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.","metaTitle":"Siemens 5SM1111-0FD FI-Protector Type AC, 16A 2P 10mA 230V","metaDescription":"Siemens 5SM1111-0FD FI-Protector type AC, 16A 2-pole, 10mA rated residual current, 230V.
