Description

<p>The SH200 series MCB is a robust and reliable choice for industrial and commercial electrical installations. Designed to meet the rigorous demands of modern applications, this miniature circuit breaker (MCB) offers a blend of performance and safety features that cater to your technical needs.</p><p>With a rated current of 20 A, the SH200 ensures efficient operation within its specified limits. It supports a rated voltage range of 400/415 VAC, making it versatile for various electrical systems. The device&amp;#39;s breaking capacity stands at 6 kA, providing dependable protection against short circuits.</p><p>Safety is paramount in any electrical setup, and the SH200 does not disappoint with its IP20 degree of protection. This ensures that the unit is safeguarded against solid objects larger than 12 mm in diameter. Additionally, its compliance with AS/NZS 60898-1 and IEC/EN 60898-1 standards underscores its reliability and adherence to industry norms.</p><p>The MCB&amp;#39;s design incorporates a screw clamp terminal type capable of handling cable cross sections up to 25 sq-mm on both top and bottom connections. This feature facilitates secure wiring connections while supporting ease of installation with DIN rail mounting compatibility.</p><p>In terms of durability, the SH200 boasts an impressive electrical endurance of up to 20,000 cycles. This longevity is complemented by an ambient operating temperature range from -25&amp;#176;C to +55&amp;#176;C, ensuring consistent performance even under varying environmental conditions. For storage purposes, it can withstand temperatures as low as -40&amp;#176;C up to +70&amp;#176;C.</p><p>The toggle actuator type allows for straightforward operation while maintaining user-friendly interaction with the device. Moreover, it features a C curve type characteristic which provides optimal tripping behavior suitable for general-purpose applications where medium inrush currents are expected.</p><p>Physically compact yet sturdy in construction; measuring at a width of 52.5 mm height at 85 mm depth extending outwards by only about another quarter inch or so further back into your panel space thanks largely due part because each pole spans just mere centimeters across—approximately around seventeen-and-a-half millimeters wide per unit! The housing sports RAL7035 grey color adding aesthetic consistency alongside other equipment inside enclosures too!</p><p>Overall when considering power loss sits merely around two-point-five watts plus impulse voltage rating hits four kilovolts respectively; all these factors combined make choosing this particular model within collection line-up quite logical rational decision indeed given specific technical requirements may have outlined beforehand during planning phases earlier stage project development lifecycle itself!</p>
