Product Positioning

The 3RV2431-4BA10 is a model with a lower current range among the S2 size transformer protection circuit breakers in the SIRIUS 3RV2 series. Its A-operation overload range is 13...20A, making it suitable for protection of small-capacity transformer circuits.

Core Product Advantages and Features

Suitable for small-capacity transformer circuits

With an overload adjustment range of 13...20A, this is the lowest rated current model in the 3RV2431 series, suitable for small transformers.

Fixed ratio short circuit trip

The N-operation short-circuit trip value is 325A, and the trip current ratio relative to the rated value is higher than that of general motor protection circuit breakers, and it can withstand closing surges.

S2 casing standard specifications

It shares the same housing and mounting holes as the S2 size circuit breakers in the same series, which facilitates the standardized design of distribution panels.

Three-pole screw terminal

All three poles of the main circuit are connected with screw terminals, making installation and maintenance simple.
