Series Overview
Series Overview
- 3RV6/3RV5 circuit breakers are compact - type motor starting protection circuit breakers. They can be used for the switching on/off and protection of three - phase induction motors (with a maximum power of 45kW at an AC voltage of 400V) and other loads (with a maximum rated current of up to 100A).
- 3RV6/3RV5 circuit breakers are suitable for any climate and are applied in the normal operating environment of enclosed spaces (such as dust - free, free of corrosive gases or harmful gases). When installed in dusty and humid places, appropriate protective covers need to be equipped.
- 3RV6/3RV5 circuit breakers can have wires connected from the top or the bottom.
- For the ambient temperature allowed by the circuit breakers, the maximum breaking capacity, the tripping action current, and other conditions, refer to the specific technical data and tripping characteristic curves in this chapter.
- 3RV6/3RV5 circuit breakers can be used in IT systems (IT networks), but the different short - circuit breaking capacities in IT systems should be taken into account.
- Even for motors with the same rated power, due to the instantaneous peak current, their operating current, starting current, and current peak value are all different. Therefore, the rated value of the motor in the selection table can only represent guide data. The actual rated data and starting data of the motor are very important for selecting a suitable circuit breaker. This principle also applies to circuit breakers for transformer protection.
