Description

<p>This accessory is designed to meet the rigorous demands of industrial and commercial applications, offering a robust solution for those requiring reliability and versatility. Engineered with precision, it operates efficiently within a rated voltage of 690 VAC/VDC and accommodates both 50 Hz and 60 Hz frequency settings. Its compact dimensions—30 mm in width, 48 mm in height, and 36 mm in depth—ensure that it fits seamlessly into various setups without occupying excessive space.</p><p>The accessory&amp;#39;s non-illuminated design enhances its durability, making it an ideal choice for environments where illumination is unnecessary or could be compromised by external factors. It features a screw terminal type with a tightening torque of 1 N-m, ensuring secure connections that withstand operational stresses. The connection type further supports this robustness with its screw configuration.</p><p>In terms of protection, the product boasts an IP20 rating, signifying effective protection against solid objects over 12 mm but not against water ingress. This makes it suitable for indoor use where moisture exposure is minimal. The device can operate comfortably within ambient temperatures ranging from -25 to 70 degrees Celsius and can be stored at temperatures between -40 to 85 degrees Celsius.</p><p>Designed specifically for use with pilot devices, this accessory includes a contact configuration of one normally closed (1NC) contact. It has been tested to endure impulse voltages up to 6 kV while maintaining an insulation voltage rating of up to 690 V. Its operational current ratings are flexible across different configurations: 0.55 A, 5 A, and up to a maximum of 6 A.</p><p>The mounting type is front-facing for easy installation or replacement in panels or control systems. In terms of connecting capacity, it&amp;#39;s adaptable; supporting flexible wires with ferrules ranging from single/double strands at sizes between 0.75 sq-mm to 2.5 sq-mm as well as solid wires within the same range.</p><p>Power loss is minimized at just 2.5 W which contributes positively towards energy efficiency goals especially critical in large-scale operations where every watt saved counts towards overall sustainability targets.</p><p>For ease during installation or maintenance tasks like wire stripping before connection setup—the recommended wire stripping length stands at precisely eight millimeters ensuring optimal fitment without excess material exposure which could lead potentially hazardous short circuits over time due wear-and-tear conditions prevalent inside electrical enclosures housing multiple components operating simultaneously under load conditions typical seen across industry sectors relying heavily upon automated processes driven primarily through digitally controlled interfaces linked directly back centrally managed hubs monitoring real-time performance metrics essential safeguarding continuous uninterrupted service delivery standards expected
