Description

<p>This Miniature Circuit Breaker (MCB) is a robust and reliable choice for industrial and commercial applications, designed to protect electrical circuits from overloads and short circuits. With a rated current of 25 A, it ensures efficient performance in various settings. The MCB&amp;#39;s rated impulse withstand voltage of 6 kV and insulation voltage of 500 V provide excellent protection against electrical surges.</p><p>Operating at a rated voltage of 240 VAC, this device offers a power loss of only 3.2 W, making it energy-efficient. It features a single pole with a high breaking capacity of 15 kA, ensuring safety during fault conditions. The degree of protection ranges from IP20 to IP40, allowing for versatile application environments.</p><p>Installation is straightforward with the screw clamp terminal type that requires a tightening torque of 2.8 N-m. Its compact dimensions—17.5 mm in width, 88 mm in height, and 67.6 mm in depth—make it suitable for space-constrained installations on DIN rails.</p><p>Compliant with standards such as CSA 22.2 No. 235, IEC/EN 60947-2, and UL 1077, this MCB meets stringent international safety requirements. Weighing just 0.124 kg, it&amp;#39;s easy to handle during installation or maintenance.</p><p>The S300P series MCB operates efficiently across frequencies ranging from 50 to 60 Hz and boasts an impressive electrical durability with up to 20,000 cycles. Designed for environments with pollution degree IP3, it maintains functionality even under challenging conditions.</p><p>Its K curve type allows for precise tripping characteristics suited for specific load types commonly found in industrial settings while the wire stripping length requirement is set at an optimal length of 14 mm.</p><p>Capable of operating within an ambient temperature range from -40&amp;#176;C to +70&amp;#176;C ensures reliability across diverse climates typical in Australia’s varied geography while its dielectric test voltage stands strong at up to two kilovolts providing added assurance against insulation breakdowns</p><p>The flexible mounting position means you can install this breaker anywhere along your circuit layout without being restricted by orientation constraints; similarly arbitrary power supply connection further adds flexibility during setup processes</p><p>Finished off elegantly using RAL7039 grey housing colour scheme blends seamlessly into most standard panel designs enhancing aesthetic appeal whilst retaining full functional integrity Manufacturer Part Number: S300P</p>
