Blue Sea Systems 7248 Circuit Breaker, 80 Amp Single Pole AC/DC, White, DIN Rail Mount

The Blue Sea Systems 7248 is an 80 amp single pole magnetic hydraulic circuit breaker designed for AC/DC circuit protection aboard boats and in other 12V/24V DC or 120/240V AC electrical systems. Its trip-free magnetic hydraulic mechanism means the breaker cannot be held closed against an active overload or short circuit, giving it a consistent, field-proven trip response rated for 10,000 switching cycles at its rated amperage and voltage. The white housing mounts to a standard DIN rail, simplifying installation into existing electrical panels and breaker banks without custom brackets or hardware.

This single pole configuration is built for straightforward DC circuit protection, and the same magnetic hydraulic circuit breaker family is also used for 120/240V AC circuit protection in double and triple pole configurations, where multiple poles are linked to trip together if any one pole trips. The 7248 carries a nominal operating voltage of 120/240V AC and a maximum operating voltage of 65V DC, and is rated to operate across a wide temperature range from -40 F to 185 F, making it suitable for exposed marine electrical compartments. At 0.36 pounds, it is a compact, panel-mount component intended for direct wiring into a DC circuit requiring 80 amp overcurrent protection.

Frequently Asked Questions

How many amps is the Blue Sea Systems 7248 rated for? The Blue Sea Systems 7248 is rated at 80 amps, in a single pole configuration.

Is the 7248 an AC or DC circuit breaker? It is a magnetic hydraulic breaker rated for a nominal operating voltage of 120/240V AC and a maximum operating voltage of 65V DC, so it can serve either AC or DC branch circuits within those ratings.

What color is this circuit breaker? The Blue Sea Systems 7248 has a white housing.

How is the 7248 mounted? It mounts to a standard DIN rail, so it installs directly into a DIN rail breaker panel without extra brackets.

What does trip-free magnetic hydraulic mean? It means the internal mechanism of the 7248 will trip on an overload or short circuit even if the switch handle is held or taped in the on position, unlike a simple thermal switch.

How many switching cycles is the 7248 rated for? Blue Sea Systems rates the 7248 for 10,000 switching cycles at its rated amps and volts.

What temperature range can the 7248 operate in? The breaker operates from a minimum of -40 degrees F to a maximum of 185 degrees F, suitable for marine electrical compartments exposed to temperature extremes.

How much does the Blue Sea Systems 7248 weigh? The 7248 weighs 0.36 pounds.

Is the 7248 single pole or multi-pole? The 7248 is a single pole breaker; Blue Sea Systems also offers double and triple pole versions in the same magnetic hydraulic breaker family for AC main and branch circuit applications.

What is the UPC for the Blue Sea Systems 7248? The UPC for the 7248 circuit breaker is 632085072483.
