Siemens 3RV20211GA15 Motor Starter Protector 4.5-6.3A

Product Description

The SIEMENS 3RV20211GA15 is a motor starter protector (MSP) in the S0 frame size, designed to provide combined motor protection and switching in a single compact device. It delivers adjustable overcurrent protection in the 4.5 to 6.3 amp range, making it suitable for protecting three-phase and single-phase motors in industrial control panels and motor control centers. Licensed electricians and industrial control technicians install this device as a primary motor branch-circuit protective component. The S0 frame size fits standard DIN rail mounting configurations used throughout commercial and industrial electrical systems.

This MSP is applied in industrial and commercial settings where motor branch-circuit protection is required without a separate circuit breaker and contactor combination. Typical installations include pump control panels, conveyor systems, HVAC motor control centers, and other motor-driven equipment. The 4.5 to 6.3 amp adjustment range suits small fractional to integral horsepower motors commonly found in light industrial applications. It is sold individually, one unit per pack.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the panel and verify absence of voltage before mounting or wiring the device. Secure the unit to a properly rated DIN rail and verify all load-side conductors are torqued per the terminal markings on the device. Set the current adjustment dial to match the full-load amperage of the protected motor before restoring power.
