The Advantages and Disadvantages of Square D RCBOs

When installing a circuit breaker, the electrician must determine which type is an ideal option. That is because it provides security for many devices in your home. RCBOs are responsible for protecting circuits against the residual current, in other words, earth leakages. Also, the other feature of the RCBOs is protection from overcurrent. It performs the dual function of a Miniature Circuit Breaker (MCB) and Residual Current Device (RCD).

Square D RCBOs

The RCBOs that Square D makes are becoming more and more famous among circuit breakers. And using these Square D RCBOs hugely benefits both the users and the producers. It is also among the most resilient, quick, and secure circuit breakers in the market. Square D produced an amazing RCBO based on years of experience. The circuit breaker uses all of the most recent features while retaining all of the previous ones.

Here are some of the benefits and disadvantages of using RCBOs by Square D.

Benefits of Using Square D RCBOs

  • Square D’s RCBOs provide the same security as a single MCB and RCD. But usually at a lower cost.
  • The key benefit is that if an electric failure occurs, a circuit breaker will trip. But unlike other circuit breakers, it will only trip one circuit. And there will be no cases of an entire region losing power.
  • As a result, when a circuit trips and there is a power cut, the electrician will be able to locate it much quicker. And this is because the electrician will already identify a single circuit as the source of the problem.
  • In terms of commercial use, it is not easy to fuel an entire building from the main supply. Square’s RCBOs are able to supply electricity to a massive number of devices installed in the building. It does that by putting less strain on the machines as well as the users.
  • The RCBO is an excellent way to protect against the excess current consistently.
  • Additionally, the lack of multiple circuit breakers decreases significantly, resulting in a shorter installation time. And it does not require much space.
  • It has a long lifespan. The RCBOs will last for at the very least 2000 operations.

Disadvantages of Using Square D RCBOs

  • The RCBOs are on the more expensive side due to their high quality. Depending on the type, a single-pole can cost up to £70 – £74. But for a one-time investment, it is definitely worth the price.
  • Type B or Type C RCBOs are widely available. But if an electric motor overtrips, it will leave you with a separate MCB or an RCD. A Type D RCBO will not suffice. Square D’s RCBOs are mainly for residential and commercial use.

Different Variants of RCBOs by Square D

Square D RCBOs consist of circuit breakers with single pole Type B, Type C and Type K trip curves, similar to the Square D MCBs. The single-pole RCBOs are 19mm in width.

The trip rating is 16 Amp, and every single unit has a tripping capacity of 30mA, which is the most popular range among RCBOs.
