Product FAQs
7 answers
What type of enclosures or panels is the LHL36000M8041 compatible with?
This L-frame circuit breaker is designed for unit mount (feed-thru) installations and is compatible with standard Square D L-frame enclosures, switchboards, and industrial control panels.
Does the LHL36000M8041 provide thermal overload protection?
No. The M in the catalog number indicates it is a magnetic-only circuit breaker, also known as a motor circuit protector or automatic switch. It provides instantaneous short-circuit protection but requires a separate device for thermal overload protection.
What does the 8041 suffix indicate on this Square D circuit breaker?
The 8041 suffix indicates that the breaker comes equipped with factory-installed control wire tapped lugs on the terminals.
What wire size do the standard lugs on the LHL36000M8041 accept?
The standard AL400LA lugs for this 400A L-frame breaker accept one 1 AWG to 600 kcmil or two 1 AWG to 250 kcmil aluminum or copper conductors.
What is the interrupting capacity of the LHL36000M8041 at 240V and 600V?
In addition to its 35kAIC rating at 480V, this LH-frame breaker carries an interrupting rating of 65kAIC at 240VAC and 25kAIC at 600VAC.
Is the LHL36000M8041 rated for use in DC applications?
Yes, this breaker is rated for 250VDC applications with an interrupting capacity of 50kAIC.
Can I use the LHL36000M8041 to replace a standard LHL36400 thermal-magnetic breaker?
No. The LHL36000M8041 is a magnetic-only device without thermal overload protection. It cannot safely replace a standard thermal-magnetic breaker like the LHL36400 unless separate overload protection is provided in the circuit.
