Wyłącznik serii 187 - montaż powierzchniowy 100 A

The BLUE SEA 187 series circuit breaker is an electrical protection device designed for marine systems. It protects circuits against overcurrents and short circuits, ensuring the safety of connected equipment and the boat's electrical system. It is specifically designed for surface mounting.

This BLUE SEA 187 series circuit breaker has a rated current of 100 Amperes (A). This means it is designed to operate normally with currents up to 100A and will trip if this value is exceeded to protect the circuit.

This circuit breaker is designed to operate with direct current (DC) electrical systems ranging from 12V DC to 48V DC. It is therefore compatible with most standard marine electrical installations.

The "ignition protected" marking means this circuit breaker is designed not to generate sparks during normal operation or tripping. This feature makes it safe for installation in areas potentially exposed to fuel vapors, such as engine compartments, thereby reducing the risk of explosion or fire.

This circuit breaker has a manual reset function. After tripping due to an overcurrent or short circuit, it must be manually reset to restore power to the circuit.

This circuit breaker is ideal for protecting marine equipment with high current consumption. Typical applications include protection for:

WindlassesBow thrustersInvertersBattery chargersOther equipment requiring robust protection against overcurrent.

The 187 series circuit breaker stands out with its surface-mount design, robustness, and ignition protection ("ignition protected"), making it suitable for demanding environments. In comparison:

The CLB series offers push-button circuit breakers for less demanding applications.The C series provides panel-mount options, often for electrical panels.The 187 is the preferred choice for installations requiring enhanced safety in potentially hazardous areas.

For surface mounting, the circuit breaker is typically secured using screws through the mounting holes on its housing. It is important to choose a flat and solid surface. Ensure the location is easily accessible for manual reset and is protected from direct water spray if it is not an "ignition protected" area.

No, this BLUE SEA 187 series circuit breaker is specifically designed for direct current (DC) systems, with a voltage range from 12V DC to 48V DC. It must not be used to protect alternating current (AC) circuits.

Yes, this circuit breaker is designed to replace a 100A fuse in a DC circuit. The main advantage is its manual reset capability after tripping, eliminating the need to physically replace a blown fuse, which is more convenient at sea.

After a trip, the circuit breaker lever will generally be in the middle or in the "OFF" position. To reset it, you must first push the lever fully to the "OFF" position (if it is not already there), then move it back to the "ON" position. Before resetting, it is advisable to identify and correct the cause of the trip (overload or short circuit).

Yes, the BLUE SEA 187 series circuit breaker is designed with corrosion-resistant materials, such as its thermosetting plastic housing and tinned copper terminals. These features provide good durability in a salty marine environment.

Yes, thanks to its "ignition protected" certification (protected against ignition) in accordance with SAE J1171, this circuit breaker is specifically designed and approved for safe installation in engine compartments or other areas where fuel vapors may be present.
