ABB’s OVR T1-T2 25kA marks our most advanced range of surge protective devices. In fact, this SPD is suitable for installations with prospective short-circuit current of up to 100 kA. Peace of mind has never been so powerful.
- OVR T1-T2-T3 25kA, OVR T1-T2 QS 12.5 kA as well as OVR T2 QS, in Imax=80kA, 40kA and OVR T2-T3 QS Imax=20kA in multi-pole versions for all distribution systems TT, TN-C, TN-S, IT and several voltage levels (255/275/350/440 V a.c)
- Different Iimp, Imax and Ifi protect installations against high transient overvoltages from lightning or switching effect
- Installation capabilities on sites with a prospective short-circuit current of up to 100 kA at installation point
