What is AB type circuit breaker?
Type B circuit breakers are designed to trip if the current flowing through hits between three and five times the recommended maximum or ‘rated load’. This is the most sensitive type of MCB, designed for domestic applications, and low voltage commercial settings where any current surges are likely to be small.
What’s the difference between AB and C type breaker?
Type B devices are designed to trip at fault currents of 3-5 times rated current (In). For example a 10A device will trip at 30-50A. Type C devices are designed to trip at 5-10 times In (50-100A for a 10A device).
What type circuit breaker do I need?
Circuit breakers have markings stamped on the side of them and are usually located inside the panel cover door. There is a label that will tell you what type of breaker is needed for installation in that particular panel.
What is B and C in MCB?
B Curve means the MCB trips between 3-5 times full load current. It is mainly used in residential applications where loads are resistive e.g. lighting fixtures, domestic appliances with low surge Levels. C Curve means the MCB trips between 5-10 times full load current.
