Part of the PowerPacT J-Frame series, this 225A thermal-magnetic breaker delivers reliable LI protection for commercial and industrial applications. It installs into Square D switchboards, motor control centers, and industrial control panels using a standard unit mount configuration. Featuring an adjustable magnetic trip and a factory-installed 120VAC shunt trip, it provides versatile control and current-limiting performance up to 25kAIC at 240V.
What equipment is compatible with the JDP36225SA circuit breaker?
This unit-mount PowerPacT J-Frame breaker is designed for installation in Square D switchboards, motor control centers, and industrial control panels.
What does the SA suffix indicate on the JDP36225SA catalog number?
The SA suffix designates that this breaker comes with a factory-installed 120VAC shunt trip accessory. This allows the breaker to be opened remotely using a control voltage signal.
What are the wire size requirements for the JDP36225SA lugs?
The standard factory lugs accommodate aluminum or copper conductors with a wire range of 3/0 AWG to 350 kcmil.
What adjustability does the LI trip unit offer?
The thermal-magnetic trip unit features a fixed thermal element for long-time overload protection and an adjustable magnetic element for instantaneous short-circuit protection. This allows for precise coordination with downstream devices.
Are Schneider Electric and Square D JDP36225SA breakers interchangeable?
Yes. Schneider Electric is the parent brand of Square D, and PowerPacT J-Frame breakers are identical and fully interchangeable regardless of which brand name is printed on the label.
Is the JDP36225SA suitable for direct current (DC) systems?
Yes, this breaker is rated for DC applications up to 250VDC, where it provides a 20kA interrupting rating.
Does this breaker plug onto a busbar or require bolt-on connections?
The JDP36225SA is a unit-mount breaker, meaning it is designed to be bolted directly to the panel or enclosure backpan rather than plugging onto an I-Line bus connection.
