Blue Sea Systems 7216 AC/DC Single Pole Magnetic Hydraulic Circuit Breaker - 25 Amp, 65V DC, Black

The Blue Sea Systems 7216 is a 25 amp, single pole magnetic hydraulic circuit breaker rated for AC and DC marine electrical systems, built to protect a single branch circuit from overcurrent damage. It uses a magnetic hydraulic trip mechanism rather than a bimetallic element, giving it a stable, repeatable trip point that does not drift with ambient temperature the way thermal breakers can. The breaker is trip free, meaning the switch cannot be held or pinned closed after it trips on a fault, so the circuit stays protected even if someone tries to force it back on.

As a single pole breaker, the 7216 is most commonly used for AC or DC branch circuit protection, matching individual loads to their own dedicated breaker. It is rated 25 amps at 65V DC and is built to operate reliably across a wide temperature range, from -40 degrees F up to 185 degrees F, and is designed for 10,000 switching cycles at rated amps and volts. Termination is made via a number 10-32 stainless steel terminal screw. The breaker carries UL 1077 (UL/CSA, US and Canada) and EN60934 (TUV, Europe) certification, confirming it meets recognized safety standards for circuit breakers used in marine and mobile electrical panels. Its black housing is intended for panel-mount installation as part of a Blue Sea Systems traditional metal power distribution panel.

Frequently Asked Questions

What is the amperage rating of the Blue Sea Systems 7216? The Blue Sea Systems 7216 is rated for 25 amps at 65V DC.

Is the 7216 an AC or DC circuit breaker? It is designed for AC/DC use as a single pole breaker, and single pole breakers like the 7216 are frequently used for AC or DC branch circuit protection.

How many poles does the 7216 breaker have? The Blue Sea Systems 7216 is a single pole (1 pole) circuit breaker.

What type of breaker mechanism does the 7216 use? Magnetic hydraulic technology is used in the 7216, rather than a thermal/bimetallic element, giving it a trip point that does not drift with ambient temperature.

Can the 7216 breaker be manually held closed after it trips? No. The 7216 is trip free, which means the switch cannot be held or forced closed after the breaker has tripped on a fault.

What color is the Blue Sea Systems 7216? The 7216 has a black housing.

What temperature range can the 7216 operate in? The 7216 is rated to operate from -40 degrees C (-40 degrees F) up to 85 degrees C (185 degrees F).

How many switching cycles is the 7216 rated for? 10,000 switching cycles at rated amps and volts is the rating for the Blue Sea Systems 7216.

What terminal connection does the 7216 use? A number 10-32 stainless steel terminal screw is used for wiring the 7216.

What safety certifications does the 7216 carry? The Blue Sea Systems 7216 is certified to UL 1077 (UL/CSA for US/Canada) and EN60934 (TUV for Europe).

How much does the 7216 circuit breaker weigh? The 7216 weighs 0.17 pounds.

What is the 7216 typically used for? The Blue Sea Systems 7216 is used as a single pole branch circuit breaker to protect an individual AC or DC electrical circuit from overcurrent.
