Siemens 3RV20110FA15 Motor Starter Protector 0.35-0.5A

Product Description

The SIEMENS 3RV20110FA15 is an S00-frame motor starter protector (MSP) rated for 0.35 to 0.5 amps. It combines manual motor switching, short-circuit protection, and overload protection in a single compact device. MSPs of this type are installed in industrial control panels and machine-control enclosures to protect three-phase and single-phase motors from damage caused by overloads, phase loss, and short circuits. The unit is sized for low-amperage loads, making it well suited for small fractional-horsepower motors and similar light-duty industrial drive applications. Licensed electricians and industrial controls technicians are the primary installers.

This device is used in industrial and commercial electrical control panels where motor branch-circuit protection is required. The S00 frame size fits compact DIN-rail assemblies and is compatible with standard S00-size contactor accessories and bus systems. Typical applications include conveyor drives, pump starters, fan motors, and other small motor loads requiring manual isolation and automatic overcurrent protection in a single unit. The 0.35-0.5A current setting range makes this part appropriate for the smallest motor loads in a panel lineup.

Key Features

• Integrated short-circuit and overload protection eliminates the need for separate fusing on qualifying circuits
• S00 frame size mounts on standard DIN rail for compact panel layouts
• Adjustable current range of 0.35 to 0.5A suits small fractional-horsepower motor loads
• Manual switching function allows local motor isolation during service
• Designed for use with S00-compatible contactor and accessory systems

Compatibility

Designed as an OEM-style replacement or new-installation MSP for S00-frame motor starter assemblies requiring 0.35-0.5A overload protection in industrial control panel applications.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC Article 430 and applicable local codes governing motor branch-circuit protection. De-energize and lock out the panel before installing or replacing this device. Verify that the current adjustment dial is set to match the full-load amperage of the motor being protected before energizing the circuit. Do not exceed the rated current range of the device when selecting it for a motor application.
