Description

<p>The S200 series MCB is a robust solution designed for both commercial and industrial applications, offering reliability and efficiency in electrical circuit protection. With a rated current of 20 A, this miniature circuit breaker (MCB) ensures optimal performance within its operational parameters.</p><p>Engineered to withstand high impulse voltages, the MCB features a rated impulse withstand voltage of 4 kV. It operates efficiently with a rated insulation voltage of 440 V and accommodates systems with a rated voltage of 400/415 VAC. The power loss is minimal at just 2.5 W, contributing to energy efficiency in larger systems.</p><p>This device boasts a three-pole configuration, providing comprehensive protection across all connected phases. Its breaking capacity stands at an impressive 10 kA at 400 VAC, ensuring reliable interruption capability during overloads or short circuits.</p><p>In terms of protection against external factors, the MCB offers an IP20 degree of protection, suitable for environments where basic ingress protection from solid objects is sufficient. The screw clamp terminal type facilitates secure connections with a tightening torque specification of 2.8 N-m.</p><p>The compact design measures 52.5 mm in width, 88 mm in height, and has a depth of 69 mm—ideal for installations where space is limited yet performance cannot be compromised.</p><p>Conforming to rigorous standards such as AS/NZS 60898-1 and AS/NZS 60947-2 as well as UL1077 approvals assures compliance with international safety norms and enhances user confidence in diverse settings.</p><p>Operating effectively within standard frequency ranges (50/60 Hz), it also exhibits remarkable electrical durability with up to 20,000 cycles—a testament to its longevity under regular use conditions. Additionally, it supports short-circuit capacities up to 6 kA which aligns well with typical industrial requirements.</p><p>For ease of installation on DIN rails common in industry-standard setups, the product includes practical features like wire stripping length guidance set at precisely12.5 mm while accommodating cable cross sections up top/bottom sides measuring35 sq-mm respectively—offering flexibility during wiring tasks without compromising security or functionality over time due largely due part by maintaining consistent bulbar cross section measurements(10sq-mm).</p><p>Designed specifically considering environmental variations: operational ambient temperature range extends from -25&amp;#176;C through +55&amp;#176;C whereas storage conditions allow broader margins between -40&amp;#176;C until reaching70&amp;#176;C maximum limits safely housed inside RAL7035 grey-coloured casing blending seamlessly into most equipment rooms aesthetically pleasing manner too!</p><p>Finally featuring C curve type characteristic provides balanced tripping response times suitable wide array load types encountered daily basis making this versatile choice professionals seeking dependable protective devices meet their needs head-on confidently every step way!</p>
