Rated 16 A at 40 °C ambient, it carries that full rating up to 45 °C (still 16 A), then derates linearly to 11.2 A at 70 °C — a curve you need to check against your enclosure's internal temperature rise, especially in a crowded DIN-rail cabinet with heat-generating contactors or drives. ## DIN-rail fit and panel integration Installation depth is 55 mm, so it clears most 80 mm-deep enclosures with room for wiring behind it. Supply can enter from top or bottom, which simplifies busbar routing in multi-row panels. The IP20 rating applies only when the distribution board is installed with connected conductors — treat it as a panel-internal device, not for open or wet locations. Touch protection is finger and back-of-hand safe (IP2X equivalent). The panel door or front cover must be in place during maintenance.","metaTitle":"Siemens 5SM1111-6 SENTRON RCCB, 16 A, 10 mA, Type A, 2-Pole","metaDescription":"Siemens 5SM1111-6 SENTRON RCCB, 16 A rated, 10 mA trip, Type A, 2-pole, 10 kA SCCR.
