Description

<p>For professionals in the electrical engineering and automation industries, selecting a reliable Miniature Circuit Breaker (MCB) is vital for ensuring safety and efficiency. This particular MCB offers robust features that make it suitable for industrial applications, providing peace of mind with its solid performance profile.</p><p>The MCB is rated at a current of 50 A, making it capable of handling substantial electrical loads. It operates efficiently within a voltage range of 400/415 VAC, which aligns well with many industrial power systems. The device&amp;#39;s breaking capacity stands at an impressive 15 kA at 400 VAC, indicating its ability to interrupt significant fault currents safely.</p><p>Designed with practicality in mind, this MCB features two poles and utilizes a screw clamp terminal type for secure connections. The tightening torque specification is set at 2.8 N-m, ensuring optimal contact pressure without over-tightening.</p><p>In terms of dimensions, the unit measures a compact width of 35 mm, height of 88 mm, and depth of 69 mm. This makes it adaptable to various installation environments where space might be limited but reliability cannot be compromised.</p><p>The product adheres to stringent standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077 approvals—testaments to its compliance with international safety and performance benchmarks.</p><p>Operating across frequencies from 50 to 60 Hz provides flexibility in application scenarios around the globe. Additionally, the impulse voltage rating is set at an adequate level of 4 kV.</p><p>This MCB also boasts a short circuit capacity rated at up to 10 kA—a critical feature for protecting circuits from unexpected surges or faults that could otherwise cause damage or downtime.</p><p>With an IP20 degree of protection and housed in RAL 7035 grey casing typical for industrial environments, this breaker ensures durability against dust ingress while maintaining user safety during operation or maintenance activities.</p><p>Temperature resilience is another strong suit; it functions effectively between -25&amp;#176;C and +55&amp;#176;C during operation and can withstand storage conditions ranging from -40&amp;#176;C to +70&amp;#176;C without degradation—ideal for varying Australian climates.</p><p>Its curve type K characteristic means it&amp;#39;s designed specifically to handle inductive loads often found in motor applications common within industrial settings.</p><p>Finally yet importantly comes the environmental consideration: classified under Degree of Pollution IP3 ensures suitability even when installed in less than pristine conditions typical across many work sites today.</p><p> </p><p>Particularly belonging to the S200MUC collection signifies both quality assurance backed by proven manufacturing processes along with compatibility across similar system setups already existing onsite if expanding current installations rather than replacing outright becomes necessary down future project timelines ahead</p>
