Description

<p>When it comes to safeguarding your motors, reliability and precision are paramount. Our Motor Protection Relay stands as a robust solution designed for industrial and commercial applications where dependable motor protection is crucial. Engineered with versatility in mind, this relay operates seamlessly across a range of voltages—110-130 VAC and 220-240 VAC—making it suitable for diverse electrical systems.</p><p>The relay accommodates a rated current of 4 A, ensuring it can handle moderate loads effectively while maintaining optimal performance at both 50 Hz and 60 Hz frequencies. With a rated impulse withstand voltage of 4 kV, the device demonstrates resilience against transient over-voltages, providing an added layer of security to your motor systems.</p><p>Its contact configuration features a 2CO (SPDT) setup, offering flexibility in control applications by allowing dual switching options per circuit. Installation is straightforward with its DIN rail mounting type and screw terminals that facilitate secure connections. The double-chamber cage connection terminals enhance the reliability of wire retention—a critical feature for minimizing maintenance needs in high-vibration environments.</p><p>In terms of environmental robustness, this relay boasts an IP20/IP50 degree of protection along with an IP3 degree of pollution rating. This means it&amp;#39;s well-suited for use in controlled environments where dust ingress is limited but not entirely absent. Furthermore, its operational temperature range from -40 to 85 degrees Celsius ensures consistent performance under extreme conditions.</p><p>Measuring at a compact width of 97 mm, height of 109 mm, and depth of just 30 mm, this unit fits neatly into crowded panels without compromising on functionality or ease-of-access during installation or servicing. Despite its small footprint, it packs significant capability into its lightweight design weighing only 0.163 kg.</p><p>Safety compliance is another hallmark; this relay adheres to several standards including CAN/CSA C22.2 No.14 for Canadian markets and multiple IEC/EN standards such as EN 50495 and UL508 among others—attesting to its global applicability and adherence to rigorous safety norms.</p><p>For enhanced operational monitoring, the integrated PTC Type A sensor provides precise thermal feedback while LED indicators in green, red, and yellow offer clear visual cues on status updates—simplifying diagnostics during routine checks or troubleshooting sessions.</p><p>Whether you&amp;#39;re looking to integrate into existing setups or planning new installations requiring reliable motor protection solutions that meet international standards—the features packed within our Motor Protection Relay make it an ideal choice for professionals seeking durability matched with cutting-edge engineering excellence.</p>
