Thermal Circuit Breaker with LED – 60A to 300A | Panel Mount

Dependable DC Protection in 12V / 24V / 48V systems

This flush-mount thermal breaker with a built-in LED signal ensures reliable protection of your DC power networks against short circuits and overload. Equipped with a manual reset and IP66 waterproofing, it is designed for integration directly into boat panels, offering safe and durable protection of your onboard equipment.

Operation and Key Features

Automatic Trip Mechanism

During an overload event, the breaker automatically interrupts the circuit. The integrated LED then switches on, clearly showing that protection has been triggered. Restoring power is achieved manually via the reset button on the breaker face.

LED Feedback System (ON/OFF)

• LED off: normal circuit activity
• LED on: breaker open, fault detected
• Manual Reset button: restores supply manually

Durable Construction for Harsh Environments

• M6 or M10 stainless studs depending on current rating
• IP66 panel sealing: resistant to spray and saltwater
• Temperature range: −32°C to +82°C
• Ignition Protected ISO 8846: suitable for fuel compartments

Application Examples by Amperage

Integration and Installation

Typical setups

• RIBs and cruisers: helm panels, bilge compartments
• Large vessels: machinery protection, bridge control panels
• RVs & 4x4s: auxiliary high-current modules
• Solar storage: between battery packs and inverters
• Industrial machinery: hydraulic or electric drive systems

Comparison with other devices

Breaker vs. battery isolator – The isolator needs user intervention, while the breaker trips automatically and provides instant LED status.

Breaker vs. differential switch – The differential protects people in 230V AC; this unit protects equipment in 12/24/48V DC.

Breaker vs. fuse – Unlike a disposable fuse, the breaker is resettable and avoids replacing components at sea.
