Circuit Breakers: PR21-61F-3.00A-32269-2-V Application Field and Working Principle

Circuit breakers are used for a variety of reasons, such as preventing thermal overload, controlling short circuits, protecting current circuits from damage and protecting people from electric shock. The PR21-61F-3.00A-32269-2-V is one type of circuit breaker, developed and manufactured by ABB.

Application Field:

The PR21-61F-3.00A-32269-2-V is mainly used in industrial applications and buildings requiring a standardised electrical installation. It can be used in residential buildings as well as public places, such as shopping malls and buildings, hotels and restaurants, factories, offices and factories and industrial sites. This circuit breaker is suitable for applications requiring up to 690VAC and reliability is guaranteed thanks to its durability, contact accuracy and precision functionality.

Working Principle:

The PR21-61F-3.00A-32269-2-V circuit breaker uses a thermal-magnetic design to break the current circuit in the event of an overload. It is designed to sense excessive current and open the circuit instantly when an overload is detected. The thermal-magnetic design is also used to detect short circuit currents, which can then be cleared away from the system by breaking the circuit.The PR21-61F-3.00A-32269-2-V uses a mechanical action to activate the trip of the circuit breaker. The action of over currents, short circuits or other disturbances will cause a movement of the contact points and trip the circuit breaker. The trip mechanism then releases a spring behind the contacts, which releases the contact and opens the circuit.The PR21-61F-3.00A-32269-2-V also contains a voltage detector, which monitors the voltage of the system, and triggers the trip mechanism if the voltage exceeds a certain level. This allows the circuit breaker to protect the system from high voltages.

Conclusion:

The PR21-61F-3.00A-32269-2-V is a reliable and durable circuit breaker for medium electrical installations. It is designed to sense over current, short circuits and high voltages and break the circuit immediately when any of these conditions is detected. It is suitable for residential and industrial applications and provides protection from overloads and short circuits, as well as protecting people from electric shocks.
