Off-Grid Inverter Circuits Placement between off-grid inverter DC inputs and batteries for safety and isolation. DC Power Distribution Protecting main or auxiliary DC power distribution and charging circuits. Automotive & Marine Suitable for various DC applications in vehicles, boats, and RVs requiring ignition protection. Common Questions What is a thermal overcurrent protection device? A thermal overcurrent protection device, like this circuit breaker, uses a bimetallic strip or similar element that heats up and bends when exposed to sustained excessive current. This bending action triggers a mechanism to open the circuit, cutting off power and preventing damage from overloads. Can this circuit breaker be used as a main On/Off switch? Yes, this circuit breaker features a manual-break option, allowing it to function as an On/Off switch. This provides a convenient way to disconnect or reconnect your DC system for maintenance or when not in use. What does the IP67 rating mean for this product? An IP67 rating signifies that the circuit breaker is fully protected against dust ingress and can withstand temporary immersion in water up to 1 metre for 30 minutes. This makes it suitable for outdoor and marine environments where exposure to moisture and dust is common. Is this circuit breaker suitable for high-temperature environments? Yes, the circuit breaker is constructed from UL94V-0 rated thermal plastic, designed to withstand high temperatures. Its operating temperature range is -32°C to 82°C, making it suitable for various demanding conditions. Installation Notes This circuit breaker is designed for surface mounting. Ensure correct polarity when connecting to your DC system. Use appropriate M6 terminals and ensure secure, tight connections to prevent overheating. Always consult a qualified electrician or refer to local electrical codes for installation. Mount in a location that allows for adequate air circulation, even with its robust temperature ratings. Before You Buy Verify the 60A rating is suitable for your specific DC circuit's maximum current draw. Confirm your system voltage (12V, 24V, or 48V DC) is compatible. Consider the physical dimensions (74 x 48 x 37 mm) for your intended mounting location. Ensure you have the necessary M6 terminal connectors for installation. Review the application suitability for solar, marine, automotive, or general DC distribution. Always verify product specifications and compatibility with your specific system requirements before purchase. All information is based on verified manufacturer data and industry standards.
