Description

<p>When selecting a thermal overload relay for your industrial or commercial needs, understanding the specifications and capabilities of the device is crucial. This particular thermal overload relay offers reliable protection and performance, ensuring your systems operate smoothly under various conditions.</p><p>Operating at a rated voltage of 690 VAC and suitable for both 50 Hz and 60 Hz frequency applications, this relay is versatile enough to integrate seamlessly into diverse electrical setups. It boasts a rated current of 0.55 A with a setting range between 2.3-3.1 A, providing flexibility in accommodating different operational requirements.</p><p>Designed with efficiency in mind, it features a power loss of only 1.1 W which helps in maintaining energy efficiency across your installations. The device&amp;#39;s rated impulse withstand voltage stands at an impressive 6 kV, offering robust protection against transient overvoltages.</p><p>The contact configuration includes one normally closed (NC) and one normally open (NO) contact, allowing for straightforward integration into control circuits. With its trip class set at Class 10, this relay ensures timely disconnection during overload conditions to protect connected equipment from damage.</p><p>Its degree of protection ranges from IP10 to IP20 depending on installation specifics, while the degree of pollution is classified as IP3 – making it suitable for environments where moderate contamination might occur.</p><p>Measuring just 45 mm in width by 88.3 mm in height and with a depth of 70.5 mm, this compact unit can be directly mounted onto compatible systems such as those using AF09-AF38 components without occupying excessive space.</p><p>The operating temperature range supports functionality from -25&amp;#176;C up to +60&amp;#176;C while storage temperatures can vary from -50&amp;#176;C to +80&amp;#176;C – showcasing resilience against extreme environmental conditions when not in use.</p><p>Compliance with international standards like IEC/EN 60947-1/-4-1/-5-1 and UL certifications underscores its reliability and quality assurance across global markets including Australia’s stringent regulatory landscape.</p><p>For enhanced safety during short circuit events up to currents of 10 A, it accommodates fuse type gG protective devices effectively managing potential risks associated with such incidents through its automatic reset function post-trip occurrences ensuring minimal downtime after resolving underlying
