Product Description
Integrated non-detachable SPDs require full removal and complete rewiring upon failure, increasing maintenance time and loose wiring risks. This SPD adopts split base + independent pluggable module structure: when one module degrades, only the faulty unit needs extraction and replacement with all base, phase and PE wiring untouched to cut on-site wiring labor. Anti-loose locking buckles resist long-term cabinet vibration, while each single module integrates thermal release, visual status window and remote signalling contacts. 40kA surge capacity and ≤25ns response time comply with secondary lightning standards, streamlining routine maintenance for factory and commercial power distribution panels.
Key Features
Split base + pluggable modules eliminate full panel rewiring during replacement
Anti-loose locking structure prevents module loosening under continuous cabinet vibration
Front pull-out design enables operation in narrow compact electrical cabinets
Each module integrates full surge protection and status monitoring functions
Compatible with wide range of copper cable cross-sections 2.5~25mm²
FAQ:
Q1: Will repeated plug-in removal cause poor electrical contact?
A: Wear-resistant elastic conductive contacts maintain stable conductivity after multiple standardized replacement cycles.
Q2: Is full cabinet main power cut required for module swap?
A: Disconnect the circuit incoming breaker before plugging/unplugging modules to ensure operational safety.
Q3: Can spare modules be purchased separately instead of full complete units?
A: Single replacement modules are available separately; base units are reusable long-term to reduce spare part procurement costs.
