What is the difference between the two A-Series toggle breakers?

The 7214 is a 20 amp breaker rated 65V DC in white, while the 7208 is a 15 amp breaker rated 32V DC in black. Choose based on the amperage and DC voltage of the circuit you are protecting.

How do I pick the right amperage for my circuit?

Match the breaker amperage to the current draw and wire gauge of the specific branch circuit, staying within the wire's safe ampacity. If your system runs at 32V DC or lower and needs 15 amps, choose the 7208; for 65V DC systems needing 20 amps, choose the 7214.

Are these single pole or double pole breakers?

Both are single pole breakers, used for AC or DC branch circuit protection. Blue Sea's double pole breakers are typically reserved for AC main circuit protection instead.

What type of circuit breaker mechanism do these use?

Both use a magnetic hydraulic, trip-free mechanism. Trip-free means the toggle cannot be held or forced to the on position while a fault current is present, so the breaker still protects the circuit during a fault.

What terminal do these breakers use for wiring?

Both terminate with a #10-32 stainless steel screw terminal.

How many switching cycles are these breakers rated for?

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

What operating temperature range do these breakers support?

Both are rated from -40 C (-40 F) up to 85 C (185 F), suitable for exposed marine electrical panels.

Does the toggle color indicate anything about the breaker rating?

Yes, Blue Sea uses color to help distinguish breakers at a glance within the A-Series line; in this line, white indicates the 20 amp/65V DC 7214 and black indicates the 15 amp/32V DC 7208.

Blue Sea Systems A-Series Toggle Circuit Breaker - Single Pole DC Circuit Protection, White and Black

$26.45

The Blue Sea Systems A-Series Toggle Circuit Breaker is a magnetic hydraulic, trip-free circuit breaker built for reliable branch circuit protection aboard boats. Each breaker combines a rugged toggle switch with a #10-32 stainless steel screw terminal, giving you a manual on/off switch and automatic overcurrent protection in a single compact unit. The trip-free mechanism means the toggle cannot be forced to stay on during a fault, so the circuit is always protected even under load. Rated for a wide temperature range and up to 10,000 switching cycles at rated amps and volts, this breaker is built to hold up to the vibration, moisture, and duty cycles typical of marine DC and AC branch circuits.
