Product FAQs
5 answersIs the MAP36500 compatible with standard plug-on I-Line panelboards?
The MAP36500 is a bolt-on circuit breaker designed specifically for use as a vertical main in Square D I-Line panelboards and switchboards. It does not feature the plug-on jaw connections used for standard I-Line branch breakers.
What are the wire size requirements for the MAP36500 lugs?
The factory-installed lugs accept up to three aluminum or copper conductors per phase, accommodating wire sizes from 3/0 AWG up to 500 kcmil.
How do the trip settings work on the MAP36500?
This breaker features a thermal-magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal overload protection is fixed at 500 amps, while the magnetic instantaneous trip is adjustable to coordinate with downstream loads and prevent nuisance tripping during inrush currents.
Is the MAP36500 a current production breaker?
The MAP36500 is a legacy Square D M-Frame circuit breaker. It is typically sourced as a direct replacement for existing vertical mains in older switchboards, whereas new installations generally use the modern PowerPact M-Frame series.
Does the MAP36500 include ground fault protection?
No, this breaker is equipped with an LI (Long-Time, Instantaneous) trip unit. It does not have the integrated ground fault (G) protection required for certain main breaker applications.
