KX20 SENTRON RCBO, 20 A, 10 kA, Type A, Cur","metaDescription":"Siemens SENTRON 5SU1324-7KX20 RCBO, 2-pole, 20 A rated, 10 kA (EN 60898) / 20 kA (IEC 60947-2), Type A residual current, curve C, IP20, current lifecycle.
