<p>When selecting a Miniature Circuit Breaker (MCB) for your commercial or industrial needs, the S800N series offers a robust solution that aligns with stringent safety and performance standards. This MCB is designed to handle demanding applications with precision and reliability.</p><p>The device operates at a rated current of 25 A and supports both 400 VAC and 690 VAC, making it versatile for various electrical systems. Its rated insulation voltage of 690 V ensures enhanced protection against potential electrical hazards. With an impressive breaking capacity of 36 kA at 400 VAC, this MCB can effectively interrupt high fault currents, safeguarding your equipment from damage.</p><p>One of the standout features is its rated impulse withstand voltage of 8 kV, providing resilience against transient overvoltages typically caused by lightning strikes or switching surges. The degree of protection is IP20, suitable for indoor use where exposure to moisture or dust is minimal.</p><p>In terms of dimensions, the MCB measures 54 mm in width, 95 mm in height, and has a depth of 82.5 mm. It fits seamlessly onto standard DIN rails for easy installation in existing setups. The housing comes in RAL 7035 Grey, maintaining a professional aesthetic consistent with most industrial environments.</p><p>For those concerned about energy efficiency, the power loss is kept low at just 4.3 W under normal operating conditions. The S800N series also boasts an electrical durability rating capable of enduring up to 10,000 operational cycles.</p><p>The product adheres to international standards IEC/EN 60947-2 and IEC/EN 60898-1 ensuring compliance with global safety norms. Additionally, it supports cable cross-sections up to 50 sq-mm both on top and bottom connections allowing flexibility in wiring configurations.</p><p>With a tightening torque requirement set at 3.5 N-m this MCB provides secure connections preventing accidental loosening over time due to vibrations or thermal cycling common in industrial settings.</p><p>This model features a C curve type which means it&#39;s particularly suited for applications where moderate levels of inductive loads are present such as motors transformers or fluorescent lighting circuits offering balanced protection without unnecessary tripping during start-up surges.</p><p>Overall if you&#39;re looking for an efficient reliable circuit breaker that meets high-performance criteria while being straightforward to integrate into existing systems look no further than this member from the S800N collection perfect for commercial and industrial applications alike.</p>
