Abstract

The interface card fixedly secured to the circuit breaker supplies information representative of the circuit breaker type and rating to a standard removable trip device. It comprises for example resistances designed to be connected in parallel to a resistance of a divider bridge defining in the trip device the instantaneous tripping threshold, modifying this threshold automatically according to the circuit breaker type and rating. The interface card can also supply the trip device with information representative of the rated current flowing in the primary winding of the current transformers fixedly secured to the circuit breaker.
