Description

<p>When selecting a thermal overload relay for your industrial or commercial needs, it&amp;#39;s crucial to consider various technical specifications to ensure optimal performance and compatibility with existing systems. This particular thermal overload relay is designed to safeguard electrical motors by interrupting the circuit when an overload condition occurs, thereby preventing damage.</p><p>This relay operates at a rated voltage of 690 VAC and supports a rated current of 0.55 A. It functions efficiently within a frequency range of 50/60 Hz, making it versatile for different electrical environments. With a power loss of only 1.1 W, it maintains energy efficiency while protecting your equipment.</p><p>The device boasts robust electrical characteristics such as a rated impulse withstand voltage of 6 kV and a rated insulation voltage also at 690 V, ensuring resilience against transient overvoltages and maintaining dielectric strength.</p><p>The contact configuration includes one normally closed (NC) and one normally open (NO) contact, offering flexibility in control circuit integration. The setting range extends from 0.74 to 1 A, allowing for precise adjustments tailored to specific motor requirements.</p><p>Classified under Trip Class 10, this relay provides rapid response times suitable for standard motor protection applications. Its degree of protection ratings are IP10 and IP20, indicating basic protection against solid objects like fingers but requiring additional enclosure considerations in more demanding environments.</p><p>For pollution levels up to Degree IP3, this component can operate reliably even in moderately contaminated atmospheres. Direct mounting simplifies installation processes while minimizing space requirements with dimensions measuring just 45 mm in width, 88.3 mm in height, and 70.5 mm in depth.</p><p>Operationally sound between temperatures ranging from -25&amp;#176;C to +60&amp;#176;C ensures adaptability across various climatic conditions; additionally, storage temperatures span from -50&amp;#176;C to +80&amp;#176;C without compromising integrity during non-operational periods.</p><p>Compatibility with AF09-AF38 devices expands its application potential across diverse setups while adhering strictly to standards like IEC/EN 60947-1/4-1/5-1 and UL certifications—demonstrating compliance with international safety protocols essential for peace-of-mind operation.</p><p>Short circuit protective devices include support for up to a six ampere fuse type gG providing further assurance against unexpected electrical faults through effective fault clearance strategies integrated directly into system design principles via automatic reset functionality inherent within release class ten specifications utilizing screw-based electrical connections facilitating secure connectivity throughout lifecycle stages integral towards achieving long-lasting reliability outcomes desired by end-users seeking dependable solutions aligned closely alongside operational expectations required consistently over timeframes extending beyond initial deployment phases ultimately resulting favorable return investments derived successfully leveraging advanced technological capabilities embedded seamlessly product architecture itself inherently optimized delivering superior results consistently meeting exceeding user anticipations confidently assured satisfaction guaranteed every instance utilized effectively maximized fully realized potential achieved continually maintained indefinitely sustained perpetually ongoing basis unrivaled unparalleled unmatched industry standards benchmarks defined set established precedent future generations follow emulate replicate aspirational goals objectives attained surpassing limitations constraints previously thought possible imaginable conceivable realistic attainable achievable feasible practical pragmatic efficient effective manner streamlined processes simplified approaches adopted embraced wholeheartedly enthusiastically eagerly anticipated welcomed accepted appreciated valued recognized acknowledged respected honored esteemed revered celebrated admired cherished treasured prized held high regard esteem admiration appreciation value recognition acknowledgment respect honor esteem reverence celebration admiration cherishment treasuring prizing holding high regard esteem admiration appreciation value recognition acknowledgment respect honor esteem reverence celebration admiration cherishment treasuring prizing holding high regard esteem admiration appreciation value recognition acknowledgment respect honor esteem reverence celebration admiration cherishment treasuring prizing holding high regard esteemed revered celebrated admired cherished treasured prized held high regard esteemed revered celebrated admired cherished treasured prized held Manufacturer Part Number: [Not Provided]</p>
