Product Description
This 4-pole AC power surge arrester fits LPZ0B to LPZ1 lightning protection zones and indoor three-phase low-voltage distribution cabinets. It diverts lightning surges and grid switching transients, clamping residual voltage ≤1.25kV to protect PLCs, control panels and precision electronic equipment. The pluggable anti-vibration module comes with built-in ultra-low temperature thermal release, visual deterioration indicator and NC/NO remote signalling contacts. Operating temperature ranges from -40℃ to +70℃ with IP20 indoor enclosure, compatible with 2.5~25mm² cables, suitable for power distribution systems in commercial buildings and small.
Key Features
Full-mode L1/L2/L3/N-E protection circuit
Response time ≤25ns for fast transient clamping
Visual status window + remote alarm contact
Wide temperature range for harsh indoor cabinet environments
V0 flame retardant housing for cabinet fire hazard reduction
FAQ:
Q1: Which lightning protection zones is this SPD suitable for?
A: It is only designed for indoor installation in LPZ0B to LPZ1 secondary zones, not for primary direct lightning protection.
Q2: What load capacity do remote signalling contacts support?
A: Rated 125Vac/1A, 125Vdc/0.2A, max wiring cross-section 2.5mm² for signal cables.
Q3: How to replace damaged modules?
A: Modular pluggable design allows single module replacement after power cut without removing the whole base unit.
