Product Description
Conventional SPDs suffer false tripping and performance degradation in cold workshops or sealed high-temperature cabinets. This 4-pole Type 2 surge arrester maintains consistent performance from -40℃ to +70℃, equipped with dedicated low-temperature thermal release to avoid unnecessary disconnection under extreme cold. 40kA surge capacity and ≤25ns response time remain consistent regardless of ambient temperature shifts, with stable residual voltage clamping. PA6 V0 mineral nylon housing resists leakage and deformation under high humidity, anti-vibration pluggable modules fit industrial cabinets with frequent temperature swings, suitable for cold northern factories and sealed hot electrical rooms.
Key Features
Consistent surge protection performance across full -40℃ ~ +70℃ temperature spectrum
Specialized low-temperature release prevents false tripping in frigid environments
Minimal shift in response time and residual voltage under extreme hot/cold conditions
V0 flame retardant housing withstands long-term high heat inside sealed cabinets
Stable operation under 95% relative humidity for damp enclosed electrical rooms
FAQ:
Q1: Will long-term operation at -40℃ shorten service life?
A: All internal components and thermal release structures are engineered for wide temperature tolerance; continuous low-temperature operation does not accelerate aging.
Q2: Can it run continuously when sealed cabinet temperature hits 70℃ in summer?
A: Rated maximum operating temperature is 70℃; stable long-term performance is guaranteed with proper cabinet ventilation.
Q3: Is it suitable for indoor auxiliary cabinets with frequent temperature swings near outdoors?
A: IP20 rating limits installation to fully indoor enclosures (no open-air exposure); indoor auxiliary cabinets with fluctuating ambient temperatures are acceptable.
