The Eaton SPD250480Y1J is a three-phase surge protector designed to safeguard against voltage spikes and electrical surges. With a nominal line voltage of 227 volts AC at 480 volts AC, this device is capable of handling high levels of electrical current, including a maximum surge current of 200 kiloamperes. The SPD250480Y1J offers comprehensive protection against various modes of electrical fault, including line-to-neutral, line-to-line, line-to-ground, and neutral-to-ground. Its nominal line current is 20 kiloamperes, and it features an attenuation of 50. This surge protector operates effectively within a temperature range of -20 to 50 degrees Celsius. It is designed to suppress voltage spikes up to 1000 volts AC in line-to-neutral configurations, 1200 volts AC in line-to-ground configurations, 900 volts AC in neutral-to-ground configurations, and 1800 volts AC in line-to-line configurations.
