SQUARE D EGB14030 Miniature Circuit Breaker, 30A, 1 Pole, 277 VAC, 65 KA, Bolt On Mount

Square D EGB14030 bolt-on circuit breaker protects electrical panels and distribution boards from overloads and short circuits. This electric circuit breaker is useful in commercial buildings, retail spaces and healthcare facilities.

Working Mechanism:

• During regular operation, when the current flowing through the circuit is within safe limits, the internal mechanism of the circuit breaker remains in a closed position, allowing uninterrupted electricity flow.
• If the circuit experiences an overload or a short circuit, the current spikes significantly.
• The circuit breaker's sensing mechanism detects this unusual current rise and reacts immediately.
• When an overload or short circuit is detected, the circuit breaker's internal tripping mechanism rapidly opens the circuit by moving the internal contacts apart.
• This action interrupts the flow of electricity, preventing further damage and potential hazards.

Frequently Asked Questions:

Q. How do I install a Square D circuit breaker?

A.

• First, turn off the main power supply.
• Then, select the appropriate slot in the electrical panel.
• Next, securely attach the breaker.
• Then, connect the wires.
• At last, switch the power back on.

Q. What do I do if a Square D circuit breaker keeps tripping?

A. If a circuit breaker repeatedly trips, it indicates an underlying issue such as an overload or a short circuit. To address this, you should unplug or turn off devices connected to the circuit, identify and rectify the cause of the overload or short circuit and then reset the breaker.

Q. What is the difference between a single-pole and a double-pole Square D circuit breaker?

A. A single-pole circuit breaker is designed to handle a single phase of electrical power, while a double-pole circuit breaker can handle two phases.

Q. What is the difference between a circuit breaker and a fuse?

A. A circuit breaker and a fuse both serve the purpose of protecting electrical circuits from overcurrent and short circuit conditions. However, a circuit breaker can be reset after tripping, while a fuse needs to be replaced once it is blown.
