Description

<p>The SH200 series MCB is a robust and reliable solution for industrial and commercial electrical distribution requirements. Designed to meet the rigorous standards of AS/NZS 60898-1 and IEC/EN 60898-1, this miniature circuit breaker ensures safety and efficiency in various applications.</p><p>With a rated current of 50 A, the SH200 MCB is suitable for handling substantial electrical loads. It operates effectively within a rated voltage range of 400/415 VAC, making it versatile for different power systems. The device&amp;#39;s breaking capacity stands at an impressive 6 kA, providing adequate protection against short circuits.</p><p>The MCB features a rated impulse withstand voltage of 4 kV and a rated insulation voltage of 440 V, offering enhanced durability against transient overvoltages. Its electrical durability spans up to 10,000 cycles, ensuring long-lasting performance in demanding environments.</p><p>Designed with practicality in mind, the SH200 comes with a screw clamp terminal type that supports cable cross sections up to 25 sq-mm on both top and bottom connections. The tightening torque requirement is set at 2 N-m for secure installations.</p><p>In terms of dimensions, the unit measures 52.5 mm in width, 85 mm in height, and has a depth of 69 mm which facilitates easy integration into existing setups. The pole width is standardized at 17.5 mm per pole across its three poles configuration.</p><p>For installation flexibility, this MCB can be mounted on standard DIN rails—a common requirement in modern electrical panels—and operates efficiently within ambient temperatures ranging from -25 to +55 degrees Celsius while being able to be stored safely between -40 to +70 degrees Celsius.</p><p>The degree of protection offered by this model is IP20 which provides basic protection against solid objects like fingers or small tools but isn&amp;#39;t suited for moisture exposure—typical for indoor use where additional enclosure might be necessary if higher ingress protection levels are required.</p><p>Its actuator type uses an intuitive toggle mechanism that simplifies operation under varied conditions while maintaining reliability throughout its lifespan. Additionally,the housing color RAL7035 grey provides an unobtrusive aesthetic that blends well with most industrial settings without drawing unnecessary attention yet remains easily identifiable among other components within switchboards or control cabinets thanks also partly due its collection branding as part Series SH200 known widely recognized across industry sectors globally trusted choice professionals alike seeking dependable cost-effective protective solutions their electrical infrastructure needs</p>
