Blue Sea Systems 7222 AC/DC Single Pole Magnetic World Circuit Breaker, White, 30 Amp
The Blue Sea Systems 7222 is a single pole AC/DC magnetic world circuit breaker rated for 30 amps, finished in white for panel mounting on boats and other 12V/24V DC or 120/240V AC electrical systems. It uses a magnetic hydraulic trip mechanism that is trip-free, meaning the breaker cannot be held closed by the operator once it has tripped on an overcurrent condition, protecting the circuit even if someone tries to force the switch back on. This design gives consistent, temperature-stable tripping performance compared to thermal breakers, holding its rated trip point across an operating temperature range of -40 F (-40 C) to 185 F (85 C).
The breaker mounts through a panel cutout using an included #6-32 stainless steel mounting screw, secured to a recommended torque of 6 to 8 in-lb, and terminates with a #10-32 stainless steel terminal screw for a corrosion-resistant connection. It is rated for 65V DC and 120/240V AC nominal operation, with a DC interrupting capacity of 7500 amps and AC interrupting capacity of 3000 amps and 1500 amps for a single pole breaker. Blue Sea rates the 7222 for 10,000 switching cycles at rated amps and volts, and it carries UL 1077 recognition along with CSA, CE, and TUV certification, meeting UL 1077, UL/CSA, and EN60934 standards for both North American and European installations. As a single pole breaker, it is intended for standard branch circuit protection rather than AC main circuit protection, which typically calls for a double pole breaker. It is part of a broader series of single pole panel-mount breakers offered in other amperage ratings and colors.

Frequently Asked Questions
What amperage is the Blue Sea Systems 7222 circuit breaker rated for? The 7222 is rated for 30 amps and is built as a single pole breaker, one of several amperage options in Blue Sea's white panel-mount world circuit breaker line.
Is the 7222 an AC breaker, a DC breaker, or both? It is rated for both: 65V DC and 120/240V AC nominal operating voltage, which is why it is marketed as an AC/DC world circuit breaker.
What does trip-free mean on this Blue Sea breaker? Trip-free means the 7222 cannot be held closed or reset by the operator while an overcurrent fault is still present, so the circuit stays protected even if someone tries to force the switch back on.
What is the operating temperature range of the 7222 breaker? Blue Sea specifies an operating range of -40 F (-40 C) up to 185 F (85 C) for the 7222 magnetic hydraulic breaker.
How is the Blue Sea 7222 mounted? It is a panel-mount breaker that installs with an included #6-32 stainless steel mounting screw, torqued to a recommended 6 to 8 in-lb.
What size terminal screw does the 7222 use? The 7222 terminates with a #10-32 stainless steel terminal screw.
What is the interrupting capacity of the 7222? As a single pole breaker, the 7222 has a DC interrupting capacity of 7500 amps and an AC interrupting capacity of 3000 amps and 1500 amps.
How many switching cycles is the 7222 rated for? Blue Sea rates the 7222 for 10,000 switching cycles at its rated amps and volts.
What certifications does the Blue Sea 7222 carry? The 7222 is UL 1077 recognized and CSA, CE, and TUV certified, meeting UL 1077, UL/CSA, and EN60934 standards for use in both North America and Europe.
How much does the 7222 circuit breaker weigh? The Blue Sea Systems 7222 weighs 0.17 pounds.
What color is the 7222 breaker and does Blue Sea offer other amperage ratings? The 7222 is finished in white and 30 amps; Blue Sea's same panel-mount series also includes single pole breakers in other amperages and colors, such as 25A, 40A, and 50A versions.
Is the 7222 a single pole or double pole breaker? The 7222 is a single pole breaker; double pole breakers in this family are typically used for AC main circuit protection instead.
