TPK-Iimp50kA Series DIN RAIL-IEC TYPE 1

Categories Type 1 Surge Protector, AC Surge Protector Brand: TrilPeak

Overview
The TPK-I-50 series is Trilpeak’s most robust line of Type 1/Class I lightning current arresters, engineered for direct lightning protection in facilities with external lightning protection systems (LPS). Th monobloc-format SPDs are capable of discharging extremely high impulse currents—up to 50 kA per phase and 100 kA on N-PE paths for TT systems—ensuring complete protection of main incoming power panels. Each model is specifically tailored for TNC, TNS, or TT earthing systems, offering remote signaling, PLC compatibility, and maintenance-friendly DIN-rail installation.

Features
■ Lightning impulse discharge current (Iimp): 50 kA per phase (10/350 µs waveform)
■ N-PE discharge current: up to 100 kA for TT configurations
■ Voltage protection level (Up): ≤ 2.0 kV
■ Response time: < 100 ns
■ Designed for primary surge protection in incoming main distribution panels
■ Dedicated models for TNC, TNS, and TT power systems
■ Compatible with Power Line Communication (PLC) networks
■ Optional remote signaling output (2-pin NO/NC contact)
■ Flame-retardant PA66 enclosure (UL94 V-0), IP20 rated
■ Operating temperature: -40°C to +80°C; up to 4000 m altitude
■ DIN-rail mountable monobloc design for quick installation and replacement

Standards and certifications
■ EN/IEC 61643-11 compliant
■ CE, RoHS certified
■ Class I SPD for direct lightning current protection

Applications
■ Primary protection at main power entry points in LPS-equipped buildings
■ Lightning surge defense in utility and industrial distribution cabinets
■ Surge shielding for mission-critical infrastructure (telecom, medical, UPS)
■ Smart grid environments with PLC-based monitoring and automation
■ Power transfer and control systems in exposed installation zones
