Product Positioning

The 3RV2041-4KA10 is a SIRIUS 3RV2 series S3 frame motor protection circuit breaker with a current setting of 57~75A. It provides 10-level standard tripping characteristics and a standard breaking capacity of 65kA, and is suitable for general motor circuits.

Core Product Advantages and Features

Current setting 57~75A

With a rated operating current of 75A, the overload trip point can be finely adjusted according to the actual nameplate current of the motor, ensuring protection accuracy.

10-level standard tripping characteristics

It conforms to the IEC 60947-4-1 Class 10 tripping curve and is suitable for use with standard three-phase motors with normal starting time.

65kA breaking capacity at 400V

The maximum short-circuit breaking capacity Icu is 65kA and the operational breaking capacity Ics is 30kA at 400V, which meets the protection requirements of general power distribution systems.

Compact S3 framework design

The dimensions are approximately 165x70x176mm, and it supports 35mm DIN rail mounting, saving installation space in the distribution panel.
