Categories Type 1+2 Surge Protector, AC Surge Protector Brand: TrilPeak

Overview
The TPK-I-25 series represents the most robust range of Type 1+2/Class I+II surge protection devices, engineered to discharge lightning currents from direct strikes and induced surges. Designed for high-risk locations with external lightning protection systems (LPS), these SPDs feature a compact monobloc format and are tailored for TNS, TNC, and TT power systems. They ensure reliable primary protection in incoming distribution panels, offering PLC compatibility, fast response times, and optional remote monitoring.

Features
■ High lightning discharge capacity: Iimp 25 kA per phase (10/350 µs)
■ N-PE impulse current up to 100 kA for TT systems
■ Voltage protection level (Up): ≤ 1.5–2.0 kV
■ Response time: < 25 ns (L-N), < 100 ns (N-PE)
■ System-specific models for TNS, TNC, and TT configurations
■ Remote signaling contact (NO/NC, optional) for fault detection
■ Compatible with PLC networks, no signal interference
■ One-piece monobloc housing with compact DIN-rail mounting
■ Flame-retardant PA66 enclosure (UL94 V-0), IP20, -40°C to +80°C operating range
■ Designed for indoor installation, up to 4000 m altitude

Standards and certifications
■ IEC/EN 61643-11 compliant
■ CE and RoHS certified
■ Class I+II SPD for lightning-prone zones

Applications
■ Primary surge protection for main incoming power panels
■ Distribution cabinets in industrial and utility sectors
■ Surge shielding for telecom, medical, and UPS systems
■ Smart grid and PLC-driven automation systems
