Thermal Relay NR2-11.5/Z 0.4-0.63A — Compact Overload Protection for Low-Current Circuits
Thermal Relay NR2-11.5/Z 0.4-0.63A is a compact and reliable overload protection device designed for low-current electrical circuits. Functionally similar to contactors but smaller and rated for lower amperage (up to 0.63A), this CHINT Electrics relay is ideal for switching low-power signals and controlling circuits. It features a three-pole thermal bimetallic trip unit, adjustable trip current, temperature compensation, a trip indication, and a test button for easy functionality verification. This ensures robust and dependable circuit protection.
