The ABB eOVR T1-T2 3N 12.5-275S, order code 2TAM913100R5411, is an intelligent combined Type 1 and Type 2 surge protection device (SPD) designed to protect low-voltage electrical installations against lightning currents and transient overvoltages. As part of ABB’s advanced eOVR digital surge protection range, it combines high-energy surge protection with integrated measurement, monitoring and communication functions.
Designed for three-phase systems with neutral, the eOVR T1-T2 3N 12.5-275S uses a 3+1 protection configuration and is rated for a nominal system voltage of 230/400 V AC. It provides an impulse current capability (Iimp) of 12.5 kA using the 10/350 µs waveform, a nominal discharge current (In) of 20 kA and a maximum discharge current (Imax) of 80 kA.
The device has a maximum continuous operating voltage (Uc) of 275 V AC and a voltage protection level (Up) of 1.4 kV. Its digital functionality enables monitoring of SPD condition and electrical parameters, helping facility operators assess protection status and plan maintenance through compatible ABB monitoring infrastructure.
Combined Type 1 and Type 2 SPDs are designed to handle both high-energy lightning currents and lower-energy transient overvoltages within low-voltage installations. The ABB eOVR T1-T2 3N 12.5-275S provides this coordinated protection in one device, making it particularly suitable for installation near the origin of an electrical installation where lightning-current protection is required.
The eOVR platform extends conventional surge protection through integrated digital monitoring. It can monitor parameters including overvoltage and undervoltage conditions, SPD remaining lifetime, ambient temperature, surge-event count and earth-connection status. This information can be presented through compatible ABB Pro M InSite infrastructure, enabling maintenance teams to assess SPD health without relying solely on periodic visual inspection.
