Siemens 3RV2031-4WA10 Motor Protection Circuit Breaker

Product Positioning

The 3RV2031-4WA10 is a standard S2 frame motor protection circuit breaker with an overload range of 42...52A. It features Class 10 tripping characteristics, has no built-in auxiliary contacts, and is suitable for overload and short-circuit protection of general three-phase motor circuits.

Core Product Advantages and Features

Overload current adjustable from 42 to 52A

The rotary overload current setting corresponds to a motor rated current range of 42 to 52 amps.

Applicable motor capacity is approximately 45kW (400V).

Depending on the manufacturer's specifications, it can meet the protection requirements of three-phase motors with a power rating of approximately 45kW under 400V.

Transient short circuit trips 741A

When a short circuit occurs, the 741A trips instantaneously, quickly disconnecting the faulty circuit.

DIN rail or screw fixing

It can be installed using DIN rail quick-release or screw locking methods, offering high flexibility in the construction of the distribution box.
