<p>For professionals in the electrical engineering and automation sectors, selecting components that meet specific technical requirements is crucial. The MPS3 series key-operated switch offers a robust solution for those seeking reliability and compliance with industry standards.</p><p>Crafted from durable plastic, this non-illuminated switch presents an understated black finish, making it suitable for various industrial settings. This device operates efficiently within a temperature range of -25 to 70 degrees Celsius, ensuring consistent performance even in demanding environments.</p><p>The MPS3 series switch adheres to multiple international standards and approvals, including CSA C22.2 No. 14, DIN 40050-9, EN 50013, IEC/EN 60073, IEC/EN 60529, IEC/EN 60947-1, IEC/EN 60947-5-1, IEC/EN 60947-5-5, and UL 508. These certifications affirm its quality and suitability for global applications.</p><p>Technically speaking, this switch boasts a rated insulation voltage of up to 690 volts and can withstand impulse voltages of up to 6 kV. Its contact configuration features two normally closed (2NC) contacts which are ideal for safety-related applications requiring reliable disconnection when activated.</p><p>The actuator type is key-operated with a maintained function across positions A, B, and C. This feature ensures that once engaged or disengaged by the operator using the key mechanism; the switch remains in that position until manually reset—ideal for scenarios where stability is paramount.</p><p>With a rated thermal current capacity of up to 10 amperes (A), this device supports substantial electrical loads without compromising safety or functionality. The cutout size measures at a standard diameter of 22 mm allowing easy integration into existing panels or systems designed around similar dimensions.</p><p>In summary,the MPS3 series key-operated switch combines practicality with high-level compliance making it an excellent choice for engineers who prioritize both operational efficiency and adherence to stringent industry standards while working on projects within Australia or internationally compliant markets</p>
