SQUARE D QO330 Miniature Circuit Breaker, 30A, 3 Pole, 120/240VAC, 10KA, Plug In Mount

Square D QO330 plug-in circuit breaker is used in commercial and industrial electrical distribution panels for safeguarding circuits against overcurrents and short circuits. This mini circuit breaker fits into QO load centres for overall equipment protection and prevents potential hazards due to electrical faults.

Working Mechanism:

• Current flows through closed breaker contacts.
• Excessive current triggers thermal-magnetic trip mechanism.
• Contacts separate, interrupting current flow.
• Rapid response shields the system from damage.
• Breaker can be manually reset after resolving the issue.

Features:

• This mini circuit breaker features an over centre, trip free toggle mechanism with quick make, quick break action and positive handle indication for ease of installation and operation.
• It has a VisiTrip indication for improved visual indication of tripped / interrupted circuit.
• This 3-pole QO circuit breaker is rated for 30A at 120/240VAC and offers 10kA breaking capacity.
• It comes with a plug in style mounting for easy and hassle free installation.

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.
