It occupies 2 module spaces (2TE) on a DIN rail and has a 55mm depth. ## Deployment context Snap-on DIN rail mounting for standard 35mm rail in distribution boards or sub-distribution panels. The 2TE width (approx 36mm) fits a standard modular enclosure slot. Rated for 230V AC line-to-neutral or line-to-line single-phase circuits where both poles need to be switched and protected — typical for final subcircuits supplying socket outlets, lighting, or small equipment in commercial and industrial installations.","metaTitle":"Siemens 5SM1312-6FD FI-Protector Type A, 25A 2P 30mA 230V","metaDescription":"Siemens 5SM1312-6FD FI-Protector Type A, 25A, 2-pole, 30mA rated residual current, 230V AC.
