Siemens 3RV20111GA15 Motor Starter Protector 4.5-6.3A

Product Description

The SIEMENS 3RV20111GA15 is a Size S00 motor starter protector (MSP) designed to provide overload and short-circuit protection for three-phase and single-phase motors in industrial control applications. With a current setting range of 4.5 to 6.3 amps, it protects motors operating within that load band without requiring a separate circuit breaker or overload relay. Licensed electricians and industrial controls technicians install this device in motor control centers, control panels, and direct-on-line starter assemblies where compact, reliable motor protection is required.

The 3RV20111GA15 is suited for light-duty motor loads in commercial and industrial environments. Its Size S00 form factor fits standard DIN-rail enclosures and Siemens contactor assemblies used in pump, fan, conveyor, and compressor starter circuits. The 4.5-6.3A adjustment range covers small fractional and low-horsepower motors commonly found in HVAC equipment, process machinery, and building automation systems.

Key Features

• Adjustable current range of 4.5 to 6.3 amps for precise motor protection
• Size S00 frame provides a compact footprint for space-constrained panels
• Combines overload and short-circuit protection in a single device
• DIN-rail mountable for standard industrial enclosure compatibility
• Compact dimensions of 4.016 inches x 1.929 inches x 4.016 inches

Compatibility

Designed as an OEM-style motor starter protector in the Size S00 class, suitable for use with compatible Siemens contactor and starter assemblies that accept S00-frame MSP devices on standard DIN rail.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the panel before mounting or wiring the device. Set the current adjustment dial to match the full-load amperage rating of the motor being protected before energizing the circuit. Do not exceed the rated current range of 6.3 amps on the protected motor circuit.
