The S800S series MCB (Miniature Circuit Breaker) is a robust and reliable solution for commercial and industrial applications, designed to ensure electrical safety and efficiency. This three-pole circuit breaker is engineered with precision to meet the demanding requirements of modern electrical installations.
With a rated current of 40 A, the S800S MCB provides dependable protection against overloads and short circuits. It operates effectively within a voltage range of 400/690 VAC, making it suitable for diverse electrical environments. The device also boasts an impressive breaking capacity of 50 kA at 400 VAC, ensuring that it can handle high fault levels without compromise.
Safety is paramount in any electrical system, and this MCB does not disappoint. It features a degree of protection rated at IP20, safeguarding internal components from dust ingress while maintaining optimal performance. The unit's housing color is RAL 7035 Grey, providing a professional appearance that blends seamlessly into various settings.
The S800S series adheres to international standards such as IEC/EN 60947-2, IEC/EN 60898-1, and UL 1077. These certifications underscore its quality and reliability in delivering consistent performance over time. With an electrical durability rating of up to 6000 cycles, users can trust in its long-term operational capabilities.
Designed for ease of installation, the MCB features screw clamp terminals with a tightening torque specification of 3.5 N-m. Its compact dimensions—81 mm width by 95 mm height by 82.5 mm depth—facilitate straightforward integration into existing panels or new projects via DIN rail mounting.
The release type C curve ensures balanced protection between overload conditions and short-circuit scenarios while maintaining system stability during normal operations. Additionally, the unit supports cable cross sections up to 50 sq-mm on both top and bottom connections.
Engineered for resilience across varying environmental conditions, the S800S operates efficiently within temperatures ranging from -25°C upwards—a testament to its versatility in different climates or application areas.
In terms of impulse withstand capability, it stands strong at an impressive rating of 8 kV coupled with an insulation voltage capacity reaching up towards higher thresholds like those found around
