VS1-12 indoor side mounted circuit breaker 12kv(width 280mm)
product detail
- Pay attention to rated current. Its rated current can generally only be 1250A (under normal circumstances), if the larger current will generally choose formal fixed.
- Breaking short circuit current, its rated breaking short circuit current is generally only 31.5KA, the reason is the same as above.
3.Function: It can also lock, anti-jump and other functions
- On the interlock rod, you can extend left or right
- Spindle can be extended left or right
- Connect incoming and outgoing cables, either left or right. This is different from fixed formal wear.
Environmental conditions:
- Altitude: the altitude does not exceed 1000m;
- Ambient temperature: no higher than +40℃, not lower than -25℃;
- Relative humidity: the daily average does not exceed 95%, and the monthly average does not exceed 90%;
- Earthquake intensity: no more than 8 degrees;
- Locations without fire, explosion hazard, serious contamination, chemical corrosion and severe vibration.
