Description

The S800HV Series MCB is a robust and reliable miniature circuit breaker designed for commercial and industrial applications. With a rated current of 8 A, this device offers optimal protection for electrical circuits by preventing overloads and short circuits. Its impressive rated impulse withstand voltage of 8 kV ensures resilience against transient overvoltages, making it suitable for environments prone to electrical surges. This MCB operates effectively within a wide range of voltages, supporting both 580 VAC and 1000 VAC systems. The rated insulation voltage stands at an impressive 1000 V, providing excellent safety margins in high-voltage scenarios. Featuring a breaking capacity of 4 kA at 1000 VAC, the S800HV ensures that any fault conditions are swiftly managed to minimize downtime and equipment damage. Designed with practicality in mind, the S800HV Series features three poles and adheres to release type K characteristics. It has been tested under rigorous standards such as IEC/EN 60947-2 and UL 1077, guaranteeing compliance with international safety norms. The product's degree of protection is IP20, offering basic protection against solid objects larger than 12 mm while ensuring user safety during operation. Installation is straightforward thanks to its DIN rail mounting capability. The device measures a compact width of 81 mm, height of 142 mm, and depth of 82.5 mm—ideal dimensions for space-constrained panels or enclosures. To ensure secure connections, it supports cable cross-sections up to 50 sq-mm on both top and bottom terminals with a tightening torque requirement of just 3.5 N-m. For enhanced operational performance across varying conditions, the S800HV operates efficiently at temperatures ranging from -25°C upwards—a testament to its durability in diverse climates typical in Australia’s industrial landscape. With an overvoltage category rating of III and curve type K response characteristic tailored for specific application needs like motor loads or transformers—the S800HV provides tailored solutions without compromising on reliability or safety. The housing comes in RAL 7035 grey—a neutral color that seamlessly integrates into most switchgear designs while maintaining aesthetic consistency across installations. Overall, the S800HV Series MCB is engineered not only to meet but exceed expectations where dependable circuit protection is paramount; it's an essential component for those seeking peace-of-mind through proven technology backed by stringent standards adherence.
