Product FAQs
7 answersWho manufactures the HH83XA550 circuit breaker for Carrier?
This breaker is manufactured by Heinemann and is often branded under Carrier or Carlyle for use in commercial HVAC equipment.
Is there a direct replacement for the 92A HH83XA550 in newer applications?
Yes, for newer applications, this 92A model is often replaced by the Carrier HH83XB405, which is an 88A version of the same breaker.
What does the 2 to 6 seconds L.R. trip time indicate on this breaker?
L.R. stands for Locked Rotor. This specific trip time allows the breaker to handle the high inrush current of a compressor motor for 2 to 6 seconds without nuisance tripping during startup.
What does the LI trip function provide on this breaker?
The LI (Long-Time, Instantaneous) trip function provides standard overload protection (Long-Time) and immediate short-circuit protection (Instantaneous) for HVAC circuits.
Why does this Carrier breaker use hydraulic-magnetic trip technology instead of thermal-magnetic?
Hydraulic-magnetic breakers are temperature stable. They do not derate in hot environments, ensuring precise and reliable protection for rooftop units and outdoor chillers regardless of ambient temperatures.
What type of HVAC equipment is the HH83XA550 designed to protect?
This 3-pole breaker is engineered for commercial Carrier chillers, heat pumps, rooftop units (RTUs), and other heavy-duty HVAC control panels.
How are wires connected to the HH83XA550 breaker?
This unit-mount breaker features stud and tapped pad terminals. It requires properly sized ring terminals or compression lugs to secure 3 AWG to 1 AWG conductors.
