Siemens 3RV20111AA20 Motor Starter Protector 1.1-1.6A

Product Description

The SIEMENS 3RV20111AA20 is an S00 frame motor starter protector (MSP) rated for a current adjustment range of 1.1 to 1.6 amps. Motor starter protectors combine motor overload protection and short-circuit protection in a single compact device, eliminating the need for a separate fuse or circuit breaker ahead of the contactor. This unit is designed for use in industrial motor control circuits and is installed by licensed electricians and industrial controls technicians working on low-voltage motor branch circuits. Its compact S00 footprint makes it well suited for space-constrained control panels and enclosures.

This MSP is appropriate for small three-phase or single-phase motor applications where a current setting between 1.1 and 1.6 amps covers the full-load amperage of the motor being protected. Typical installations include motor control centers, machine control panels, and industrial automation systems requiring coordinated motor protection. The S00 frame size is among the smallest in the SIEMENS 3RV2 series, making this device a practical choice for protecting fractional-horsepower motors in light-duty industrial and commercial equipment.

Key Features

• Current adjustment range of 1.1 to 1.6 amps for precise motor overload protection
• S00 frame size for compact panel installation
• Combines overload and short-circuit protection in one device
• Eliminates the need for a separate upstream fuse on the motor branch circuit
• Compact footprint at approximately 4.724 inches long by 2.067 inches wide by 4.193 inches tall

Compatibility

Designed as an OEM-style motor starter protector for use in S00 frame motor control assemblies requiring a 1.1 to 1.6 amp overload setting.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC Article 430 requirements for motor branch-circuit protection. De-energize and lock out the control panel before mounting or wiring the device. Verify that the motor full-load amperage falls within the 1.1 to 1.6 amp adjustment range before setting the dial. Do not exceed the rated current setting for the motor being protected.
