2CTB815708R5500 ABB OVR T2 80-440s C QS Replacement Surge Protection Cartridge

Why Choose the ABB OVR T2 80-440s C QS Replacement Cartridge?

The ABB OVR T2 80-440s C QS is a high-performance replacement surge protection cartridge for compatible ABB OVR Type 2 QuickSafe surge protective devices. Identified by ABB order code 2CTB815708R5500, it provides a convenient means of restoring surge protection without replacing the complete DIN-rail-mounted SPD assembly.

Designed for phase protection in compatible ABB OVR assemblies, this cartridge combines an 80 kA maximum discharge current, 20 kA nominal discharge current and 2 kA impulse current. ABB QuickSafe technology incorporates status indication and preventive-maintenance functionality, helping maintenance personnel identify when a cartridge requires replacement.

With a 400 V AC nominal voltage, 440 V AC maximum continuous operating voltage and 1.4 kV voltage protection level, the OVR T2 80-440s C QS is designed for demanding commercial and industrial surge-protection applications. Its compact plug-in construction enables rapid replacement in compatible single- and multi-pole ABB OVR QuickSafe devices.

Convenient Maintenance for ABB OVR Surge Protection

Pluggable surge protective devices allow the active protection cartridge to be replaced independently of the installed base. The ABB OVR T2 80-440s C QS therefore helps reduce maintenance time when a compatible OVR QuickSafe SPD cartridge reaches the end of its service life, while retaining the existing wiring and DIN-rail-mounted assembly.

The cartridge is designed to handle transient currents with an 8/20 µs waveform and helps limit damaging transient overvoltages before they reach sensitive electrical and electronic equipment. Its visual status indication and preventive-maintenance capability make condition checking straightforward during routine electrical inspections.
