Product FAQs
7 answersWhat legacy Square D breaker does the HDL36035 replace?
The HDL36035 serves as a direct replacement for the legacy FAL36035 molded case circuit breaker, providing an upgrade path for older 35A, 3-pole unit mount applications.
What is the required lug torque for the HDL36035?
The standard AL150HD mechanical lugs require a tightening torque of 44.3 lb-in (5 N.m) for 14 to 10 AWG wire, and 124 lb-in (14 N.m) for 8 to 3/0 AWG aluminum or copper wire.
What internal accessories can be installed in this 3-pole H-Frame breaker?
You can install up to two auxiliary switches (1A1B form C contacts) in a 3-pole PowerPacT H-Frame breaker. It also accepts one alarm switch (SD), one overcurrent trip alarm (SDE), and a shunt trip or undervoltage release module.
Is the HDL36035 suitable for reverse feed applications?
Yes, this PowerPacT H-Frame thermal magnetic circuit breaker is rated for reverse feeding.
How does the LI trip unit operate on this breaker?
The LI designation indicates that the thermal magnetic trip unit provides fixed Long-Time (L) thermal protection against overloads and fixed Instantaneous (I) magnetic protection against short circuits.
Can the HDL36035 be installed in an I-Line panelboard?
No, the HDL36035 is a unit mount circuit breaker designed for bolt-on installation in industrial control panels and switchboards. I-Line panelboards require a plug-on I-Line specific H-Frame breaker.
Does the HDL36035 include a manual testing feature?
Yes, it features 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 and connected auxiliary contacts.
