Square D - JGL36225 225A 3-Pole 600V Feed-Thru Molded Case Circuit Breaker
Square D - JGL36225 225A 3-Pole 600V Feed-Thru Molded Case Circuit Breaker
Product images are representative only. Actual product may vary.
The Square D JGL36225 is a 3-pole, 225-amp thermal magnetic molded case circuit breaker (MCCB) rated for 600VAC with feed-through (feed-thru) mounting. Manufactured by Schneider Electric, the JG-frame design delivers reliable overcurrent and short-circuit protection for industrial and commercial main and feeder circuits. The feed-thru configuration allows the breaker to be wired from both the line and load sides, commonly used in service entrance and main distribution applications.

Frequently Asked Questions
What is the Square D JGL36225 circuit breaker?
The Square D JGL36225 is a 225-amp, 3-pole, 600V thermal magnetic feed-through MCCB used as a main or feeder breaker in three-phase commercial and industrial electrical distribution systems up to 600VAC.
What does feed-thru mounting mean for the JGL36225?
Feed-through (feed-thru) mounting means the circuit breaker accepts wiring connections on both the line (top) and load (bottom) terminals, making it ideal for use as a main breaker in panelboards where power flows through the breaker to downstream distribution.
What is the interrupting rating of the Square D JGL36225?
The JGL36225 has an interrupting rating of 65kA at 240V and 25kA at 600V, providing adequate fault current protection for most commercial and industrial power distribution applications.
