Product Description
This motor protection circuit breaker is designed for reliable protection of three‑phase motors in industrial control panels. It supports operational voltages up to 690 V and provides thermal‑magnetic protection with a Class 10 trip characteristic, covering overloads and short‑circuit events. The unit features an adjustable thermal setting range from 11 to 16 A to match motor full-load current, and a 3‑pole configuration suitable for typical three‑phase applications. With a compact S0 frame, IP20 protection, and DIN rail screw or snap‑on mounting, it integrates cleanly into SIRIUS systems. Rated interrupt capacity is up to 50 kA, and mechanical dimensions are optimized for dense assemblies. Typical horsepower capabilities span up to 10 HP at 460 V and 15 HP at 575 V. The device offers robust surge and shock resistance for demanding environments. Use with compatible accessories and infeed systems where required. Model number: 3RV1021‑4AA10.
