How do fuses and circuit breakers differ?

Fuses and circuit breakers both protect electrical appliances and circuits from short circuits and excessive current, but they work in different ways. Fuses are relatively low cost electrical safety devices.

When will Singapore end the circuit breaker?

As the daily number of new community cases has declined significantly and the dormitory situation has stabilised, Singapore is on track to end the Circuit Breaker on 1 June 2020. The risk of a resurgence in community transmission remains high, so Singapore must be cautious as circuit breaker measures progressively lift, over three phases.

How does a circuit breaker function?

A circuit breaker works by interrupting the flow of current when it detects a fault, such as a short circuit or an excessive amount of current. Unlike fuses, circuit breakers are resettable.

What happens when a fuse blows?

If too much current enters the circuit, the fuse will blow out, breaking the circuit and protecting the attached devices. This prevents electrocution and ensures that you can safely touch the devices. Once the fuse blows, it must be replaced before using the device or appliance again.

What happens when a circuit breaker trips?

When a circuit breaker trips, it interrupts the flow of current in the circuit. This happens when a fault is detected, typically a short circuit or an excessive amount of current. To reset the circuit breaker, simply flick the switch.
