Description

Belonging to the legacy MAP frame family, this 900A molded case circuit breaker provides robust thermal-magnetic protection. It mounts into older Square D panelboards utilizing bolt-on connections. Facilities upgrading can substitute this unit with a PowerPact P-Frame breaker, like the PGA36100, though a retrofit kit is required. Delivering a 30kA interrupting capacity at 480VAC, it includes factory-installed load side lugs and a visual trip indicator for quick status checks.

Product FAQs

6 answers
What type of enclosures is the MAP36900 designed for?

This legacy MAP frame breaker is engineered for bolt-on installation in older Square D panelboards and switchboards requiring 900A main or feeder protection.

What is the recommended modern replacement for the legacy MAP36900?

When upgrading or replacing this legacy MAP frame breaker, a Square D PowerPact P-Frame breaker, such as the PGA36100, can be used as a substitute. Note that a specific retrofit kit is required to mount a P-Frame breaker into older panelboards.

How does the trip adjustability work on the MAP36900?

This breaker utilizes a thermal-magnetic trip unit (LI) with a fixed thermal element for long-time overload protection and an adjustable magnetic element to fine-tune instantaneous short-circuit response.

How many conductors can be terminated per phase on the MAP36900?

The factory-installed lugs are designed to accept up to three 3/0 AWG to 500 kcmil aluminum or copper conductors per phase.

How can I identify if the MAP36900 has tripped?

The breaker features a built-in visual trip indicator, allowing maintenance personnel to quickly verify the breaker status during a fault condition without manually testing the handle position.

Is the MAP36900 suitable for direct current applications?

Yes, this breaker is rated for use in DC electrical systems up to 250VDC, where it provides a 14kA interrupting capacity.
