FAQ

 

Q1: Does this circuit breaker carry an HACR rating and can it be used for air conditioning equipment?

A1: Yes. The FD3100 features an HACR rating dedicated to HVAC applications. It can be directly installed for branch circuit protection of heating, air conditioning and refrigeration equipment, complying with power distribution standards for HVAC systems.

Q2: What circuit protection functions does the FD3100 offer?

A2: The FD3100 adopts a fixed thermal-magnetic trip design with dual protection functions. It provides delayed overload protection to prevent nuisance tripping during mild circuit overloads, plus instantaneous short-circuit protection that immediately disconnects power when a short circuit occurs. It delivers reliable safety protection for motor circuits and distribution branch circuits.

Q3: Are the mounting dimensions interchangeable among the FD3100, FD3080 and FD3125?

A3: Yes, they are fully interchangeable. The FD3080 (80A), FD3100 (100A) and FD3125 (125A) all belong to the Eaton FD frame series and share identical mounting dimensions and cutout sizes, differing only in rated current. Switch to the FD3080 for reduced load requirements or the FD3125 for distribution capacity expansion, with no cabinet modifications needed at all.

Q4: How can I place an order or apply for bulk purchase discounts?

A4: Send your required order quantity via email to Irene8866@163.com, or leave us a message on WhatsApp (+86 18950163907). We will reply within 24 hours with formal quotation and stock confirmation.
