Q. What is a three pole circuit breaker used for?
A. A three pole circuit breaker is used to protect three phase circuits by disconnecting all three poles during overload or short circuit fault conditions.

Q. What current ratings are available?
A. This three pole circuit breaker is available in 10A, 16A, 20A, 25A, 32A, 40A, 50A and 63A ratings.

Q. What does the 6kA rating mean?
A. The 6kA rating refers to the breaker’s short-circuit breaking capacity. It is designed to interrupt fault currents up to 6kA within its rated application.

Q. What type of tripping curve does this breaker use?
A. It uses a C curve tripping characteristic, which is commonly used for general circuit protection applications where moderate inrush current may be present.

Q. Can this breaker be used with busbar connections?
A. Yes. It is applicable to terminal connection and pin/fork type busbar connection, making it suitable for compatible switchboard layouts.
