Product FAQs
7 answersWhat types of electrical equipment is the Square D MAL36600 designed for?
This breaker is commonly installed in Square D switchboards, motor control centers, and standalone industrial enclosures.
Which replacement lug kit is compatible with the MAL36600?
The AL900MA mechanical lug kit is the standard replacement for this breaker frame. It accommodates three conductors per phase, accepting 3/0 AWG to 500 kcmil aluminum or copper wire.
How does the thermal magnetic trip unit operate on the MAL36600?
It utilizes a fixed thermal element to protect against standard overloads and an adjustable magnetic trip to allow fine-tuning of the instantaneous short circuit protection threshold.
Can I adjust the standard overload threshold on this breaker?
No, the long-time thermal trip function is fixed at 600 amps. Only the instantaneous magnetic trip threshold can be adjusted on this specific model.
Does the MAL36600 use a plug-on or bolt-on mounting configuration?
It is a unit mount, bolt-on circuit breaker. It requires a hardwired feed-thru connection and is not compatible with Square D I-Line plug-on panelboards.
Can this breaker be used in DC voltage applications?
Yes, the MAL36600 is rated for use in 250VDC systems and carries an interrupting rating of 14kA at that voltage, providing flexibility for industrial DC installations.
What frame family does the MAL36600 belong to?
It is part of the Square D legacy M-Frame molded case circuit breaker lineup. This series is utilized in high-capacity distribution systems requiring dependable thermal magnetic protection.
