Product FAQs
8 answersWhat type of equipment is the MAP36800 designed for?
This legacy MAP frame molded case circuit breaker is intended for use in vertical main configurations within Square D I-Line panelboards and standard distribution switchboards.
How are wire connections made to this circuit breaker?
The breaker features a feed-thru connection with factory-installed line and load side lugs. These terminals accept up to three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.
How does the adjustable magnetic trip function work?
While the thermal overload protection is fixed at 800 amps, the magnetic instantaneous trip setting can be adjusted. This allows electricians to fine-tune the breaker's short-circuit response to coordinate with downstream devices and prevent nuisance tripping.
Is the MAP36800 suitable for DC electrical systems?
Yes, in addition to its primary AC ratings, this thermal magnetic breaker is rated for 250VDC applications with a 14kA interrupting capacity.
What does the LI trip function specify for this model?
The LI designation means the internal trip unit includes Long-Time protection for sustained overloads and Instantaneous protection for immediate short-circuit fault clearing.
What safety indications are built into the MAP36800?
This breaker includes a visual trip indicator on the faceplate, allowing facility personnel to quickly visually verify if the breaker has tripped due to an electrical fault.
Can I use this breaker for commercial HVAC equipment?
Yes, the MAP36800 is HACR rated, making it fully certified for protecting heating, air conditioning, and refrigeration systems.
Can the MAP36800 be installed in any Square D panel?
No. While it is a Square D product, it is specifically designed as a bolt-on main breaker for I-Line panelboards and switchboards. It cannot be used in QO, Homeline, or other commercial panels that do not explicitly support MAP frame breakers.
