SQUARE D QO115 Miniature Circuit Breaker, 15A, 1 Pole, 120/240VAC, 10KA, Plug In Mount

Square D QO115 circuit breaker is ideal for safeguarding circuits from overloads and short circuits. It is used in garages & workshops, educational facilities, kitchens and bathrooms.

Working Mechanism:

• When an overcurrent event occurs, such as a short circuit or excessive current draw, the breaker's internal sensing mechanism quickly identifies the abnormal current surge.
• The sensing mechanism triggers the tripping mechanism within the breaker. This process involves the rapid movement of the paddle actuator.
• As the paddle actuator moves, the breaker's internal contacts are forced apart, effectively breaking the circuit and interrupting the flow of current.
• By opening the circuit, the breaker isolates the faulty section from the rest of the electrical system, preventing the overcurrent event from propagating further.

Features:

• This circuit breaker offers plug-in mounting style for straightforward installation and replacement within compatible electrical systems.
• It features a paddle actuator, providing a user-friendly mechanism for engaging and disengaging the breaker circuit.
• This circuit breaker is designed to be compatible with the QO Series panelboards and load centres, ensuring seamless integration within these designated electrical systems.
• This UL-listed circuit breaker accommodates wire sizes ranging from 14 to 8 AWG and has ambient temperatures up to 104 degrees F.
• It has a pressure plate terminal connection for a secure and reliable method to establish electrical connections within the circuit.

Frequently Asked Questions:

Q. How does the paddle actuator work?

A. The paddle actuator is the mechanism that controls the circuit breaker's opening and closing. When an overcurrent event occurs, the paddle actuator triggers the tripping mechanism, quickly opening the circuit to interrupt the current flow.

Q. What are the factors to consider while choosing a circuit breaker for my application?

A. Major factors include current rating, voltage compatibility, interrupting capacity, load type, wire sizes and panelboard compatibility.

Q. What is the interrupting capacity of this circuit breaker?

A. This Square D QO115 circuit breaker has an interrupt rating of 10kAIC at 120 / 240VAC.
