The Square D HJP36060 is a 3 Pole thermal magnetic molded case circuit breaker with a current rating of 60 Amps and a voltage rating of 600VAC, 500VDC. It has an interrupting rating of 100kAIC at 240VAC, 65kAIC at 480VAC. The HJP36060 has a bolt-on connection type and includes long time and instantaneous trip functions.
Can I install the HJP36060 in a Square D I-Line panelboard?
No. The HJP36060 is a unit-mount breaker designed for individual enclosures or custom panels. For I-Line panelboards, you must use a PowerPacT H-frame breaker with an A connection type.
What does the P connection type indicate for the HJP36060?
The P connection type means this breaker is configured with terminal nuts on the line side and mechanical lugs on the load side.
What are the torque specifications for the load-side lugs?
The load-side lugs require 44.25 lb-in (5 N.m) for 14 to 10 AWG wire, and 123.91 lb-in (14 N.m) for 8 to 3/0 AWG wire.
Is the HJP36060 rated for 100% continuous operation?
No, this is a standard 80% rated circuit breaker. Per NEC guidelines, continuous loads should not exceed 48 amps, which is 80% of its 60A frame rating.
What is the interrupting capacity of this breaker at 600VAC?
While it provides 100kAIC at 240VAC and 65kAIC at 480VAC, the interrupting rating drops to 25kAIC when applied to 600VAC systems.
What is the difference between the HJP36060 and the HJL36060?
The difference is the termination style. The HJP36060 has terminal nuts on the line side and lugs on the load side. The HJL36060 is equipped with mechanical lugs on both the line and load sides.
Which replacement lug kit fits the load side of this breaker?
The standard mechanical lug kit for 15A to 150A PowerPacT H-frame breakers is the AL150HD, which accepts 14 to 3/0 AWG aluminum or copper conductors.
How can I manually test the mechanical linkage of the HJP36060?
All PowerPacT H-frame circuit breakers feature an integral push-to-trip button on the front cover. Pressing this button manually trips the breaker to verify the mechanical linkage is functioning properly.
