JH series static reclosing relayDetailed product description：

1. Purpose:
JH series static reclosing relay is used as the main component in the three-phase primary reclosing connection of transmission lines

2. Characteristics
2.1 The DH series reclosing relay can be replaced without changing the wiring of the relay screen, as shown in Table 1;
2.2 Use a digital switch to set the reclosing delay time, with small scale error and high accuracy. Changing the setting value does not require recalibration;
2.3 Preparation time for reclosing, constant at 20 seconds, unaffected by external voltage and ambient temperature;
2.4 External startup reclosing, using optocoupler isolation. Good anti-interference performance.

3. Main technical data
3.1 DC rated voltage: 48V, 110V, 220V;
3.2 DC rated holding current of intermediate relay current coil: 0.25A, 0.5A, 1A, 2.5A;
3.3 The setting range of the time relay is 0.1S to 9.9S, with a step difference of 0.1s;
3.4 Power consumption
3.4.1 The power consumption of intermediate relays shall not exceed 8W for voltage coils at rated voltages of 110V and 220V, and 4W for current coils at rated current.
3.4.2 Except for intermediate relays, the total power consumption of reclosing relays shall not exceed 5W at 220V rated voltage and 3W at 110V rated voltage.
