Circuit Breakers

Having an effective and well-designed circuit protection system in every building is vital. It not only protects machinery and equipment from costly damage or even worse an electrical fire, but good circuit protection also ensures people are safe too.

Here, at RS we stock an extensive range of high-quality products within our circuit breaker range. They include various types of protection devices as well as consumer units, distribution boards and accessories. Whether you are designing and building a new system or maintaining an old one we have everything you need, providing the perfect end-to-end solution.

What are Circuit Breakers?

Circuit breakers are crucial electrical devices designed to automatically interrupt the flow of electricity in the event of an overload or short circuit. They serve as a safety mechanism to prevent electrical fires and protect equipment and individuals from potential hazards. By detecting faults in the electrical system, circuit breakers can quickly cut off power, thereby minimizing damage to wiring and connected devices. Their importance extends across residential, commercial, and industrial settings, ensuring electrical safety by preventing dangerous conditions that could lead to fires or equipment failure.

Types of Circuit Breakers

RCBO Breakers

RCBO stands for Residual Current Circuit Breaker with Over Current protection. Installed in consumer units they protect from short circuits, overload current and residual current as they combine all the functions of an MCB and an RCCB.

RCCB Breakers

RCCB stands for Residual Current Circuit Breaker. They are designed to quickly disconnect any enclosed circuit as soon as current leaks to the earthing wire. RCCBs are also effective in protecting from electrocution or shock from direct contact.

MCB Breakers

MCB stands for Miniature Circuit Breaker. They are designed to protect an electric circuit from overcurrent only. They do not safeguard people from electric shock caused by earth leakage.

MCCB Breakers

MCCB stands for Moulded Case Circuit Breaker. They are another type of electrical protection device used in higher current rating applications where a single MCB would not suffice. An MCCB protects against overload and short circuit faults. With its high breaking capacity and a wider range of current ratings, MCCBs are typically found in industrial systems rather than domestic systems.

Choosing the Right Circuit Breaker for Your Application

When selecting a circuit breaker, it’s essential to consider the specific requirements of your electrical system, including the type of environment, power capacity, and safety features needed. Below are key factors to guide you:

Application Needs

Residential circuit breakers are typically designed for lower power capacities and focus on safety features suitable for home environments, such as ground fault protection and arc-fault detection. In contrast, industrial circuit breakers are built to handle higher power loads and harsher conditions, offering enhanced durability and protection against more significant electrical faults, making them suitable for manufacturing and large-scale operations.

Industrial Applications

In high-power systems, circuit breakers must be capable of managing substantial electrical loads while ensuring durability and safety. It's crucial to select breakers with appropriate current ratings to prevent overloads, as well as features that provide overload protection to safeguard both equipment and personnel. This ensures that systems operate efficiently while minimizing the risk of electrical failures.

Panel Boards and Enclosures

Panel boards serve as the central hub for managing multiple circuit breakers, allowing for organized distribution of electricity throughout a facility. Enclosed circuit breakers, on the other hand, offer additional protection by housing the breaker within a durable enclosure, shielding it from environmental factors and physical damage. Choosing the right panel board or enclosure enhances safety and accessibility for maintenance.

Price and Availability of Circuit Breakers in the Philippines

When purchasing circuit breakers in the Philippines, the price can vary significantly based on the type, application, and specific features of the breaker. Here are the key considerations:

Pricing Factors: The overall price of circuit breakers can fluctuate due to brand reputation, technological features, and warranty options available in the Philippines.
Domestic vs. Industrial Applications: Circuit breakers designed for domestic use tend to be more affordable compared to those specifically engineered for industrial applications, which require higher durability and capacity.
Type of Breaker: Different types of breakers, such as single-pole, double-pole, and GFCI breakers, will have varying costs based on their design and functionality.
Current and Voltage Rating: Circuit breakers with higher current and voltage ratings generally come at a premium due to their enhanced capabilities and safety features.
