Square D JDL26200 Molded Case Circuit Breaker

The JDL26200 is a unit-mount circuit breaker. It features a feed-thru design with lugs on both the line and load sides, allowing it to be bolted directly to a backpan or mounting plate in industrial enclosures, switchboards, and control panels.

This breaker features a thermal-magnetic trip unit with a fixed thermal rating of 200A and an adjustable magnetic trip. The instantaneous magnetic trip threshold can be adjusted via a dial from a low setting of 1000A to a high setting of 2000A to coordinate with downstream loads.

The JDL26200 comes standard with AL250JD mechanical lugs, which accept 3/0 AWG to 350 kcmil aluminum or copper wire. These lugs should be torqued to 225 lb-in (25 N.m) for a secure connection.

In the Square D PowerPacT J-frame nomenclature, the "D" indicates the interrupting capacity tier (25kA at 240VAC, 18kA at 480VAC, and 14kA at 600VAC). The "L" indicates that the breaker is a unit-mount configuration with lugs on both the line and load ends.

No, the JDL26200 is a unit-mount breaker designed for backpan installation. For an I-Line panelboard, you will need the I-Line version of this breaker, which typically has a catalog number starting with JDA depending on the required phase connection.

Yes, standard Square D PowerPacT J-frame thermal-magnetic breakers like the JDL26200 have sealed trip units and can be reverse fed. They do not have line and load side restrictions unless equipped with specific accessories that dictate flow direction.

Yes, this breaker is HACR rated, meaning it is certified for use with heating, air conditioning, and refrigeration equipment that requires group motor protection.
