Description
A reliable solution for heavy-duty applications, this 150A, three-pole MCCB operates at up to 600VAC. It provides essential thermal-magnetic LI protection for commercial facilities. The unit-mount design fits into Square D switchboards and motor control centers. For future retrofits, this legacy L-Frame unit is replaced by the PowerPacT JGL36150. Featuring a 35 kAIC rating at 480V, it safely clears severe faults. The breaker is HACR rated and includes a push-to-trip mechanism.Specifications

Product FAQs
7 answersWhat types of equipment is the LHP36150MB compatible with?
This unit-mount breaker is designed for installation in Square D switchboards, motor control centers (MCCs), and individual enclosures.
What wire sizes do the standard lugs on the LHP36150MB accept?
The lugs can accommodate either a single 1 AWG to 600 kcmil wire or two 1 AWG to 250 kcmil wires per phase. They are compatible with both aluminum and copper conductors.
Is the LHP36150MB rated for use in DC electrical systems?
Yes, this breaker is rated for DC applications up to 250VDC, where it provides an interrupting capacity of 50kA.
What is the modern replacement for the legacy LHP36150MB?
The LHP36150MB is a legacy L-Frame breaker. For modern retrofits, it is typically replaced by the Square D PowerPacT JGL36150, though panel modifications may be required due to different physical dimensions.
Are the thermal and magnetic trip settings adjustable on the LHP36150MB?
No, this breaker features a thermal-magnetic trip unit with fixed long-time and fixed instantaneous (LI) protection. Neither the thermal nor the magnetic settings are adjustable.
How does the LHP36150MB mount into a panel?
It is a unit-mount, bolt-on circuit breaker. It is designed to be bolted directly to the mounting pan or busbar rather than plugging into an I-Line panelboard.
What are the AC interrupting ratings for the LHP36150MB at different voltage levels?
The breaker provides a maximum interrupting rating of 65kA at 240VAC, 35kA at 480VAC, and 25kA at 600VAC.
