Description

The S800HV Series MCB is a robust solution designed for both commercial and industrial applications, offering reliable protection with its comprehensive specifications. This miniature circuit breaker (MCB) is engineered to handle demanding environments, making it a practical choice for professionals seeking dependable electrical protection. At the core of this MCB's performance is its impressive rated current of 25 A, ensuring efficient operation across various applications. It supports dual voltage ratings of 580 VAC and 1000 VAC, providing flexibility in diverse electrical setups. The rated impulse withstand voltage stands at 8 kV, which enhances its resilience against transient overvoltages. Safety and durability are further emphasized by the MCB's breaking capacity of 4 kA at 1000 VAC and a rated short circuit current of the same value. These features are crucial for maintaining operational integrity during fault conditions. Additionally, the device complies with IEC/EN 60947-2 and UL 1077 standards, assuring users of its adherence to international safety protocols. Installation is straightforward thanks to its DIN rail mounting type, while the unit's dimensions—81 mm width, 142 mm height, and an overall depth of 82.5 mm—ensure it fits neatly into existing setups without requiring significant adjustments. The pole width measures at a compact 27 mm per pole. The S800HV Series also prioritizes user safety with an IP20 degree of protection against solid objects larger than 12mm in diameter. Furthermore, an IP2 degree of pollution rating signifies that this product can operate effectively in environments with non-conductive pollution only. Operational reliability is supported by a power loss specification of just 12.9 W and a tightening torque requirement set at an optimal level of 3.5 N-m for secure connections. Its cable cross-section capability accommodates up to two cables each measuring up to 50 sq-mm on both top and bottom terminals. Designed to perform across standard conditions found in Australia’s varied climate zones, this MCB operates efficiently within temperatures ranging from -25 degrees Celsius upwards—a vital consideration for installations subject to extreme weather fluctuations. With an overvoltage category rating of III indicating suitability for equipment installation downstream from primary distribution systems such as distribution boards or branch circuits—this series offers peace-of-mind through enhanced surge protection capabilities inherent within its design parameters. Finally housed in RAL7035 grey casing—a colour choice reflecting industry norms—the S800HV Series blends seamlessly into professional settings where aesthetics meet functionality without compromise on quality or performance metrics demanded by discerning technical audiences today.
