ETEK EKU5-T1+T2-12 series represents a robust solution for combined Type 1 and Type 2 (Class I+II) surge protection, designed to safeguard low-voltage installations against transient overvoltages caused by direct or indirect lightning strikes and switching operations. Fully compliant with the IEC/EN61643-11 standard, this SPD ensures reliable protection for sensitive equipment.
Network Compatibility
The EKU5-T1+T2-12 is designed for various network configurations including TN-S, TN-C, and TT systems, making it a versatile protection solution for any electrical installation. The protection mode varies by model, with options for L-PE, N-PE, L-PEN, and L-N protection paths.
Safety & Reliability
Engineered with high energy Metal Oxide Varistors (MOV) and Gas Discharge Tube (GDT) technology, this surge protection device delivers consistent performance and long-term reliability. The visual status indicators provide easy verification of protection status, while remote signaling models offer integration with building management systems for continuous monitoring.
Applications
Designed for use in power distribution systems to protect electrical equipment from lightning or other transient overvoltage events. Ensures smooth operation in critical environments, including commercial buildings, healthcare facilities, and industrial plants.
