Blue Sea Systems C-Series Toggle Circuit Breaker, Triple Pole, 120/240V AC, 80V DC, White Actuator

Overview

The Blue Sea Systems C-Series is a white triple-pole toggle circuit breaker range for AC main circuit protection and switching on boats. It combines a manual toggle switch with magnetic hydraulic circuit protection, giving one panel-mounted device for controlling and protecting three conductors in a marine electrical system.

These breakers are built for 120V AC, 240V AC, and 80V DC maximum voltage ratings, with a 5,000A interrupt capacity at 125V AC and 240V AC. In a 240V AC main breaker installation, the triple-pole format can switch both hot lines and neutral, and all poles trip together if any one pole trips.

The trip-free mechanism cannot be held in the ON position during a fault current condition. That matters on board because a breaker should open the circuit when a fault occurs, even if someone is holding the toggle.

Key features

• Triple-pole C-Series breaker for marine AC main protection and switching.
• Available in 50A, 60A, 80A, and 100A AC ratings to match the required circuit and conductor sizing.
• Magnetic hydraulic trip-free breaker type, so the toggle cannot override a fault trip.
• Rated for 120V AC, 240V AC, and 80V DC maximum system voltage.
• 5,000A interrupt capacity at 125V AC and 240V AC for high-fault-current protection in properly specified systems.
• All poles trip together when any one pole trips, helping disconnect the protected circuit in a controlled way.
• White toggle actuator suits many marine AC distribution panels and keeps operation simple at the panel face.
• 1/4-20 tin-plated brass terminal studs and #6-32 stainless steel mounting screws support marine panel installation.
• Operating temperature range from -40 degrees C to 85 degrees C for use across a wide range of onboard conditions.
• UL 1077 regulatory specification for supplementary circuit protection applications.

Variants

This C-Series triple-pole toggle breaker is offered in multiple amperage ratings. The pole count, white toggle format, voltage ratings, trip-free magnetic hydraulic construction, and 5,000A AC interrupt capacity remain consistent across these configurations.

The main selection point is amperage. Match the breaker rating to the protected circuit, conductor ampacity, and applicable marine electrical standards for the vessel.

• 7290, 100 Amp. This is the highest amperage option in this group and is suited to circuits specified for 100A AC protection.
• 7289, 80 Amp. This configuration fits installations that call for an 80A AC triple-pole breaker in the same white C-Series toggle format.
• 7288, 60 Amp. This option is for 60A AC circuits where a three-pole main or branch protection device is required.
• 7287, 50 Amp. This configuration matches 50A AC circuits and is commonly associated with marine 120/240V AC main protection layouts.

Installation and fit

This breaker is intended for panel mounting in a protected electrical distribution location. The terminal stud torque is 35 in-lb, and the mounting screw torque is 6 in-lb, so installation should be done with the correct tools and torque values rather than by feel alone.

Because the breaker is part of the vessel’s protection system, final sizing should account for conductor size, load type, continuous load, inrush current, and the rest of the AC distribution design. It is a good match for owners, technicians, and refit teams replacing or building a marine panel where a white triple-pole C-Series toggle breaker is already specified.

Marine use

On cruising boats, sportfishing boats, and larger sailboats with 120/240V AC service, a triple-pole breaker is used where both hot legs and neutral need to be switched together. The shared-trip behavior helps keep the circuit from remaining partially energized after a trip condition.

The white toggle is easy to operate at the panel, while the resettable breaker format avoids replacing fuses after a trip. As with any AC protection device, installation should be handled by a qualified marine electrician when the system layout, conductor sizing, or shore power configuration is uncertain.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
