Blue Sea Systems 7353 C-Series Single Pole 20 Amp AC/DC Magnetic Hydraulic Circuit Breaker, White

The Blue Sea Systems 7353 is a single pole, 20 Amp magnetic hydraulic circuit breaker built for overcurrent protection on marine AC and DC electrical circuits. It combines the functions of a switch and a circuit protection device into one compact unit, letting you manually turn a circuit on or off while also protecting it from overload. The breaker uses a magnetic hydraulic trip mechanism rated for high interrupt capacity, making it suitable for use as main circuit protection as well as branch circuit protection.

A key safety feature of the 7353 is its trip-free design: once the breaker trips due to an overcurrent condition, the toggle cannot be held or forced closed to bypass the trip. This prevents a user from defeating the protection the breaker is meant to provide. The breaker is commonly used to protect circuits for inverters, bow thrusters, and windlasses, and is rated for both AC and DC applications within its stated voltage and amperage limits.

The 7353 features a white housing, a single pole toggle, and pole mount installation. It is rated for a maximum of 80V DC and up to 250V AC, with an interrupt capacity of 5,000A at 125V AC, 5,000A at 250V AC, and 10,000A at 80V DC.

Is the 7353 breaker compatible with both AC and DC systems? Yes, the Blue Sea Systems 7353 is compatible with both AC and DC systems for its stated amperage and voltage ratings.

How many poles does the 7353 circuit breaker have? It is a single pole circuit breaker with one switching toggle.

What is the maximum voltage rating of this breaker? The Blue Sea Systems 7353 is rated for a maximum of 80V DC and up to 250V AC.

What is the interrupt capacity of the 7353? Interrupt capacity is 5,000A at 125V AC, 5,000A at 250V AC, and 10,000A at 80V DC.

What color is the 7353 circuit breaker housing? The housing is white.

What type of trip mechanism does the 7353 use? It uses a magnetic hydraulic, trip-free mechanism, meaning the breaker cannot be held or forced closed after it trips.

What is the 7353 breaker commonly used for? It is frequently used to protect circuits for inverters, bow thrusters, windlasses, and other AC or DC marine electrical loads.

How much does the Blue Sea Systems 7353 weigh? It weighs 0.25 pounds.

How is the 7353 circuit breaker mounted? The 7353 uses a pole mount installation type.

What is included when you purchase the 7353? The Blue Sea Systems 7353 ships as a single circuit breaker unit.

Can the 7353 breaker be reset after it trips? The 7353 can be reset once the overcurrent condition clears, but its trip-free design prevents the toggle from being held or forced closed to bypass a trip while the fault persists.
