ZPU5-T2-40AC Type 2 AC surge protective device with Imax 40kA, In 20kA, pluggable design, and 150V to 440V options for low-voltage distribution protection
ZPU5-T2-40AC Type 2 AC surge protective device for low-voltage distribution systems, with Imax 40kA, In 20kA, Class II protection, pluggable design, and voltage options from 150V to 440V.
Zivopower ZPU5-T2-40AC is a Type 2 AC surge protective device designed to protect electrical systems against transient overvoltage caused by fast switching operations or indirect lightning strikes. It is suitable for use in low-voltage distribution panels and can be applied as the second level of protection in systems equipped with Type 1 protectors, or as the first level of protection in applications that are not directly exposed to lightning strikes and do not have an external lightning protection system.
This SPD series supports voltage options of 150V, 275V, 320V, 385V, and 440V, with a maximum discharge current of 40kA and a nominal discharge current of 20kA. The product also supports remote signaling and adopts innovative tripping and breaking technology together with a pluggable housing design for easier maintenance and replacement.
ZPU5-T2-40AC is available in multiple pole configurations, including 1P, 2P, 3P, 4P, 1P+NPE, and 3P+NPE, making it suitable for TN-S, TN-C, and selected TT network systems depending on configuration.
