Frequently Asked Questions:

Q. How do I choose the correct circuit breaker for my needs?

A.

• Match the breaker's current rating to load demands.
• Ensure that the breaker's voltage rating suits the system.
• Select appropriate protection (overload, short circuit).
• Confirm the breaker's compatibility with use.
• Ensure that the breaker coordinates with other devices.

Q. What is the difference between a miniature circuit breaker and a moulded case circuit breaker?

A.

• Miniature circuit breakers are used for low to moderate current applications. They have compact size suitable for residential and commercial panels. These circuit breakers protect against overcurrents and short circuits.
• Moulded case circuit breakers are ideal for higher current and industrial applications. They are larger in size and are found in distribution boards and industrial settings. These circuit breakers offer adjustable trip settings with higher interrupting capacities.

Q. Does Raptor Supplies offer Square D circuit breakers with higher interrupting capacity?

A. Yes, customers looking for higher interrupting capacity varints can opt for Square D QO330VH circuit breaker having interrupting capacity of 22kA at 1220VAC & 240VAC.
