Selection & installation notes
- This is the standard CSH3B series, distinct from the -K series. Verify the complete model and AC/DC supply before connection.
- The source simultaneously claims Class II construction and requires earthing. The protective class and earthing arrangement need manufacturer confirmation; no resolved Class II claim is made here.
- Use ON/OFF control as specified in the source. Confirm inrush, overcurrent protection, clearances and thermal protection for the exact heater.
- Reference dimensions are approximate and must not be used as a fabrication drawing. Hot surfaces require suitable placement and protection.
Based on the official Chinese product page and selection charts ↗. Checked 2026-09-15. Confirm the current specification for the exact model when ordering.
