- SHT2 is a control device which trips a circuit breaker doubly from the outside. When SHT1 doesn't operate normally, it can trip a circuit breaker safely.
- Shunt coil 1: Install it at existing location.
- Shunt coil 2: Install it on the right side of the Shunt coil 1.
- It is not available with UVT coil when installing couble shunt coil.
1. Rated voltage and characteristics of Trip coil
| Rated voltage[Vn] | Operating voltage range[V] | Power consumotion[VA or W] | Trip time[ms] | ||
|---|---|---|---|---|---|
| DC[V] | AC[V] | Inrush | Steady-state | ||
| 24–30 | — | 0.6–1.1Vn | 200 | 5 | Less than 40ms |
| 48–60 | 48 | 0.6–1.1Vn | |||
| 100–130 | 100–130 | 0.56–1.1Vn | |||
| 200–250 | 200–250 | 0.56–1.1Vn | |||
| — | 380–480 | 0.56–1.1Vn | |||
- Note) Operating voltage range is the min. rated voltage standard for each rated voltage (Vn).
2. Specification of the wire
- Refer to the below table regarding the length and specification of wire when using trip coil with DC 24–30 [V] or DC/AC 48–60 [V] of rated voltage.
