About this item
Wide-temperature 2-pole single-phase Type2 surge arrester designed for indoor cabinets with large temperature fluctuations, rated from -40℃ frigid to 70℃ sealed high-temperature enclosures, different from standard secondary SPDs limited to 60℃ max. Surge capacity, residual voltage and thermal trip performance remain consistent through hot-cold cycling. Dual protection circuit with 20kA nominal and 40kA maximum discharge current, built-in dedicated ultra-low temperature thermal release prevents unnecessary circuit disconnection in cold ambient while isolating faulty modules automatically under high heat overload. Equipped with green-red status window and passive remote contacts, PA6 V0 flame retardant housing, plug-in 35mm DIN rail design with multiple Uc grades, suitable for cold northern retail shops, unventilated summer distribution boxes, warehouse single-phase panels and residential solar inverter cabinets with extreme temperature shifts.

FAQ
Q1: What does your company do?
A1: We are a high-tech enterprise specializing in the research, development, manufacturing, sales,and installation services of lightning arresters and related products.
Q2: What products do you offer?
A2: Our product range includes ultra-low residual voltage lightning arresters, lightning protection boxes, modules,composite lightning arresters, signal lightning arresters, and more.
Q3: Which industries do your products apply to?
A3: Our products are widely used in industries such as telecommunications, power, petroleum, transportation, and security.
Q4: Do you accept OEM and ODM orders?
A4: Yes, we welcome OEM and ODM cooperation to provide customized solutions.
Q5: Can it run continuously at 70℃ inside fully sealed zero-ventilation cabinets?
A5: 70℃ is the maximum rated operating point; basic cabinet ventilation guarantees long-term stable performance.
Q6: Will thermal trip falsely activate in -40℃ cold storage rooms?
A6: Custom low-temperature mechanism only triggers disconnection upon module overheating failure, no false action under normal cold ambient.
Q7: Does wide-temperature construction increase overall module width?
A7: Fixed 36mm standard 2-pole DIN footprint matches regular Type2 SPD dimensions without extra cabinet space occupation.
