What does the specification of BS EN 60898 stands for?
BSI – BS EN 60898 – Specification for Circuit-breakers for overcurrent protection for household and similar installations | Engineering360.
What is the difference between MCB type B and C?
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). Type D devices are designed to trip at 10-20 times In (100-200A for a 10A device).
What is B and C Series 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.
What are Type B MCBs most suited for?
Miniature circuit breakers are classified to different types based on their tripping characteristics. Among these, Type B MCB are mainly used for low power domestic applications like lighting circuits, home wirings etc.
What does BS EN mean?
the British and European Standard Specifications

What type is a BS 60947 2?
BS EN 60947-2 (EN 60947-2, IEC 60947-2) relate to low-voltage circuit-breakers for use in industrial and similar installations. In the UK these are traditionally known as moulded case circuit-breakers (MCCB’s) or air circuit-breakers (ACB’s) according to the construction.
What is a BS EN 60947 2?
BS EN 60947-2 circuit-breakers Circuit-breakers to BS-EN 60947-2 are frequently used for industrial applications in utilities and manufacturing industries. They are used to protect power distribution circuits up to 1,000 V AC and 1500 V DC with current ratings of 0.5 A to 6,300 A.
What does C mean on circuit breaker?
Type C circuit breakers are used for more powerful electrical devices where any surges are likely to be higher – typically commercial and industrial environments. They are designed to trip at currents between five and ten times their rated load. Good examples include smaller electric motors and fluorescent lighting.
