Description
Serving as a reliable drop-in solution for legacy systems, this single-pole 20A component mounts into Eaton Pow-R-Line 1a, 2a, and 3a panelboards. It eliminates the need for retrofit kits when servicing older commercial installations. Fully compatible with vintage Westinghouse enclosures, this unit is frequently cross-referenced with the newer HBAW1020 substitute. Carrying a robust 65kAIC rating at 120/240VAC, it maintains HACR and SWD certifications for switching duty applications.Specifications

Product FAQs
6 answersWhich panelboards are compatible with the HBA1020 circuit breaker?
This bolt-on miniature circuit breaker is designed for direct installation in Eaton Pow-R-Line 1a, 2a, and 3a panelboards, as well as legacy Westinghouse enclosures, eliminating the need for retrofit kits.
Is there a newer replacement or cross-reference for the Westinghouse HBA1020?
Yes, the HBA1020 is frequently cross-referenced with the newer Eaton HBAW1020. Both serve as direct drop-in replacements for legacy systems requiring a 1-pole, 20A bolt-on breaker.
How does the HBA1020 mount into the panelboard?
It utilizes a bolt-on mounting style, providing a secure mechanical and electrical connection directly to the panel bus. This ensures reliable performance in commercial and industrial environments.
What type of protection does the thermal-magnetic trip unit provide?
The fixed thermal-magnetic mechanism includes long-time and instantaneous trip functions. The thermal component responds to sustained overloads, while the magnetic component reacts immediately to short circuits.
What wire sizes are accepted by the terminals on the HBA1020?
The feed-thru box lugs accommodate wire gauges from 14 AWG to 4 AWG, providing flexibility for sizing conductors in 20A branch circuits.
Can the HBA1020 be used in high fault current applications?
Yes, it is suitable for systems with high available fault currents, providing an interrupting capacity of up to 65kAIC at 120/240V AC and 25kAIC at 480V.
