<p>In the realm of industrial and commercial electrical systems, choosing the right manual switch is crucial for ensuring operational efficiency and safety. This product offers a robust solution with its comprehensive design tailored for distribution board installations.</p><p>With a rated current of 250 A, this manual switch caters to substantial power requirements, making it ideal for various industrial applications. It operates effectively at a rated voltage of 415 VAC, further supported by its impressive rated insulation voltage of 1000 V. The switch&#39;s ability to handle high electrical demands is complemented by its rated impulse withstand voltage of 12 kV and a short-time withstand current rating of 8 kA.</p><p>The physical dimensions are compact yet sturdy, measuring 205 mm in width, 150 mm in height, and 160 mm in depth. Despite its solid build weighing in at 4.1 kg, it maintains an IP20 degree of protection against ingress from fingers or similar objects greater than 12mm.</p><p>This device adheres to rigorous standards including RoHS, REACH, and CE approvals—ensuring compliance with essential safety regulations while minimizing environmental impact. Its NEMA rating as NEMA 1 signifies suitability for indoor use where minimal exposure to dust or moisture is expected.</p><p>Designed with user convenience in mind, this manual switch features an ergonomic pistol-type handle for ease of operation. The front mode operation allows straightforward access while the screw clamp terminal type ensures secure connections. The unit includes both handle and shaft components necessary for installation.</p><p>For enhanced functionality and safety during maintenance or emergency situations, the switch is interlockable and padlockable in the O-position—providing peace of mind that unauthorized adjustments can be prevented when needed.</p><p>The transition type is open with line terminals positioned either top-in bottom-out or bottom-in top-out depending on installation preferences—adding flexibility to suit various system configurations. Additionally, indicators marked I-O-II offer clear visual cues regarding operational status.</p><p>An air thermal current capacity matching its rated current at 250 A alongside a power loss figure of just 6.5 W highlights efficient performance without compromising on energy consumption levels—a critical consideration within energy-conscious environments today.</p><p>Mounting this device via four-hole front mounts ensures stability upon integration into existing setups; meanwhile tightening torque specifications reach up to22 N-m guaranteeing reliable fixture throughout usage cycles over time thereby reducing potential downtime risks associated otherwise under less stringent conditions elsewhere across industry settings globally alike!</p>
