Siemens 3RV2032-4KA10 Motor Protection Circuit Breaker

Product Description

The SIEMENS 3RV2032-4KA10 is a motor protection circuit breaker designed to provide overcurrent and short-circuit protection for three-phase motor loads in industrial control panels. This device combines thermal-magnetic trip technology to guard motors against overload conditions and fault currents without requiring a separate overload relay. It is sized for use in motor starter assemblies and control cabinet applications. Licensed electricians and industrial maintenance technicians install this device as part of motor branch circuit protection in accordance with NEC requirements.

The 3RV2032-4KA10 is suited for industrial and commercial installations where motor branch circuit protection is required at the panel or in-line with a contactor. Typical applications include pump motor control panels, conveyor drive starters, compressor control assemblies, and other three-phase motor load circuits. The compact frame size fits standard DIN rail mounting, making it compatible with modular control cabinet builds.

Key Features

• Integrated thermal-magnetic trip for combined overload and short-circuit protection
• Designed for motor branch circuit protection without a separate overload relay
• DIN rail mountable for modular panel assembly
• Compact footprint suited for space-constrained control enclosures
• Single-pack quantity for straightforward per-motor installation

Compatibility

Designed as an OEM-style motor protection circuit breaker for use in three-phase industrial motor control and starter circuits.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC Article 430 governing motor branch circuit protection. De-energize the panel and verify zero voltage with a calibrated meter before installation or removal. Secure to DIN rail and verify all line and load terminal connections are properly torqued per the panel assembly requirements. Do not exceed the device's rated current or interrupt capacity.
