• Available in a wide variety of operating voltages, 75 V to 750 V • High impulse current capability using single MOV–480 V and 750 V versions comes with reduced impulse current • Sensitive state-of-the-art thermal disconnector • Back-up fuse up to 315 A gG, 750 V version comes with 250 A gG • Short circuit current rating up to 50 kA • Vibration and shock withstand capability • VDE-IEC Class I & II / EN Type 1+2 certified • All modules, also N-PE, with operating state green-red • Optional remote contact (RC) signaling The ProTec T1 series offers basic protection as a Type 1 surge protective device that comes with an extended maximum continuous operating voltage range span from 75 V to 750 V. Due to its Type 1 classification, the product can be installed between boundaries OA – 1 and higher. The varistor based protection module features outstanding short-circuit currents up to 50 kARMS without using a back up to a main fuse nominal current of 315 A. All modules are equipped with state-of-the-art thermal disconnector and life-status monitoring (green-red). Due to a unique vibration-proof locking mechanism design, these products are suitable for use in high vibration environments. An optional remote contact (RC) feature offers a three-pole remote signaling terminal to remotely monitor the operating state of the device.
