Why Choose the ABB OVR T2 1N 40-150 P U Surge Protective Device?
The ABB OVR T2 1N 40-150 P U 2CTB802342R2000 is a Type 2 pluggable surge protective device (SPD) designed for single-phase low-voltage electrical networks. Part of the ABB OVR surge protection range, it helps protect electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning effects and switching events.
Designed for 120 V AC nominal systems, the OVR T2 1N 40-150 P U has a maximum continuous operating voltage (MCOV) of 150 V. It provides a maximum discharge current Imax of 40 kA and a nominal discharge current In of 20 kA, both based on the standard 8/20 µs surge-current waveform.
The 1N configuration is designed for single-phase networks and protects two lines using a MOV pole together with a neutral spark-gap pole. With a voltage protection rating (VPR) of 1.2 kV and a pluggable construction, the 2CTB802342R2000 provides a practical solution for surge protection in residential, commercial and industrial electrical distribution systems.

Reliable Type 2 Protection for Single-Phase Networks
Type 2 surge protective devices are used in low-voltage distribution systems to limit transient overvoltages and safely discharge surge currents before they can damage downstream electrical and electronic equipment. They are commonly installed in distribution boards and electrical panels as part of a coordinated surge protection system.
The ABB OVR T2 1N 40-150 P U combines a 40 kA Imax rating with a 20 kA In rating for robust surge-current handling. Its single-phase 1N architecture combines a MOV protection pole with a spark-gap connection to neutral, while the pluggable design supports convenient inspection and maintenance.
Typical Applications
- 120 V AC single-phase electrical distribution systems.
- Residential distribution boards.
- Commercial building electrical systems.
- Industrial electrical panels and switchboards.
- Automation and control equipment protection.
- Protection of sensitive electronic equipment.
- Low-voltage installations requiring Type 2 surge protection.
