The Siemens 5SM1111-0FD is a Type AC FI-Protector (residual current device / RCD) rated 16A, 2-pole, with a 10mA rated residual operating current (IΔn) for 230V systems. The 10mA trip threshold makes it suitable for circuits requiring enhanced protection against earth faults — think wet areas, medical locations, or circuits feeding portable equipment where a standard 30mA RCD may not provide adequate personal protection. The 2TE (two module-width) footprint fits standard DIN-rail enclosures.
