1 year warranty
The Siemens 3RV1742-5JD10 is a 3-pole molded-case circuit breaker from the SIRIUS 3RV17 family, frame size S3, designed for plant and system protection in industrial applications. It is UL 489 and CSA C22.2 No. 5-02 approved, making it suitable for use as a branch circuit breaker in North American panels. The device features a fixed thermal overload (A) release set at 50 A and a fixed electromagnetic short-circuit (N) release at 650 A, providing both overload and short-circuit protection. It uses screw terminal connections and offers standard switching capacity. Typical applications include protecting feeders, distribution circuits, transformers, and motor branches in machine-tool, OEM, and industrial control panels. The device is DIN-rail or screw mountable and integrates with the broader SIRIUS modular system, including auxiliary contacts, shunt trips, and undervoltage releases.
