Product FAQs
5 answers
What type of panels accept the JLA36225 circuit breaker?
It is designed for Square D I-Line panelboards and switchboards. The breaker features an I-Line plug-on design that connects directly to the panel bus stack, eliminating the need for line-side wire connections.
How is the JLA36225 secured into an I-Line panelboard?
The breaker plugs directly onto the bus stack using blow-on type line-side connectors. During installation, a flat-blade screwdriver is used in the mounting bracket notch to ratchet and fully seat the breaker against the bus bars. Finally, the retaining screw is tightened to the mounting pan.
What does the "L" in the JLA36225 catalog number signify?
The "L" indicates the interrupting rating tier for this PowerPacT J-Frame breaker. In this series, the L-rating provides a high interrupting capacity of 100 kA at 480 VAC and 125 kA at 240 VAC.
What are the wire size and torque specifications for the JLA36225 lugs?
The standard AL250JD load-side lugs accept aluminum or copper wire ranging from 3/0 AWG to 350 kcmil. The required tightening torque for these lugs is 225 lb-in (25 N.m).
What is the magnetic trip adjustment range for this breaker?
While the thermal overload protection is fixed at 225 amps, the instantaneous magnetic trip function is adjustable from 1125A to 2250A. This allows electricians to fine-tune the short-circuit protection based on specific load characteristics.
