i-BREAKERS (MINIATURE CIRCUIT BREAKERS - MCB)

GUTS MCB (i breaker) is an economic series of electromagnetic device that automatically breaks the circuit if the current in the circuit reaches a predetermined value. The MCBS perform two major functions: over-current protection and short-circuit protection. The complete MCB system is housed within a plastic moulding which is made of flame-retardant, high strength plastic. The quality of the material used and its design ensures that the MCBs are highly durable and reliable.

i breaker MCBs are safe and useful in protecting people and property against electrical overload and short circuit risks, in homes, offices, factories and all types of business establishments. In the event of a Short Circuit, MCB disconnects supply to the load within a fraction of a second, and saves the life of a person exposed to the risk of electrical shock. MCBs are also highly useful in preventing electrical fires.

An MCB can be used instead of a conventional fuse in a distribution board. Compared to a traditional fuse, MCB are designed to operate accurately under both overload and short circuit conditions. An MCB can also be reset quickly after it trips. The tripping of MCB can easily be identified by its operating knob which moves from ON to OFF position.

SELECTION PROCEDURE

Now that you know about the types of MCB, you should analyze the kind that would best suit your household device. Before choosing the type of MCB, it is essential to find out a few technical details. First, check what voltage and frequency with which the device functions, load power demand like Lamps Max 100 W, Mixi-grinders 300w to 750W, Geysers-1500w - 2200W, Air Conditioners (ACS) 1500W to 2800W etc. Next, note the starting current load and trip characteristics. Additionally, see if there are any extra features like a manual or automatic reset and about safety approvals. Sometimes, the operating conditions, like the temperature, corrosion and radiation, may contribute to choosing the correct MCB. Although the current rating is the primary deciding factor, it is better to analyze other factors before investing in the MCB as it plays an important role in preventing electrical hazards at your place.
