2CTB815708R2600 ABB OVR T2 80-275s C QS Type 2 Surge Protection Cartridge

Why Choose the ABB OVR T2 80-275s C QS Surge Protection Cartridge?

The ABB OVR T2 80-275s C QS, order code 2CTB815708R2600, is a replaceable Type 2 / Class II surge protection cartridge from the ABB OVR QuickSafe range. Designed as a single-pole phase cartridge for compatible ABB OVR pluggable surge protection assemblies, it provides high-capacity protection against transient overvoltages associated with indirect lightning and electrical switching events.

ABB's surge protection catalogue specifies a 30 kA nominal discharge current (In) and an 80 kA maximum discharge current (Imax) with an 8/20 µs waveform for the OVR T2 80-275s C QS. The cartridge is rated for a 230 V AC nominal voltage, has a 275 V AC maximum continuous operating voltage (Uc) and provides a 1.8 kV voltage protection level (Up).

The cartridge incorporates ABB's Safety Reserve concept and visual condition indication, helping maintenance personnel identify the operating state of the protection element. Its removable cartridge construction allows a compatible OVR QuickSafe SPD to be restored without replacing or rewiring the complete surge protection assembly.

High-Capacity Type 2 Replacement Surge Protection

Type 2 surge protection devices are intended to limit transient overvoltages produced by indirect lightning effects and electrical switching events in low-voltage installations. They are typically incorporated into distribution boards, where surge current is diverted away from downstream electrical and electronic equipment. A pluggable SPD architecture separates the permanently wired base from the replaceable protection element, simplifying maintenance after the cartridge reaches the end of its service life.

The ABB OVR T2 80-275s C QS is the phase replacement cartridge used across compatible high-capacity ABB OVR QuickSafe assemblies. Its 80 kA maximum discharge capability, 275 V AC Uc rating and Safety Reserve functionality make it suitable for maintaining ABB OVR installations where high Type 2 surge-current capability and replaceable protection modules are required.

Typical Applications

• Replacement cartridge for compatible ABB OVR T2 QuickSafe surge protection devices.
• 230/400 V AC low-voltage electrical systems.
• Compatible TT electrical distribution systems.
• Compatible TN-C electrical distribution systems.
• Compatible TN-S electrical distribution systems.
• Main electrical distribution boards.
• Subdistribution boards.
• Commercial and industrial electrical installations.
• Maintenance of high-capacity ABB OVR Type 2 surge protection assemblies.
• Protection against indirect lightning and switching-induced transient overvoltages.
