2CTB815708R4000 ABB OVR T2 4L 80-440s P TS QS Type 2 Surge Protective Device

Why Choose the ABB OVR T2 4L 80-440s P TS QS Surge Protective Device?

The ABB OVR T2 4L 80-440s P TS QS is a high-performance Type 2 surge protective device (SPD) designed to protect three-phase low-voltage electrical installations and sensitive equipment against transient overvoltages caused by indirect lightning strikes and switching events. Identified by ABB order code 2CTB815708R4000, this four-pole device forms part of the proven ABB OVR QuickSafe surge protection range.

Designed for TN-S and IT electrical networks, the OVR T2 4L 80-440s P TS QS combines high surge-current capability with ABB QuickSafe technology, pluggable protection cartridges and mechanical status indication. The TS remote signalling function provides an auxiliary contact for monitoring the condition of the SPD from a control or supervisory system, making it particularly suitable for critical industrial and commercial installations.

With a rated system voltage of 400/690 V AC, a 440 V AC maximum continuous operating voltage, 80 kA maximum discharge current and 2.4 kV voltage protection level, this SPD provides robust protection for four-line electrical distribution systems. Its compact DIN-rail-mounted construction simplifies integration into main distribution boards, sub-distribution boards and industrial control panels.

Reliable Four-Pole Surge Protection

Type 2 surge protective devices are designed to limit transient overvoltages and safely discharge surge currents with an 8/20 µs waveform. Installed in an electrical distribution board, the ABB OVR T2 4L 80-440s P TS QS helps prevent damaging transient voltages from reaching sensitive downstream equipment, control systems and electronic devices.

The four-pole architecture makes this model suitable for three-phase installations requiring protection across four conductors. ABB's pluggable QuickSafe design supports efficient maintenance, while individual mechanical indicators provide local status information and the TS auxiliary signalling facility allows the SPD condition to be incorporated into remote monitoring systems.

Typical Applications

• Three-phase main electrical distribution boards.
• Commercial and industrial sub-distribution boards.
• TN-S electrical distribution systems.
• IT electrical networks.
• Industrial machinery and automation control panels.
• Manufacturing and process-control facilities.
• Building services and infrastructure installations.
• Protection of sensitive electronic and automation equipment.
• Installations requiring remote surge-protection status monitoring.
