Circuit Breakers Singapore

Circuit Breakers

We carry a range of circuit breakers, for Singapore industrial and commercial purposes, with safe and reliable technologies. Circuit breakers are electrical switches that automatically interrupts the current of an overloaded electrical circuit, ground faults, or short circuits. It protects an electrical circuit from damaged caused by excess current.

Frequently Asked Questions

What is the difference between MCB and MCCB?

Ans: Miniature Circuit Breakers, known as MCB, and Molded Case Circuit Breakers, known as MCCB, are different in their applications. MCB is used for low voltage applications, typically in residential and commercial settings whereas MCCB is suitable for higher voltage and current ratings, often used in industrial applications.

How do I choose the right circuit breaker?

Ans: When choosing a circuit breaker, consider the following factors: Current Rating – the maximum continuous current it can handle without tripping; Voltage Rating – the maximum voltage it can safely interrupt; Interrupting Capacity – the maximum fault current it can safely interrupt; and Application Type – residential, commercial, and industrial use, determining the appropriate type and specifications.

What is the difference between a fuse and a circuit breaker?

Ans: A fuse is a single-use protective device that melts when excess current overloads the circuit, requiring replacement. In contrast, a circuit breaker protects against current overloads and short circuits, and can be reset and reused after tripping.
