MCB, RCCB, or MCCB: Which circuit breaker to choose?

A circuit breaker is an absolute necessity and one of the most significant safety devices in your home. Circuit breakers discontinue the power flow whenever there is an overflow of electric current in a building. Without circuit breakers (or fuses, which were used before some time), the electrical wiring in the household is futile because a simple wiring fault or equipment failures can cause fires.
Several types of circuit breakers are used in house wiring to protect it from the potential electrical hazards due to electrical overloads. The most widely used circuit breakers are Miniature circuit breakers (MCBs), Residual current circuit breakers (RCCBs) and Molded Case Circuit Breaker (MCCBs).
Here is the quick guide to the types of Circuit Breakers.

Miniature Circuit Breakers (MCB):
An MCB automatically switches off the electrical circuit during an overload as well as a faulty condition. MCBs have replaced fuses in a low voltage electrical network as they are much more sensitive to overcurrent than a fuse and are less dangerous to handle. An MCB is very simple, easy to use, and non-repairable, meaning an MCB is to be replaced in case it blows up once but fuses can be repaired after a small blow up too. This makes fuses more vulnerable to the trip but not an MCB.
Check out Havells range of MCBs in the rating from 0.5 A to 63 A and from Single Pole to Four Pole versions to meet the requirements at home, office and other places.

Residual Current Circuit Breaker (RCCB):
An RCCB is an electrical wiring device that senses leakage fault even in a low voltage circuit. RCCB, also known as Residual Current Device (RCD), contains a switch device that disconnects the circuit whenever the electric current leakage from one conductor doesn’t return back through neutral. An RCCB provides protection against earth leakage arising due to accidental human touch or insulation failures which an MCB doesn’t.
Havells has a range of best quality RCCBs in Double Pole and Four Pole versions, in different ratings, to meet different electrical requirements.

Molded Case Circuit Breaker (MCCB):
An MCCB will immediately interrupt when the electric current through it goes beyond a predetermined value. MCCBs are generally used with equipment with a high voltage such as generators, capacitors, motors, etc. The switching mechanism can be used to switch the circuit on or off for upkeeps and replacements.

Why choose Havells?

Havells is a pioneer in providing solutions that make our lives simpler, safe, and secure. Havells was a trailblazer in building a huge consumer portfolio in MCBs and RCCBs even when these were chiefly considered B2B categories with its chiefly “Shock Lagaa” campaign.

7 factors to consider before buying a ceiling fan

Buying the best ceiling fan for your room seems easy until you have to actually buy one. Whether you are buying a ceiling fan for your new home or just replacing the existing fan, you have to consider many factors before making the purchase. With several designs, sizes, and colors available, choosing the best-suitable ceiling fan is time-consuming. To make your buying process easy, here are the 7 factors you should consider before buying a ceiling fan for your home. Right size for your room: The first thing to consider is the fan size that fits your room. A wrong sized fan would not be able to efficiently cool your room. For instance, small ceiling fans or mini ceiling fans are mostly used in a kitchen or an attic and are not suitable for large rooms. Ceiling height: Along with the room size, you must also measure the ceiling height. This will help you determine how long of a down rod you’ll need. Ideally, a fan should be 7-8 feet above the floor.

Install quality electrical switches in your home

Switches play a significant role in our homes and now imagining a home without any electrical switches is not possible. They help us in accessing electrical devices by just a click. Being a great invention that allows us to use energy inflow, electrical switches also have to safe and secure to ensure that they don’t harm the people around them. Here are some of the basic features that the best electrical switch should have. The material: The first and foremost feature of the electric switches is the material which they are made of. So if this material is not right, then accidents might happen. Make sure that the switches you purchase for your home are made of certified plastic and blends. They should be shockproof, and ISI certified. The design: When you are sure about the foundation which is the material it is made of, make sure that your modular switches are sleek and match with the theme of your home. It is also essential as all the money you invested in making your home l

Learn comprehensively about submersible pumps and their benefits

Image
As inferred by the name, a 1hp submersible pump is designed to be positioned (submerged) in the water or other liquid that is to be removed. Submersible pumps are not all similar. There are diverse types of these mechanical devices, used in numerous applications, including borehole, pool, pond, well, fountain, bilge and sewage, etc.  If these pumps are so prevalent, then there must be some benefits of using them. What are these benefits? One benefit of a 1hp submersible pump is in the way it is designed. It is designed as a firmly enclosed unit, with waterproof gaskets and seals that keep the fluid out of the covering and interior constituents. This design warrants that the pump will not leak or short out electrically when it is under water. Besides being compactly sealed and water-resistant, there are other benefits of submersible pumps as compared to non-submersible models. One plus is how it pumps the water. The submersible uses straight pressure to shove the liquid via the
