Description

<p>This product is designed to meet the demanding requirements of industrial and commercial applications, offering a robust solution for those who prioritize reliability and performance. It operates within a rated voltage range of 20-60 VDC, making it versatile for various power systems. The device supports multiple rated currents—2 A, 6 A, 4 A, and 3 A—accommodating diverse operational needs.</p><p>Engineered with a rated frequency of 50/60 Hz, this product integrates seamlessly into both domestic and international setups. Its rated impulse withstand voltage stands at an impressive 6 kV, ensuring resilience against transient overvoltages. Additionally, the product features a high-rated insulation voltage of 690 V which contributes to its overall safety profile.</p><p>The contact configuration is specified as 3NO (three normally open), suitable for straightforward control applications. With M4 screw terminal types, installation is simplified while maintaining secure connections. The degree of protection is IP20, indicating that it is protected against solid objects over 12 mm in size but not against water ingress.</p><p>Mounting this device is convenient due to its compatibility with standard 35 x 15 mm mounting rails—a common feature in electrical enclosures. For wiring purposes, both auxiliary and control circuits require a wire stripping length of just 10 mm each.</p><p>In terms of dimensions, the unit measures at a compact length of 77 mm by width of 45 mm and height of 86 mm—ideal for space-constrained environments without compromising on functionality. It can operate efficiently across extreme temperatures ranging from -40 to +70 degrees Celsius with an ambient temperature tolerance from -60 to +80 degrees Celsius.</p><p>Meeting rigorous standards such as IEC/EN 60947-1 and IEC/EN 60947-5-1 along with UL508 and CSA C22.2 No.14-13 approvals ensures compliance with industry norms providing peace-of-mind regarding quality assurance.</p><p>Weighing only .27 kg it’s lightweight yet durable enough to handle an air thermal current up to16 A while boasting substantial rated withstand currents between140 A &amp;amp;100A respectively depending on application specifics</p><p>Operating times vary slightly dependent upon conditions but generally fall within ranges like13–98ms or11–95ms among others allowing flexibility based upon situational demands</p><p>For those working within circuit voltages spanning24–60VACor20–60VDCthis component offers reliable performance tailored towards your specific system requirements</p>
