TRANSTECTOR's I2R-75KD240 240 VAC, two-pole, delta, three-wire surge protection device (SPD). The I2R-75KD240 uses thermally protected metal oxide varistor (MOV) technology for industrial applications requiring 240 VAC, three-phase delta requirements. Through superior design, each I2R combines a robust 75 kA surge capacity that also eliminates back-up fusing requirements thus providing network operators with a quick to install, safe, and reliable product set for AC network surge protection.
