DL-10 Series Current Relay Product Introduction (English)
The DL-10 series current relay is an electromagnetic instantaneous over-current protection device designed for secondary circuits in power systems. It is widely used as a reliable triggering component for overload and short-circuit protection in motors, transformers, and transmission lines. Utilizing electromagnetic operation principles, it responds swiftly to current fluctuations – achieving activation within 0.12 seconds at 1.1 times the set value and 0.04 seconds at double the value. The product line includes variants like DL-11, DL-12, and DL-13, featuring adjustable current ranges through series/parallel coil configurations. With contact capacity of 50W breaking power under 250V DC (5A inductive load) and 50,000 operational cycles, it ensures durable performance. The relay s insulated terminals withstand 2000V AC dielectric tests, while its compact structure supports front/rear wiring for flexible panel integration. Ideal for industrial applications, it combines rapid response with robust construction for essential circuit protection.1418

Technical Features & Construction
Featuring a transparent housing for visual status monitoring, the relay s electromagnetic mechanism incorporates a spiral spring adjustment system for precise current setting. Its dual-coil design enables range expansion via series/parallel switching with terminal links. The contact system (e.g. 1NO+1NC in DL-12 model) employs bridging slides for reliable switching, operating without auxiliary power while consuming <7VA. With ≥0.8 return coefficient and -25℃ to +40℃ temperature tolerance, it suits rapid fault interruption in substation protection panels, switchgear, and industrial control circuits. The modular construction allows vertical panel mounting with 87.5×89mm cutout dimensions, compatible with standard DIN rail accessories.111826
