It's rated 25A, 2-pole, with a rated residual current (IΔn) of 0.3A at 230V, in a 55mm enclosure. At 2TE wide, this unit saves one module versus a separate MCB+RCD combination. The 0.3A sensitivity is for equipment and fire protection.","metaTitle":"Siemens 5SM1612-6FD FI-Protector Type A, 25A 2-pole 0.3A 230","metaDescription":"Siemens 5SM1612-6FD FI-Protector Type A (PSE/SSF), 25A 2-pole, 0.3A IΔn, 230V, 2TE.
