Product Positioning

The Siemens SIRIUS 3RV2042-4RB10 is an S3 frame motor protection circuit breaker with a Class 20 trip rating and an adjustable current range of 65 to 84A, suitable for medium-sized motor applications with long start-up times.

Core Product Advantages and Features

Class 20 Long Start Protection

Class 20 tripping allows for a longer start-up time, preventing high-inertia motors from tripping accidentally.

Medium and high current coverage

The current is adjustable from 65 to 84A, covering the rated current requirements of most medium-sized three-phase motors.

Short circuit instantaneous jump rapid response

The N-release short-circuit instantaneous trip value is 1170A, which quickly disconnects the circuit when a fault occurs.

S3 frame robust structure

It adopts an S3 frame and screw terminals, which makes the structure stable and convenient for on-site maintenance and wiring.
