Why Choose the ABB OVR T1-T2 1N 12.5-440s P QS Surge Protective Device?
The ABB OVR T1-T2 1N 12.5-440s P QS, order code 2CTB815710R4200, is a combined Type 1 and Type 2 surge protective device (SPD) designed to protect low-voltage electrical installations against lightning currents and transient overvoltages. Part of the ABB OVR QuickSafe range, it combines high-energy lightning-current protection with Type 2 transient surge protection in a compact, pluggable assembly.
The 1N configuration provides coordinated protection for a phase conductor and neutral path, making the device suitable for appropriate single-phase plus neutral electrical systems. Its pluggable design allows protection modules to be serviced or replaced when required, while integrated visual status indication provides a straightforward means of checking the SPD's operating condition.
With a maximum continuous operating voltage (Uc) of 440 V AC and an impulse current (Iimp) of 12.5 kA for the 10/350 µs lightning-current waveform, the OVR T1-T2 1N 12.5-440s P QS is engineered for demanding lightning and transient-overvoltage protection. ABB QuickSafe technology further supports dependable operation and practical maintenance within modern electrical distribution systems.
