Product FAQs
7 answersWhat panelboards are compatible with the FDA32050 circuit breaker?
This breaker is designed exclusively for use in Square D I-Line power distribution panelboards and switchboards. It features an I-Line style plug-in connection that mounts directly to the bus assembly.
What is the modern replacement for the legacy FDA32050 circuit breaker?
For newer installations or when upgrading, the legacy F-frame FDA32050 is typically replaced by the Square D PowerPact H-frame series, specifically the HDA36050. The PowerPact H-frame offers the same 50A rating and I-Line mounting compatibility.
What wire sizes and materials are accepted by the lugs on the FDA32050?
The factory-installed lugs on this breaker accept either copper or aluminum (Cu/Al) conductors ranging from 14 AWG up to 1/0 AWG.
What type of trip unit is equipped on the FDA32050?
It features a non-interchangeable thermal-magnetic trip unit with fixed long-time and instantaneous (LI) trip functions. This provides standard overload and short-circuit protection for commercial and industrial applications.
Does the FDA32050 require separate mounting hardware for installation?
No, it utilizes an I-Line style plug-in connection. The breaker jaws plug directly into the panelboard bus, providing both the electrical connection and mechanical mounting without the need for separate fasteners.
Can the FDA32050 be used on 480V or 600V systems?
No, this specific FDA frame breaker is rated for a maximum of 240V AC. It provides an interrupting capacity of 25kA at 240V. For 480V or 600V applications, a different breaker series or frame is required.
Is the FDA32050 interchangeable with standard QO or Homeline breakers?
No. The FDA32050 is a legacy F-frame molded case circuit breaker designed specifically for commercial I-Line panelboards. It will not fit in residential QO or Homeline load centers.
