Introduction

Circuit breakers, or CBs, are electrical devices commonly used for the protection of electric circuits in power systems. A CB is designed to automatically disconnect a circuit when an over-load or a short-circuit occurs, thus providing much needed safety and reliability. The 4430.36 is one such CB, an electro-mechanical device with rated current up to 3200 amps. Let’s take a look at its application field and working principle.

Application Field

The 4430.36 can be used in high-voltage power systems and industrial systems, such as the emergency transport and distribution of electric power, industrial automation, traction applications and shipboard systems. It is mainly used for the protection of transformers, capacitors, gas and SF6 insulated switchgear, cables and motors.

Main Features

This CB has a rated current of 3200A and a breaking capacity of 105kA. It also has an operating voltage of up to 12kV. Its high speed of tripping and closing provides a fast response and reliable protection, safeguarding people, property and equipment. Moreover, the CB can be operated both manually and remotely.

Working Principle

At the heart of the 4430.36 are the closing coil and the tripping coil, which are responsible for the electrical interrupting function of the CB. When the CB is energised, the current will pass through the closing coil, creating a magnetic field that will pull the contacts of the CB inwards. When the contacts are closed, the circuit is closed, allowing current to flow. If an over-load or a short-circuit occurs, the CB will trip, cutting off the current flow in the circuit. This is done by the tripping coil, which also creates a magnetic field when energised. This field amplifies the effect created by the field of the closing coil, allowing the contacts to open rapidly and break the circuit.

Maintenance

The 4430.36 should be regularly maintained to ensure that it is functioning correctly. Since dirt and other contaminants can collect on the contacts and hinder their proper functioning, it is important to check these periodically. The CB contacts should also be inspected for wear and tear and corrosion, and the CB should be checked for loose connections and grounded parts.

Conclusion

The 4430.36 is a reliable and efficient circuit breaker with an impressive set of features and a wide application field. With its manual and remote operation, high voltage and breaking capacity, as well as its fast response, it is no wonder it is highly sought after in various power systems and industrial applications.
