Selection & installation notes
- The source lists 6–220 VDC and 6–440 VAC as family coil options; these are not the input range of one relay. Match the ordered coil to its supply.
- The source associates 380 VAC coils with 380–440 VAC yet limits short-time voltage to 110% of nominal. Confirm this variant range before applying an upper-end supply.
- Use a manufacturer load curve for DC voltages above 30 V or inductive and motor loads. The maximum voltage and current cannot be combined into a load rating.
- Confirm soldering process, conductor sizing, mounting drawing and operating/release times, which are not supplied. LED and suppression are custom options, not included in standard codes.
Based on the official Chinese product page and selection charts ↗. Checked 2026-09-15. Confirm the current specification for the exact model when ordering.
