The ABB eOVR T1-T2 3N 12.5-440s, order code 2TAM913100R5811, is an intelligent combined Type 1 and Type 2 surge protection device (SPD) designed to protect three-phase low-voltage electrical installations against lightning currents and transient overvoltages. As part of the ABB eOVR digital surge protection range, it combines high-energy surge protection with connected monitoring functions for modern electrical distribution systems.
Designed with a 3+1 protection configuration, the eOVR T1-T2 3N 12.5-440s is suitable for three-phase systems with neutral and has a nominal system voltage of 400/690 V AC. It provides an impulse current rating (Iimp) of 12.5 kA using the 10/350 µs lightning-current waveform, together with a nominal discharge current (In) of 20 kA and maximum discharge current (Imax) of 80 kA.
The device has a maximum continuous operating voltage (Uc) of 440 V AC and a voltage protection level (Up) of 1.4 kV. In addition to surge protection, the eOVR platform provides digital monitoring of protection status and surge events, allowing electrical-system operators to obtain greater visibility of SPD condition through compatible ABB monitoring infrastructure.
Combined Type 1 and Type 2 surge protection devices are designed to manage both high-energy lightning-current impulses and switching or induced transient overvoltages. The ABB eOVR T1-T2 3N 12.5-440s combines these protection stages in one coordinated device, making it suitable for installation in distribution systems where robust lightning and surge protection is required.
The eOVR platform adds digital intelligence to conventional surge protection by providing information about the condition and operating history of the SPD. Event recording and remote monitoring capabilities help maintenance teams identify surge activity, assess protection-system condition and plan maintenance without relying solely on periodic visual inspection.
