RCBO stands for residual current breaker with overcurrent protection. The purpose of the RCBO is to monitor electric circuits and disconnect them when there is a fault in the circuit. It is extremely useful to provide protection against overload, short circuit, and earth leakage currents. At Meteor Electrical we provide a wide selection of curve types, phases, and amp ratings to meet the requirement of different installation needs.
Residual Current Breaker with Over-Current (RCBOs) protects against two types of faults and ensures the safe operation of electrical circuits. RCBOs are designed to do both the requirements of an RCB and MCB – providing protection for over-current and earth leakage.
How does RCBOs work?
RCBO are designed to disconnect/break the circuit if the circuit is unbalanced. It is used to protect against overloads, short circuits and earth leakage currents.
When would I use RCBOs?
RCBOs are commonly used in domestic industries to reduce the number of injuries caused by electric shock and offer protection for overcurrent. It is used to protect you and your electrical circuit
Can I fit RCBOs myself?
It is advised to hire an experienced and knowledgeable electrician to install the RCBOs to ensure safe installations.
What is the difference between RCBOs and RCDs?
RCDs are designed to protect you or your family from getting electrocuted. It detects the leakage of earth or any conductor. However is not an over-current device. Whereas, RCBOs are designed to offer both over-current protection and earth leakage protection.
What is the difference between MCBs and RCBOs
MCBs are designed to provide protection of the electrical circuit from damage from over-currents. However is not an earth leakage protection device. Whereas, RCBOs are designed to offer both over-current protection and earth leakage protection.
