1. Product Name

SIEMENS 3RV2041-4FA10 Motor Protection Circuit Breaker (MPCB)

2. Product Introduction

The SIEMENS 3RV2041-4FA10 is a versatile motor protection circuit breaker from the Sirius 3RV series, designed to reliably protect motors against overloads, short-circuits, and phase failures. It combines thermal and magnetic tripping mechanisms in a compact, modular design, making it an ideal safety component for controlling and safeguarding ‌SIEMENS MOTOR‌ systems and other industrial drives.

3. Product Description 

The ‌SIEMENS 3RV2041-4FA10‌ is a high-performance motor protection circuit breaker engineered for the demanding requirements of modern industrial automation. Its primary function is to provide comprehensive protection for ‌SIEMENS MOTOR‌ applications by integrating both thermal overload protection and electromagnetic short-circuit protection within a single, space-saving device. The thermal protection element guards against sustained overcurrents that can cause motor winding damage, featuring an adjustable tripping threshold to match specific motor full-load currents. The magnetic trip mechanism offers instantaneous response to high-level short-circuit faults, ensuring rapid isolation to prevent catastrophic damage. This MPCB is characterized by its modular construction, allowing for easy addition of auxiliary contacts, alarm switches, and shunt trips to expand its functionality within a control cabinet. It supports direct mounting on standard DIN rails, simplifying installation and maintenance. Designed for operational reliability, it includes a "dual compartment" design that separates the power and auxiliary contact areas, enhancing safety and facilitating wiring. Its clear trip indication and manual ON/OFF/reset lever provide straightforward operation. Complying with international standards such as IEC/EN 60947, the 3RV2041-4FA10 is a robust and trusted solution for building safe, efficient, and controllable motor starter combinations, forming a critical protective interface between the power supply and the ‌SIEMENS MOTOR‌.
