PLASTIMO Bulkhead Circuit Breaker | 185-Series

Category: Electronics
Subcategory: Electrical connections

Ensure the ultimate safety and reliability of your vessel´s high-current electrical systems with the PLASTIMO 185-Series Bulkhead Circuit Breaker. Engineered for the demanding marine environment, this compact and robust circuit breaker is the essential protective device for your most critical onboard equipment. It provides superior protection against overcurrent and short-circuit conditions, safeguarding expensive components like windlasses, bow thrusters, and other powerful electric motors from potentially catastrophic damage. By choosing Plastimo, you´re investing in peace of mind and uncompromising electrical safety on the water.

This unipolar thermal circuit breaker is specifically designed to handle the heavy loads associated with modern boating. Its primary function is to automatically interrupt the flow of electricity when it exceeds a safe level, preventing overheating, wire damage, and the risk of fire. Its robust construction and reliable thermal trip mechanism make it a far superior alternative to standard fuses for high-amperage applications.

Key Benefits:

* Unmatched Safety in Hazardous Areas: A standout feature is its explosion-proof design, fully compliant with the rigorous SAE J1171 standard for ignition protection. This means the circuit breaker is sealed to prevent any internal sparks from igniting external flammable vapors, making it safe for installation in engine compartments and other areas where fuel fumes may be present.
* Superior High-Current Protection: With an impressive interrupt capacity of 3000A DC, this breaker is built to safely handle the massive fault currents that can be generated by heavy-duty DC systems. This ensures that even in a severe short-circuit event, the device will operate effectively to protect the circuit.
* Reliable Overload Defense: The thermal trip mechanism is designed to respond to sustained overloads, typical when a motor is strained or stalled. This protects the motor´s windings and associated cabling from the slow-burn damage that can lead to premature failure.
* Controlled Power Restoration: Featuring a manual reset lever, the breaker gives you full control. After a trip, it cannot be held closed in an overload condition ("trip-free" design). This forces an operator to acknowledge the fault and investigate the cause before safely restoring power with a simple flip of the switch.
* Durable and Compact Design: The bulkhead-mount design allows for a secure, space-saving installation on any flat vertical surface. Its compact dimensions ensure it can fit into tight electrical lockers or panels, while the 6.35 mm stud terminals provide a solid, low-resistance connection for your electrical cables.
