Supply can enter from top or bottom — no forced busbar orientation. The 10,000 mechanical cycles typical service life is standard for a residual current device in this class — not a daily-switching contactor, but fine for the occasional test-button exercise and fault clearing it sees in service. Silicon-free construction matters for environments where silicone outgassing can contaminate contacts or optics. Overvoltage category III means it's rated for fixed-installation level (distribution board, not downstream socket).","metaTitle":"Siemens SENTRON 5SM3315-0KK RCCB, 2-pole, 125 A, 30 mA, 230","metaDescription":"Siemens SENTRON 5SM3315-0KK RCCB, 2-pole, type AC, 125 A, 30 mA, 230 V AC, 10 kA SCCR, DIN rail mount.
