SQUARE D HJL36040 Circuit Breaker, 40A, 3 Pole, 600VAC, 25KA, Lugs, Thermal Magnetic

Square D HJL36040 circuit breaker is suitable for industrial and commercial settings to ensure reliable circuit protection. It is used in electrical distribution panels to safeguard against overloads and short circuits. This circuit breaker is ideal for moderate power applications. It offers operational safety and minimises downtime for uninterrupted power supply within multiple installations.

Working Mechanism:

• Normal current flows through the breaker.
• Overload or short circuit causes excessive current.
• Thermal-magnetic trip mechanism activates.
• Thermal element heats, bending bimetallic strip.
• Arc chute action initiated, releasing trip latch.
• Contact separation interrupts current flow.
• Current disruption prevents further overload / short circuit.
• Rapid action protects connected devices.
• Breaker can be manually reset after issue is resolved.

Features:

• It features a thermal-magnetic trip mechanism that promptly responds to abnormal currents, preventing potential hazards and equipment damage.
• This HJL36040 circuit breaker uses electromagnet's and bimetal switch to detect electrical faults.
• This circuit breaker has an interrupt rating of 25kA and uses 4.5 inches of I-Line mounting space for ease of installation.

Frequently Asked Questions:

Q. Does Raptor Supplies offer Square D circuit breakers with higher amperage ratings?

A. Yes, Raptor Supplies offers Square D feed-thru circuit breakers with higher amperage ratings. Customers looking for such circuit breakers can opt for HJL36050, HJL26060 and HJL36070 circuit breakers having amperage ratings of 50, 60 and 70A, respectively.

Q. What factors should I consider while choosing a circuit breaker?

A.

• Load requirements and current rating.
• Voltage compatibility with system.
• Type of protection needed.
• Coordination with downstream devices.
• Environmental conditions and enclosure type.

Q. How do I install this Square D HJL36040 feed thru circuit breaker?

A.

• Turn off power to the circuit.
• Mount the breaker onto the panel.
• Connect incoming and outgoing wires to terminals.
• Tighten terminal connections securely.
• Test breaker functionality by restoring power.
• Close the panel cover to finish installation.

Q. What is the difference between a feed thru circuit breaker and a general purpose circuit breaker?

A. Feed thru circuit breakers are designed for wiring through the breaker, enabling connection to both sides for added flexibility, while general purpose circuit breakers provide standard protection without the through-wiring capability, suitable for typical single connections.
