Robust overload protection is now affordable with Himel MCCB

MCCB or the Molded Case Circuit Breaker is installed to protect the components of an electrical circuit from overload or short circuit fault currents. The device comes with a wide range of current ratings up to 2500 Amps and frequencies thus making it useful for both low and high voltage operations.

Let us dive in a little deeper as to how a Molded Case Circuit Breaker functions. To start with the built, the MCCB has a frame—the molded case that houses all the components. The frame has a compact design and is made up of materials having high dielectric strength. The size of the case and the breaker’s characteristics such as the voltage and current ratings determine the ratings of the MCCB.

The critical component however is an arc chute or arc extinguisher that contains an arrangement of mutually insulated and parallelly stacked steel plates. The arc is extinguished by splitting and lengthening arc. The quenching of arc and tripping of the MCCB is obtained by the tripping units which are the bimetallic strips for thermal tripping and the short circuit tripping due to the magnetic fields created because of the high currents through the solenoid valves. 

How important are Molded Case Circuit Breakers?

Let’s take an example of an incident where the operations team had multiple sources of raw power to deal with, out of which only one source could be made through to run the entire system. In case of a failure, the other source would get activated and things would again be brought back to normal once the power was restored. The team could make this happen without fuss just by tailoring MCCB as per requirement. Hence MCCB are central to seamless operations, especially at a bigger scale.

Installing Himel MCCB ensures overload protection and electrical fault protection against short circuit currents

Himel MCCBs are not only cost efficient but also offer more value per dollar spent. With different specifications available, the correct selection of MCCBs becomes easier for diverse applications which is crucial to providing adequate protection in sites with high-power equipment.

Space Management

The Himel MCCBs are compact and easy in terms of space. Along with it, the freedom to install it either vertically or horizontally saves a considerable amount of space in the electrical panels and feeder pillars.

Durable and lesser downtime

By automatically interrupting the current Himel MCCBs protect your electrical systems from damage caused by short circuit and overload. With rigorously tested product design, this switching happens in no time and reduces downtime during fault conditions.

Longer lifespan

Himel MCCBs are built to deal with high current and heavy-duty applications. The flexibility and add-on installations in it such as the adjustable trip settings enable a lower inventory and longer lifespan of the product.

Wide range of Applications

MCCBs can be used for controlling industrial plants and power stations. It protects transformers, capacitors and generators. They can be installed in places of potential explosion or fire hazards.

Advanced Communication Capabilities

Himel MCCB opens doors for new possibilities in industrial operations. After a faulty condition, one need not do anything extra to re-power the electrical circuit. The only thing one needs to do is press the close button of MCCB.

More options of accessory mounting

To increase the functionality of a Molded Case Circuit Breaker, accessories are mounted to suit unique power protection requirements. The Himel range of MCCBs have arrangements for all accessories such as the under-voltage release, voltage trip, alarms, auxiliary contacts, etc.
