This is the part to specify when protecting power supplies, rectifiers, or control transformers that draw a low, steady current. The S800 series uses a modular 17.5 mm per-pole width, so this single-pole unit occupies one module space. Wire termination accepts copper conductors up to 35 mm² — sized for the full 15 A rating without derating on the terminals.","metaTitle":"ABB S801U-Z15 MCB S800 1P Z 15A, current lifecycle","metaDescription":"ABB S801U-Z15 miniature circuit breaker, S800 series, 1-pole Z-curve 15A.
