The ABB OVR T1-T2 N 100-255 C, order code 2CTB813012R2300, is a replaceable Type 1+2 surge protection cartridge designed for neutral-to-earth protection in compatible ABB OVR surge protection assemblies. Intended for low-voltage TT and TN-S electrical systems, it provides high-capacity protection against lightning currents and transient overvoltages.
Designed for systems with nominal AC voltages from 233–400 V AC, the OVR T1-T2 N 100-255 C has a maximum continuous operating voltage (Uc) of 255 V AC between N-PE. It provides a substantial 100 kA impulse current (Iimp) with a 10/350 µs waveform, alongside a 25 kA nominal discharge current (In) and 60 kA maximum discharge current (Imax) with an 8/20 µs waveform.
With a 1.5 kV voltage protection level, 100 kA short-circuit withstand capability and compact replaceable construction, the cartridge provides a straightforward way to restore compatible ABB OVR Type 1+2 surge protection devices after the protection element reaches the end of its service life.
Type 1+2 surge protection combines the ability to handle high-energy lightning-current impulses with protection against transient overvoltages generated by indirect lightning and switching events. Neutral-to-earth protection is particularly important within compatible TT and TN-S surge protection arrangements, providing a controlled discharge path between neutral and protective earth during transient events.
The ABB OVR T1-T2 N 100-255 C provides a 100 kA 10/350 µs impulse-current capability together with 60 kA maximum 8/20 µs discharge current. As a replaceable cartridge, it allows compatible ABB OVR assemblies to be serviced efficiently while retaining the existing SPD base and associated installation wiring.
