Marine Thermal Circuit Breaker with LED Indicator – 60A to 300A

Reliable protection in DC 12V / 24V / 48V

This single-pole thermal circuit breaker with an LED indicator effectively protects your DC electrical circuits against overcurrent and short circuits. With a manual reset and IP66 sealing, it is purpose-built to secure your marine electrical installation and safeguard your electrical equipment from failures.

Operation and benefits

Automatic protection principle

When an overcurrent is detected, the automatic trip instantly cuts power. The integrated LED on the button then lights up, clearly indicating the open state. Reset is performed manually via the accessible reset button.

LED visual indicator (ON/OFF)

LED off: circuit active, normal operation
LED on: breaker tripped, circuit open
Reset button: manual circuit restoration

Reinforced marine construction

Stainless-steel studs M6 or M10 depending on amperage
IP66 sealing: protection against fresh and salt water
Operating temperature: −32°C to +82°C
Ignition Protect ISO 8846: suitable for gasoline engine compartments

Recommended onboard applications by amperage

Amperage	Voltage	Main applications	Model
60A	12V/24V	600W inverters, upstream protection for switch panels, residential solar systems, 12V cooktops, high-power LED lighting	CBL60
120A	12V/24V	12V windlass, medium bilge pumps, 1500W inverters, RV auxiliary systems, medium electrical appliances	CBL120
200A	12V/24V	24V electric winch, industrial bilge pumps, solar arrays with high-power inverter, heavy-duty electrical equipment	CBL200
250A	12V/24V	24V bow thruster, hydraulic swim platform, industrial winching systems	CBL250
300A	12V/24V/48V	48V bow thruster, 48V solar battery-inverter systems, naval hydraulic equipment	CBL300

Installation versatility

Usage environments

Pleasure boats: bilge, engine compartment, switch panel
Professional vessels: marine industrial installations
RVs and 4×4 vehicles: high-current auxiliary circuits
Solar installations: protection between batteries and inverters
Mobile equipment: platforms, construction machinery

Comparison with other protections

Thermal breaker vs. battery switch – A battery switch requires preventive manual action, whereas a thermal breaker trips automatically during overcurrent and provides LED visual diagnostics.

Thermal breaker vs. RCD – An RCD protects people against leakage currents in single-phase 230V AC systems, while this single-pole thermal breaker protects equipment against overloads in 12/24/48V DC.

Thermal breaker vs. contactor – A contactor remotely opens/closes a circuit; a thermal breaker automatically protects against overcurrent with local manual reset.

Thermal breaker vs. fuse – Unlike a fuse that melts, the breaker is manually reset with no part replacement. Cost-effective and practical at sea.

Why choose this thermal breaker

Enhanced safety

Automatic overload protection with immediate visual feedback. Ideal for unattended or hard-to-reach areas such as bilge compartments.

Marine-grade reliability

IP66 waterproof build with corrosion-resistant stainless studs. Designed for the harshest marine environments.

Ease of use

Simple push-button reset, LED diagnostics, quick drop-in to existing circuits.

Operating economy

No consumable parts unlike fuses. Quick intervention after a trip.

FAQ

Frequently Asked Question

What's the difference between a Thermal Breaker and a Differential Breaker?

Thermal Breaker: This device protects your electrical equipment from damage caused by overloads and short circuits. It operates by sensing excessive heat generated by high current flow and automatically trips to open the circuit.
Differential Breaker (RCD): An RCD is a critical safety device that protects people from electric shock and prevents fires caused by current leakage. It works by detecting an imbalance in current and is typically used in AC (alternating current) systems.

How do I choose the correct size for my thermal breaker?

To choose the correct thermal breaker size, you need to determine the maximum continuous amperage of the electrical device you want to protect. The breaker's amperage rating should be slightly higher than the device's normal operating current to prevent nuisance tripping, but low enough to protect the circuit from damage.

Key Principle: The thermal breaker should be sized to protect the weakest link in the circuit, which is usually the smallest gauge wire.

Recommendation: A good rule of thumb is to choose a breaker that is about 15-20% larger than the expected continuous current draw of the device.

How to Test a Thermal Breaker?

To check if your thermal breaker is working correctly, you can use the built-in features of your model.

Check the LED: Your thermal breaker is equipped with an integrated LED. When the breaker is triggered due to an overload or short circuit, the LED will light up, visually confirming that the circuit is open. If the breaker trips and the LED does not light up, this indicates a power issue on the input side of the breaker.
Verify Power Supply: If the LED does not light up after a trip, check your battery switch to ensure it is on and verify that the battery is properly connected to the breaker's input. The breaker requires power to illuminate the LED, so an unlit LED can be a simple diagnostic for power loss.

How to Install Thermal Breaker?

A thermal breaker should always be installed on the positive (+) signal of the circuit you want to protect. The most effective placement is as close as possible to the power source (e.g., the battery) to safeguard the entire length of the cable running to the device.

For example:

For an Inverter: Place the breaker on the positive cable directly before the inverter's input terminal.
For a Windlass: If the cable runs across the boat, install the breaker close to the battery to protect the entire cable run from any potential fault.

Why is the "Ignition Protected" feature important for a boat?

The Ignition Protect ISO 8846 certification is a crucial safety standard for any electrical component installed in an enclosed space where gasoline vapors might be present, such as an engine compartment. This certification guarantees that the product will not generate a spark or heat that could ignite flammable gases, thus significantly reducing the risk of fire or explosion on board.
