Built-In Protection Functions This 200A DC circuit breaker is engineered with multiple safety features to ensure reliable operation and system protection. It offers thermal overcurrent protection, automatically tripping to prevent damage from excessive current. The unit is constructed from UL94V-0 rated thermal plastic, providing high flame retardance and self-extinguishing properties. • With an IP67 enclosure rating, it is fully protected against dust ingress and can withstand temporary immersion in water, making it suitable for demanding environments. • Furthermore, it is ignition-protected, meeting international standards S.A.E. J1625, J1171, and UL1500, which certifies its safe use in marine engine compartments and other areas where flammable vapours may be present. Common Questions What is the main advantage of a resettable circuit breaker over a fuse? A resettable circuit breaker, like this 200A model, automatically or manually resets after an over-current event, allowing the system to be re-energised without needing to replace a blown fuse. This saves time and the cost of replacement fuses. Can this circuit breaker be used in marine environments? Yes, this circuit breaker is specifically designed for marine applications. It is IP67 rated for water and dust resistance and meets international ignition protection standards (S.A.E. J1171, UL1500), making it safe for use in engine compartments where flammable vapours may be present. What does the UL94V-0 rating signify? The UL94V-0 rating indicates that the thermal plastic material used in the circuit breaker's construction has a high level of flame retardance. It means that burning stops within 10 seconds on a vertical specimen, with no flaming drips, contributing to enhanced safety. Is this circuit breaker suitable for off-grid solar battery systems? Absolutely. This 200A DC circuit breaker is ideal for protecting connections between solar charge controllers and batteries, or between off-grid inverter DC inputs and battery banks, ensuring reliable over-current protection for your solar setup. Installation Notes Intended for surface mounting. Ensure a flat, stable surface for secure installation. Always consult a qualified electrician or installer for correct wiring and system integration. Ensure all connections are tight and secure to prevent arcing and ensure optimal performance. Observe correct polarity when connecting to DC systems. Before You Buy Verify the 200A rating is appropriate for your specific DC system's current requirements. Confirm compatibility with your system's voltage (12V, 24V, or 48V DC). Consider the physical dimensions (86 x 48 x 37 mm) and M10 terminal size for your installation space and cabling. Review any specific time-current and temperature derating graphs from the manufacturer to ensure optimal selection for your application. Please verify all specifications and compatibility requirements with your system before purchase. Product details are based on manufacturer specifications and verified standards.
