Specifications: Type: Surge Protection Device (SPD) Model: WATSNA-160/160-4CBR Current Rating: 160A Number of Poles: 4P (4 poles) – Suitable for four-wire systems, including live and neutral conductors Maximum Discharge Capacity: 160 kA (the maximum surge current the SPD can safely handle) Nominal Voltage (Un): Typically 400V (for three-phase systems) Voltage Protection Level (Up): Typically 1.5 kV (the maximum voltage level the SPD will allow during surge events) Nominal Discharge Current (In): Typically 40 kA (standard surge current the device is rated for during normal surge events) Rated Frequency: 50/60 Hz Response Time: Fast response time for quick disconnect during surge events Protection Features: Comprehensive Surge Protection: Provides protection for both live (L) and neutral (N) conductors, as well as other key parts of the system, from electrical surges. High Surge Capacity: The device has a 160 kA surge capacity, ensuring high-energy surge events, such as lightning strikes, are safely managed. Thermal Disconnect: In case of overheating, the SPD is designed to automatically disconnect, preventing any potential risk from extended surge exposure. Compliance: Complies with international standards such as IEC 61643-1 for surge protection devices and IEC 60364-5-53 for electrical installations.
