JH1 Series User Manual

This manual covers the JH1 series terminal blocks, which are suitable for AC 50 Hz or 60 Hz systems with a rated voltage up to 690 V and DC up to 440 V. The blocks accept conductor cross‑sections up to 35 mm² and feature a compact, screw‑type connection for easy wiring and maintenance. They are mounted on G‑type rails and include protective covers, complying with GB/T14048.7 IEC60947‑7‑1 standards.

The document also provides ordering guidelines: specify the product model, conductor area, category, and quantity when placing an order. Standard terminal blocks are assembled from ten‑piece strips, and special requirements should be noted. Example: ordering "JH1‑2.5L 5" indicates model JH1‑2.5L, 2.5 mm² conductor area, ordinary type, and a quantity of five strips. This manual is written in Chinese.
