Description

Engineered for space-saving performance, the Eaton A2020 tandem breaker delivers two 20A circuits from a single-pole footprint. It is ideal for residential upgrades where panel space is exhausted. This plug-on unit fits legacy Challenger and Type BR load centers. Featuring a non-CTL design, it installs into older panels and serves as an exact replacement for the BR2020. Rated 10 kAIC at 120VAC, this thermal-magnetic breaker provides reliable protection and is HACR and SWD rated.

Product FAQs

6 answers
What is the active catalog number for the Challenger A2020?

The legacy Challenger A2020 has been superseded by the Eaton BR2020. Both part numbers refer to the same non-CTL 20/20A tandem breaker design.

Are Challenger Type A breakers interchangeable with Eaton Type BR?

Yes. Eaton manufactures the Type BR line as the direct, UL-classified replacement for legacy Challenger Type A breakers. They share the same physical dimensions and plug-on mounting style.

Is the A2020 a CTL or non-CTL breaker?

The A2020 is a non-CTL (Circuit Total Limiting) tandem breaker. It lacks the rejection clip found on CTL breakers, allowing it to be installed in older panels that do not have notched bus bars.

How does the A2020 tandem configuration work?

It provides two independent 20-amp circuits from a single one-inch pole space. Both circuits draw from the same phase leg, meaning they cannot be used to supply a 240V multi-wire branch circuit or a 240V load.

Can the A2020 be used as a switch for lighting circuits?

Yes, it is SWD (Switching Duty) rated. This allows the breaker to be used for regular switching of 120V fluorescent lighting loads without damaging the internal contacts.

Does the A2020 meet requirements for HVAC equipment?

Yes, it is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that specifies HACR-type circuit breakers for branch circuit protection.
