Environmental Conditions 

Ambient temperature: - 40°C~+40°C (below 35°C within 24 hours)
Relative humidity: ≤95% (daily average) or ≤90% (monthly average)
Altitude:  ≤ 1000m
The operating mechanism is the trip-free stored energy type with independent opening and closing regardless of the operator's action. The operating mechanism is widely used in all VD4-R series circuit-breakers with frontal control.
The circuit-breaker can be remote controlled when fitted with dedicated electrical accessories (gearmotor, opening and closing release).
The operating mechanism, the three poles and the current sensors (if provided) are installed on a metal frame without wheels. The construction is particularly compact, sturdy and of limited weight.
VD4-R series circuit-breakers with lateral operating mechanisms are life-long sealed pressure devices.(Standards IEC 62271-100)
