Circuit Breakers

Circuit breakers are essential electrical safety devices commonly installed in distribution boards to protect electrical systems from overcurrent or short circuits. These safety devices also function as main switches to manually connect or disconnect power to a complete electrical sub-network. The primary purpose of a circuit breaker is to interrupt electricity flow when a fault is detected, preventing overheating, fires, and damage to connected equipment and individuals. Circuit breakers are must-have circuit protection systems that ensure that people and equipment are safe within buildings. 

Why Buy Circuit Breakers?

Buying circuit breakers is paramount for maintaining the safety and reliability of electrical systems. These devices offer automatic protection of valuable electronics, appliances, and occupants from potential electrical dangers. Their resettable functionality also translates to long-term savings and ensures compliance with safety standards. 

Circuit Breakers and Fuses: What's the Difference?

Both circuit breakers and fuses are circuit protection devices, but they operate differently. A fuse breaks the circuit permanently and requires replacements when blown. On the other hand, a circuit breaker temporarily interrupts the current flow and can be reused (reset) multiple times. Additionally, fuses are often used in simpler, low-cost applications compared to circuit breakers, which are used in complex or high-load environments.
