The Eaton SPD250400Y2J is a three-phase surge protector designed to safeguard against electrical surges in a variety of modes, including line-to-neutral, line-to-line, line-to-ground, and neutral-to-ground. This device operates within a temperature range of -20 to 50 degrees Celsius and is suitable for use at a nominal line voltage of 230VAC/400VAC and a nominal line current of 20kA. The SPD250400Y2J can handle a maximum surge current of 200kA and features a clamping voltage of up to 1000VAC at line-to-neutral, 1200VAC at line-to-ground, 900VAC at neutral-to-ground, and 1800VAC at line-to-line. It provides a 50% attenuation of electrical surges and operates at a frequency of 50 or 60 Hz.
