ABB Electrical S2C-H6RU Miniature Circuit Breaker

ABB Electrical S2C-H6RU Miniature Circuit Breaker

Basic information

Series: Belongs to ABB's S200 series of miniature circuit breakers, which are renowned for their reliability and compact design.

Meaning of model number: S2C denotes its series model number, the H in H6RU may denote a specific function or feature, the 6 denotes a relevant parameter such as rated current, and the RU denotes a relevant configuration such as its auxiliary contacts.

Functional characteristics

Overload and short-circuit protection: when the current in the circuit exceeds a certain multiple of the rated current, the bimetal in the thermal release mechanism will be bent by heat and trigger the release to cut off the circuit; when a short-circuit fault occurs and the current increases sharply, the magnetic release mechanism will act quickly to trip the circuit breaker to protect the line and equipment safety.

Auxiliary contact function: Equipped with auxiliary contacts, it can be used to indicate the status of the circuit breaker, such as whether it is closed or not, and can also be used for interlocking control with other control circuits or equipment.

Technical Parameters

Rated voltage: suitable for AC 50/60Hz, rated voltage 230/400V circuit environment.

Rated current: rated current is 6A, can meet the general small load or branch circuit protection needs.

Breaking capacity: with a certain short-circuit breaking capacity, it can reliably cut off the circuit during short-circuit faults to ensure the safety of the system.

Applications

Industrial field: In the production line of factories, it can be used to protect all kinds of small motors, control circuits, lighting equipment, etc., to prevent equipment damage and production interruption due to overload or short circuit.

Commercial places: such as shopping malls, supermarkets, office buildings and other places in the lighting system, socket circuits, air conditioning systems and other power distribution protection, to ensure the stability and safety of power supply.

Civil housing: used in the family socket, lighting circuit protection, etc., to protect the residents of electricity safety, to prevent electrical failure caused by fire and other accidents.
