The JZB-100 series static intermediate relay with hold is designed as an auxiliary relay for DC protection loops, increasing the number and capacity of contacts of the main protection relay and improving reliability. Three models are offered: JZB-115 (current‑actuated, voltage‑hold), JZB-127 (voltage‑actuated, current‑hold) and JZB-138 (voltage‑actuated, current‑hold).
The leaflet lists the main technical parameters, internal terminal wiring diagrams, dimensions and mounting hole drawings, as well as ordering and maintenance instructions. Key data include rated voltages of 220 V, 110 V and 48 V DC, rated currents of 0.25‑4 A, power consumption not exceeding 3 W per circuit, and an electrical life of at least 10 000 operations. This manual is written in Chinese.
| Rated voltage | DC 220 V, 110 V, 48 V |
|---|---|
| Rated current | DC 0.25‑4 A |
| Power consumption | ≤3 W (voltage circuit), ≤3 W (current circuit) |
| Electrical life | ≥10 000 operations |
| Insulation resistance | ≥300 MΩ at 500 V |
The relay is rated for DC 220 V, 110 V or 48 V.
Each circuit (voltage and current) consumes no more than 3 W.
The relay’s electrical life is at least 10 000 operations under normal load.
Insulation resistance must be at least 300 MΩ when measured with a 500 V test voltage.
