It carries a 63 A rated current and a 10 kA short-circuit current rating, with Type A fault current sensitivity — meaning it detects sinusoidal AC residual currents plus pulsating DC residual currents, covering the common fault profiles in mixed-load panels with electronics, drives, or rectifiers. At 65 °C it derates to 57.35 A, and at 70 °C to 48.84 A. The short-time delayed design (Type S / selective) provides coordination with downstream RCCBs, preventing nuisance tripping on transient leakage from connected equipment. Depth is 70 mm — check gland-plate clearance in shallow enclosures; the 90 mm height is standard for modular devices. Supply can enter from top or bottom — no orientation restriction.","metaTitle":"Siemens SENTRON 5SV3446-6LA01 RCCB, 63A 4P Type A, 10kA","metaDescription":"Siemens SENTRON 5SV3446-6LA01 RCCB, 63A rated, 4-pole, Type A, 10kA short-circuit rating.
