66565-4 is a contact-multi purpose type of self-proving electric circuit breaker, designed to provide short circuit and overload protection of electricity service within buildings.

This type of circuit breaker is suitable for residential, commercial and industrial installations. It can protect against short circuit and overload of up to 110 V AC and 250 V AC. It is also capable of keeping electric wiring safe from damage due to circuit misalignment and arcing.

A typical electric circuit breaker operates in a very simple and straightforward manner. This type of breaker is made up of two main components: the contacts and the tripping mechanism. When the current exceeds the rated value, the tripping mechanism trips the circuit breaker and interrupts the circuit.

The contacts of the66565-4 contact multi purpose self-proving electric circuit breaker are made from a combination of metals including copper and silver. The combination gives the contact greater flexibility and improved protection against heat, arc flash, and electric arcs. This combination also makes it more resistant to corrosion.

The tripping mechanism of the66565-4 contact multi purpose self-proving electric circuit breaker works on the principle of air pressure. When the pressure rises above a certain limit, the contacts close quickly in order to securely shut off the electric circuit. Air pressure is created by the movement of the contacts and is regulated by the use of springs.

The66565-4 contact multi purpose self-proving electric circuit breaker is capable of providing a reliable and secure electric circuit protection. It is suitable for a wide range of applications, including residential, commercial, and industrial. Its tripping mechanism is designed to offer fast and efficient operation, ensuring that the circuit breaker will stay on and the electric circuit will remain safe even under extreme conditions.

The66565-4 contact multi purpose self-proving electric circuit breaker is a reliable and durable device which meets all relevant safety standards. It is easy to install and requires minimal maintenance. With its superior design and features, it is an important part of any electrical system.
