Havells Air Circuit Breakers

The responsibility of the entire system falls upon bus couplers and main incomers. The speed, selectivity, and mechanical reliability of a fault interruption are critical when they occur at this level. Havells Air Circuit Breakers are provided for high current loads, where the stability of their performance, the repeatability of their operation, and their coordination with protection devices greatly affect the continuity of the plant.

Perfect Automation & Innovation supplies Havells Air Circuit Breakers to power control centers (PCCs) or main power distribution panels (MPDPs) where large loads are connected to them.

When selecting a circuit breaker for high current loads, the circuit breaker's breaking capacity must be compatible with the calculated fault level of the installation so that the circuit breaker will perform safely during the most severe conditions.

The adjustments to the protection settings on a circuit breaker are made to provide a co-ordination between the circuit breaker and the downstream molded case circuit breakers (MCCBs) or feeder circuits, which in turn reduces unnecessary downtime.

The design of the contact system in the circuit breaker allows for a long electrical and mechanical life; therefore, it will function reliably for frequent operation of load transfers and maintenance practices.

The construction method draws out allows for an efficient and effective means of isolating and replacing item without affecting the entire panel. Mechanical position indicator to indicate clear mechanical condition, which supports safe lockout procedures during servicing.

Solid busbar termination design allows for the handling of high current without temperature increase and continues to provide stable contact over time.

The option to add a shunt trip, under voltage release, motorize operation and communication modules allow for connections with automations and remote monitoring systems.

These Air Circuit Breakers can be found in use within Industrial Plants, Commercial Buildings, Utilities, and other Infrastructure Projects where reliable primary switching, fault protection and safe isolation of systems are necessary to provide continuous power supply.
