T Tocas E9 200A Manual-Reset Circuit Breaker 3/8" Studs IP67 Waterproof, 12–48V Protection

The T Tocas E9 is a reusable 200-amp manual-reset DC circuit breaker built for heavy-duty automotive, marine, and off-grid electrical protection.

Compact but rugged, the E9 200A breaker combines high interrupt ratings, ignition protection, and a weatherproof housing so you can protect winches, battery banks, chargers, and high-current accessories without swapping fuses. Designed to meet SAE, J1171, and UL1500 specifications, this switchable breaker covers 12–48V systems and resets instantly with a simple flip—no tools or replacement fuses required.

How does the E9 protect high-current accessories?

The E9 interrupts dangerous overloads and short circuits up to its interrupt rating, preventing wiring damage and equipment failure. It’s built to safely clear faults on heavy loads like winches and inverter inputs while minimizing downtime.

• 200A continuous rating with 2,500A interrupt at 14V and 1,500A at 48V
• Meets ignition protection standards SAE J1171 and UL1500 for engine-bay installs
• Manual Type III reset for immediate restoration after trip

Is this breaker durable enough for marine and outdoor use?

Yes — the E9 uses a UL 94V-0 flame-retardant plastic shell and IP67 sealing to resist water ingress and harsh environments. It’s rated to operate across a wide temperature range suitable for engine compartments and exposed installations.

• IP67 waterproof rating for temporary immersion protection
• Operating range from −32°C to 82°C to handle varied climates
• Protective cover and corrosion-resistant studs for long service life

How easy is installation and reset?

Installation is straightforward: the E9 uses 3/8"-16 stainless studs compatible with common ring terminals, and an extended surface mount that keeps the breaker secure. After a trip, restore power instantly by flipping the manual reset switch — no fuse changes or spare parts required.

• 3/8"-16 threaded studs for standard hardware and ring terminals
• Surface-mount design with included protective cap for terminals
• Manual reset switch eliminates fuse replacements and reduces downtime

Can I use this with my 12V, 24V, or 48V systems?

The E9 is specified for DC systems from 12V up to 48V, making it versatile for vehicles, boats, and off-grid setups. Check the system voltage and continuous current draw to confirm the 200A rating matches your application needs.

• Rated for 12–48V DC systems including automotive and marine
• Use for winches, inverters, battery banks, and charging circuits
• High interrupt ratings suitable for inductive loads and starters

Who is this for? Technicians, DIYers, fleet managers, and boat owners who need a reliable, reusable circuit breaker for high-current DC circuits will appreciate the T Tocas E9. It’s well suited for anyone installing or protecting heavy loads—winches, audio systems, chargers, inverters, and other 200A-class circuits—especially where environment resistance and ignition protection are required. Choose the E9 when you want a durable, serviceable protection device that reduces downtime and eliminates constant fuse purchases.
