<p>When it comes to safeguarding your electrical systems, a reliable thermal overload relay is essential. This particular model stands out with its robust specifications and compatibility with various applications, making it an excellent choice for industrial and commercial environments.</p><p>Designed to operate at a rated voltage of 690 VAC and a frequency of 50/60 Hz, this thermal overload relay ensures consistent performance across diverse settings. Its rated current is set at 0.55 A, which suits many standard operations while maintaining efficient energy use with a power loss of just 1.3 W.</p><p>The device boasts a rated impulse withstand voltage of 6 kV and the same value for insulation voltage, ensuring resilience against electrical disturbances. The contact configuration includes one normally closed (1NC) and one normally open (1NO) contact, offering flexibility in circuit design.</p><p>With Trip Class 10, this relay provides timely protection by tripping within ten seconds under conditions of six times the full-load current—ideal for motors that require prompt intervention to prevent damage from overheating.</p><p>In terms of construction, the relay offers degrees of protection IP10 and IP20 alongside pollution degree IP3 ratings. These ensure adequate safety measures against dust ingress while being suitable for less severe environmental conditions.</p><p>Installation is straightforward due to its direct mounting type. With dimensions measuring 45 mm in width, 76.7 mm in height, and 53.5 mm in depth, it fits comfortably into most setups without requiring excessive space.</p><p>Operational temperatures range from -25&#176;C to +60&#176;C, accommodating various climates or internal environments where temperature fluctuations might occur frequently. Additionally, it can be stored safely between -50&#176;C and +80&#176;C without compromising functionality upon reinstallation.</p><p>Compatibility-wise, this relay pairs well with devices such as B6 through VB7 series contactors as well as MC1 and MC2 models—offering versatility across different system requirements or upgrades you may have planned down the line.</p><p>Compliant with several standards including IEC/EN 60947-1/-4-1/-5-1 along with UL certifications like UL 60947-1/-4-1 plus IEC60335-2-40 A2L approval; rest assured knowing you&#39;re working within globally recognized safety parameters when integrating this component into your projects!</p><p>For short-circuit protection up to forty amps utilizing fuse type gG connections are made easy via screw terminals allowing secure attachment even under demanding operational scenarios often encountered within industry settings today!</p><p>Finally featuring automatic reset function means minimal downtime post-trip event so operations resume swiftly reducing potential productivity losses during critical periods needing uninterrupted service delivery!</p>
