Product FAQs

6 answers
What panels are compatible with the Wadsworth A210NI?

This breaker is designed exclusively for use in Wadsworth Type A load centers. It features a proprietary plug-on clip design that will not fit in modern panels from other manufacturers.

How does the A210NI connect to the panel busbar?

It uses a plug-on mounting style specific to Wadsworth Type A load centers. The breaker snaps directly onto the busbar stabs without requiring bolt-on hardware.

What applications typically require a 10-amp, 2-pole breaker?

A 10A, 240V breaker is typically used for dedicated, low-draw 240V equipment. Common applications include specific HVAC components, small motors, or specialized control circuits that require strict overcurrent protection.

Is Wadsworth still manufacturing new circuit breakers?

No, Wadsworth is a legacy brand and is no longer in business. Finding replacements requires sourcing original Wadsworth stock or using aftermarket UL-classified replacements, such as the Connecticut Electric UBIA series, specifically designed for Wadsworth Type A panels.

Does this breaker provide GFCI or AFCI protection?

No, the A210NI is a standard thermal-magnetic breaker providing only overload and short-circuit protection. It does not include Ground Fault or Arc Fault circuitry.

What does the NI suffix in the A210NI catalog number indicate?

The NI suffix stands for Non-Interchangeable. This was a design feature in older panels to prevent installing a higher-amperage breaker in a slot intended for a lower-amperage circuit.

    Breaker panel

    I recently purchased a breaker panel cover. It arrived in a timely manner well packed and unharmed.

    The shipping was free so I was sceptical.

    All is well.
