Siemens 3RV1011-0FA10 Motor Protection Circuit Breaker

Siemens 3RV1011-0FA10 Motor Protection Circuit Breaker is a compact three-pole motor protection device in the S00 size, designed for DIN-rail installation to protect small motors in control cabinets. Rated for up to 690 V AC (AC-3) with a Class 10 trip characteristic, it provides overload protection and features an adjustable A-release current from 0.35 to 0.5 A to suit light-to-moderate motor loads. The unit uses screw terminals, mounts on a DIN rail, and carries a front IP20 enclosure rating for standard cabinet environments; it supports phase disturbance recognition but does not include short-circuit-to-earth recognition or undervoltage release mechanisms. Typical applications include motor protection in industrial equipment such as conveyors, fans, pumps, and other small-to-mid sized motors where compact, integrated protection is desired and reliable tripping performance is required. As part of Siemens SIRIUS 3RV1 family, it integrates with other motor control components to form compact, modular protection schemes in modern control panels.
