Why Choose the ABB eOVR T2 3N 40-350 Surge Protective Device?
The ABB eOVR T2 3N 40-350 (2TAM903100R4501) is a digital Type 2 surge protective device (SPD) designed for three-phase electrical installations with neutral. Its 3+1 protection configuration provides coordinated transient overvoltage protection for 230/400 V AC systems, helping protect sensitive electrical and electronic equipment against surges generated by indirect lightning activity and switching events.
The eOVR T2 3N 40-350 provides a 40 kA maximum discharge current (Imax) and 20 kA nominal discharge current (In), both based on the 8/20 µs surge-current waveform. It has a maximum continuous operating voltage Uc of 350 V and a voltage protection level Up of 1.5 kV, making it suitable for Type 2 protection within low-voltage distribution systems.
ABB’s eOVR platform adds digital monitoring to conventional surge protection. The device can record 20 surge events and 10 SPD remote-signal status changes and provides Modbus RS-485 communication. Integration with ABB InSite Pro M and ABB Ability solutions supports remote visibility, maintenance planning and monitoring of surge protection status within connected electrical installations.

Reliable Type 2 Protection with Digital Monitoring
Type 2 SPDs are used within low-voltage installations to limit transient overvoltages and divert surge current before damaging voltage levels can reach downstream electrical and electronic equipment. They are particularly suited to protection against indirect lightning effects and switching transients and are commonly installed in main or sub-distribution boards according to the overall surge protection design.
The ABB eOVR T2 3N 40-350 combines this protective function with intelligent monitoring. Its 40 kA Imax, 20 kA In and 1.5 kV Up provide defined surge-protection performance, while event recording and Modbus RS-485 connectivity provide additional information for inspection, maintenance and connected electrical-management applications.
Typical Applications
- Three-phase electrical systems with neutral.
- Main and sub-distribution boards requiring Type 2 surge protection.
- Commercial buildings and facilities.
- Industrial electrical distribution systems.
- Protection of automation, controls and sensitive electronic equipment.
- Connected installations using ABB InSite Pro M or ABB Ability.
