Siemens Circuit breaker for transformer protection, screw, size S00

Product Overview

The Siemens 3RV2411-0JA10 is a 3-pole motor-protection circuit breaker (MPCB) from the SIRIUS 3RV2 series, designed for transformer and motor protection. Sized S00, it provides adjustable thermal overload protection (0.7 … 1 A) and magnetic short-circuit protection (instantaneous release at 21 A). The device is suitable for supply voltages up to 690 V AC and supports standard industrial switching capacity, with a short-circuit breaking capacity up to 100 kA. Compact and DIN-rail mountable, 3RV2411-0JA10 is ideal for protecting small motors, transformers, or control-circuit feeders in industrial installations.
