<p>The S800HV series MCB is a robust solution designed for commercial and industrial applications, offering reliable protection with its comprehensive features. This miniature circuit breaker (MCB) is engineered to handle demanding electrical environments, ensuring safety and efficiency in power distribution systems.</p><p>With a rated current of 40 A, the S800HV MCB provides dependable performance under various load conditions. It operates effectively within a voltage range of 580 VAC to 1000 VAC, making it versatile for different electrical setups. The product also boasts an impressive rated impulse withstand voltage of 8 kV and an insulation voltage of 1000 V, underscoring its capability to endure high-voltage transients and maintain operational integrity.</p><p>The breaking capacity stands at 4 kA at 1000 VAC, ensuring that the MCB can interrupt fault currents efficiently without compromising on safety. Additionally, the device has been tested to meet standards such as AS/NZS 60947-2 and UL 1077, providing assurance of its quality and reliability in adherence to international benchmarks.</p><p>Designed with practicality in mind, the S800HV features a single pole configuration with dimensions measuring 27 mm in width, complemented by a height of 142 mm and depth of 82.5 mm. This compact design facilitates easy integration into existing electrical panels while maintaining space efficiency.</p><p>Installation is straightforward thanks to its DIN rail mounting type and screw clamp terminal connections which support cable cross sections up to 50 sq-mm both top and bottom. The tightening torque requirement is set at a precise 3.5 N-m ensuring secure connections that minimize maintenance needs over time.</p><p>For environmental resilience, this MCB operates within temperatures ranging from -25&#176;C upwards making it suitable for diverse climates across Australia. Its housing comes in RAL 7035 grey color providing not just aesthetic appeal but also durability against wear and tear.</p><p>Moreover, the degree of protection rated at IP20 ensures basic protection against solid objects greater than or equal to &#216;12mm like fingers or similar sized objects; meanwhile it maintains an IP2 degree of pollution level indicating suitability for environments where only non-conductive pollution occurs except occasionally temporary conductivity caused by condensation may be expected.</p><p>The release type K curve characteristic allows this breaker model optimal responsiveness during overload conditions typical within industrial settings thereby reducing downtime risks associated with equipment failures due overloads or short circuits – all contributing towards enhanced operational continuity wherever applied.</p>
