The 16A 2P DC Circuit Breaker 600V is specifically engineered for safeguarding solar DC strings in accordance with the UL489B standard. Its primary functions include overload protection, anti-reflux capabilities, and short-circuit protection for solar PV systems, UPS (Uninterruptible Power Supply), and BESS (Battery Energy Storage Systems). The breaker's innovative design not only ensures safety but also enhances durability, promising a prolonged and reliable working life.
Key Features:
- Non-polarity: This feature of the 16A 2P DC Circuit Breaker 600V eliminates the need to worry about the correct orientation during installation. Whether connecting the breaker to the power source or load, the absence of polarity concerns simplifies the setup process. This not only saves time but also reduces the likelihood of errors, ensuring a hassle-free installation experience.
- High Short-Circuit/Breaking Capacity: The circuit breaker boasts a high short-circuit or breaking capacity, meaning it can effectively interrupt high currents in the event of a short circuit. By swiftly cutting off the flow of electricity under such circumstances, this feature helps prevent damage to the connected equipment or system. This capability enhances overall safety in electrical installations, providing peace of mind to users.
- Overload, Short Circuit, Unfrequent Operation, and Anti-Reflux Protection: Offering comprehensive protection, this circuit breaker guards against a range of potential electrical issues. It provides protection against overload situations, where the current exceeds the rated capacity of the circuit. Additionally, it effectively handles short circuits, swiftly cutting off power to prevent damage. The breaker also caters to infrequent operations, ensuring reliable performance even during sporadic usage. Furthermore, its anti-reflux protection prevents reverse flow of current, enhancing the reliability and longevity of connected equipment or systems.
- Rated Voltage 600V DC: With a rated voltage of 600V DC, this circuit breaker is designed to handle high voltage levels commonly found in DC applications, such as solar PV systems. This high voltage rating ensures compatibility with demanding electrical setups, offering flexibility in system design and application.
- Body Lengthening, Increased Electrical Clearance, and Creepage Distance: The circuit breaker features design enhancements aimed at enhancing safety and performance. By lengthening the body of the breaker, it increases the distance between electrical components, reducing the risk of electrical arcing and enhancing insulation. Additionally, increased electrical clearance and creepage distance further improve safety, especially in high-voltage environments. These design features collectively contribute to a safer and more reliable electrical installation.
- Rated Current 50A: With a rated current of 50A, this circuit breaker is capable of handling moderate to high current demands in DC circuits. This ensures compatibility with a wide range of applications, providing versatility in electrical system design and installation.
- Compliance with UL489B: The circuit breaker complies with the UL489B standard, which sets stringent safety and performance requirements for circuit protection devices. By adhering to this standard, the breaker demonstrates its reliability and suitability for various applications while ensuring compliance with industry regulations and standards. This compliance provides users with confidence in the quality and performance of the circuit breaker, assuring them of its reliability and safety.
