What amperage options are available for this circuit breaker?

This line is available in 15A (65V DC, part 7210) and 50A (80V DC, part 7244) single pole toggle versions, both with a white toggle.

How do I pick the right amperage for my circuit?

Match the breaker's amperage to the continuous current draw of the equipment and the ampacity of the wire gauge feeding it. Use the 15A breaker for lighter branch circuits and the 50A breaker for higher-draw circuits, referencing an ABYC-compliant wire and breaker sizing chart.

Is this a single pole or double pole breaker?

It is a single pole breaker. Single pole breakers are typically used for AC or DC branch circuit protection, as opposed to double pole breakers, which are typically used for AC main circuit protection.

What color is the toggle?

The toggle bat on both the 15A and 50A versions is white.

Can the breaker be held on during a fault?

No. Both breakers use a trip-free design, meaning they cannot be held in the ON position during a fault current condition; they will trip automatically to protect the circuit.

What type of breaker mechanism do these use?

Both use a magnetic hydraulic, trip-free circuit breaker mechanism that combines switching and circuit protection into a single device.

How many switching cycles are these breakers rated for?

Both are rated for 10,000 switching cycles at rated amps and volts.

What is the operating temperature range?

Both breakers operate from -40 degrees F to 185 degrees F (-40 degrees C to 85 degrees C).

Sizes & Options

Choose the amperage that matches the continuous load and wire gauge of the circuit you are protecting. The 15A breaker suits lighter branch circuits such as lighting, pumps, or electronics, while the 50A breaker is sized for higher-draw circuits like larger pumps, winches, or feeder lines. Always size the breaker to the wire and the equipment's rated draw, not the other way around, and consult your vessel's wiring diagram or an ABYC-compliant load chart if unsure.
