Product FAQs
6 answersWhat does the YP suffix mean on the JJA36200YP?
The YP suffix indicates a factory-installed handle padlock attachment. This allows the breaker handle to be securely locked in either the ON or OFF position, which is essential for safe lockout/tagout (LOTO) procedures during maintenance.
What is the adjustable magnetic trip range for this 200A breaker?
While the thermal overload protection is fixed at 200A, the instantaneous magnetic trip is adjustable. The magnetic trip range for this specific J-frame breaker can be set between 1000A and 2000A to coordinate with your system's short-circuit requirements.
How is the JJA36200YP installed in a panelboard?
This breaker features an I-Line plug-on line connection that mounts directly onto the bus assembly of Square D I-Line panelboards and switchboards. The load side utilizes mechanical lugs that accept 3/0 AWG to 350 kcmil aluminum or copper conductors.
Can I adjust the continuous current rating on the JJA36200YP?
No, the continuous current rating is fixed at 200A. Because this breaker uses a thermal-magnetic trip unit, only the instantaneous magnetic trip threshold is adjustable. If you need adjustable continuous current, you must use a PowerPacT breaker equipped with a MicroLogic electronic trip unit.
What does the LI trip function code mean on this breaker?
The LI designation stands for Long-Time and Instantaneous protection. The Long-Time function provides thermal overload protection fixed at 200A, while the Instantaneous function provides magnetic short-circuit protection that can be adjusted between 1000A and 2000A.
Does the JJA36200YP include a push-to-trip feature?
Yes, it includes an integral push-to-trip button on the front cover. This allows electricians to manually trip the breaker to verify the mechanical operation of the trip mechanism prior to commissioning or during routine maintenance.
