Blue Sea Systems 7290 C-Series Triple Pole White Toggle Circuit Breaker 100A

The Blue Sea Systems 7290 C-Series Triple Pole White Toggle Circuit Breaker is a heavy-duty, marine-grade 100-amp circuit breaker engineered for AC main circuit protection on boats, RVs, and other marine electrical systems. With a robust 5,000-ampere interrupt capacity, it meets ABYC requirements for 120/240-volt, 50-ampere main circuit protection.

This triple-pole breaker is designed to serve as a 240-volt AC main circuit breaker, simultaneously switching both line conductors (hot) and the neutral, providing complete circuit isolation in a single throw. Its magnetic-hydraulic design ensures accurate, temperature-independent tripping performance, while the "Trip Free" mechanism prevents the breaker from being held in the ON position during a fault condition—a critical safety feature.

Key Features:

• 100-amp rating — triple-pole configuration ideal for 240-volt AC main protection
• 5,000-ampere interrupt capacity meeting ABYC requirements for 120/240-volt 50-amp service
• Triple-pole design switches both line conductors (hot) and neutral simultaneously
• All poles trip together if any single pole detects a fault
• "Trip Free" design — cannot be held ON during a fault current condition
• Magnetic-hydraulic circuit breaker type for reliable, temperature-compensated performance
• Terminal Studs: 1/4 in.-20 tin-plated; maximum torque 35 in-lb
• Mounting Screw: #6-32 stainless steel; recommended torque 6–8 in-lb
• White toggle finish for clean, professional panel appearance
• VDE and CSA certified

The Blue Sea Systems C-Series circuit breakers are a trusted choice for marine electrical panel builders and installers seeking reliable overcurrent protection that meets industry safety standards.
