Product FAQs
7 answersWhat is the short-circuit interrupting rating for the JJP36150 at 240VAC?
This J-frame breaker has an interrupting capacity of 100 kAIC at 240VAC.
What type of electrical connections are standard on the JJP36150?
The letter P in the JJP catalog number indicates it comes with terminal nuts on the line side for fixed busbar connection and standard mechanical lugs on the load side (OFF end).
Which replacement lug kit fits the load side of this 150A breaker?
It uses the AL175JD standard lug kit, which accepts one aluminum or copper wire from 4 AWG to 4/0 AWG.
What are the magnetic hold and trip current values for this thermal-magnetic breaker?
The JJP36150 features a fixed magnetic hold current of 750A and a magnetic tripping current of 1500A.
Is the JJP36150 rated for 100% continuous current?
No, this is a standard 80% rated circuit breaker. Per the NEC, it should not be applied continuously at more than 80% of its 150A rating.
Can I install this breaker in a Square D I-Line panelboard?
No, the JJP36150 is a unit-mount circuit breaker designed for individual enclosures or standard backplate mounting. For I-Line panelboards, you need an I-Line specific J-frame breaker like the JJA36150.
Does this breaker include a manual testing feature?
Yes, all PowerPact J-frame breakers feature an integral push-to-trip button on the cover. This allows you to manually trip the breaker to verify the mechanical operation of the tripping mechanism as part of regular preventive maintenance.
