Product FAQs
7 answersWhich panelboards and switchboards are compatible with the JLL36225 circuit breaker?
This unit mount breaker is designed for use in Square D NQ and NF panelboards, QED switchboards, industrial control panels, and motor control centers. It is not compatible with I-Line panelboards, which require a plug-in mounting style rather than lug connections.
What does the L in the JLL36225 catalog number indicate about its interrupting rating?
The L designates a high interrupting capacity tier within the PowerPacT J-Frame series. It provides an interrupting rating of 125kA at 240VAC, 100kA at 480VAC, and 50kA at 600VAC, making it suitable for systems with high available fault currents.
What wire sizes are accepted by the standard lugs on the JLL36225?
The standard line and load lugs accept aluminum or copper wire ranging from 3/0 AWG to 350 kcmil. Proper torque must be applied during installation to ensure a secure connection.
Can the JLL36225 circuit breaker be reverse fed?
Yes, standard unit mount PowerPacT J-Frame thermal magnetic circuit breakers with factory sealed trip units are suitable for reverse feeding applications.
How is the trip unit configured on this 225A breaker?
It features a thermal magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal protection is fixed, while the magnetic trip is adjustable to allow for precise short circuit protection coordination within your electrical system.
What is the difference between the JGL36225, JJL36225, and JLL36225?
They share the same physical dimensions and 225A thermal magnetic trip unit, but have different interrupting ratings. At 480VAC, the JGL is rated for 35kA, the JJL for 65kA, and the JLL for 100kA.
How does the handle indicate a tripped condition on the JLL36225?
The breaker handle features a three-position design. During a fault, the handle moves to a center tripped position, providing a positive visual indication that the circuit breaker has tripped before it can be reset.
