This ABB surge protector (model 2CTB815710R0700) is designed for industrial and commercial three-phase electrical systems (3P+N). It offers robust protection against lightning and switching surges, significantly increasing equipment lifespan and service quality. While it provides comprehensive protection, it requires professional installation due to its electrical nature.

Its primary purpose is to protect three-phase electrical systems (3P+N) from damage caused by transient overvoltages, such as those from lightning strikes or switching operations.
It offers combined Type 1 and Type 2 surge protection, meaning it can handle both external surges (like lightning) and internal surges (from equipment switching).
Installation should only be performed by a qualified electrician. Working with electrical systems can be dangerous and requires specialized knowledge and tools.
It is designed for three-phase systems with a neutral (3P+N) and is compatible with TN-S and TT system configurations.
The device has an optic (visual) indicator that shows its operational status. It also features a remote signalling contact for monitoring system status.
The maximum continuous operating voltage (AC) for this device is 275V.
It has a nominal discharge current of 12.5kA (10/350 µs) and a maximum surge capacity of 80kA.
The surge protector may have operated due to a surge event and needs replacement. Consult a qualified electrician for inspection and replacement.
Check the wiring of the auxiliary contact to the monitoring system. Ensure the system is configured to receive the signal. Verify the surge protector is operational.
This is unusual and indicates a potential issue. Immediately disconnect power and have the device and system wiring inspected by a qualified electrician.
Setup: This device is designed for mounting on a standard 35mm DIN rail within an electrical enclosure. Connections should be made using appropriate conductors (up to 35mm² solid or 25mm² fine-strand). It is crucial that installation is performed by a qualified electrician according to local electrical codes and standards. Ensure the device is correctly wired to the three-phase lines and neutral.
Compatibility: The OVR T1-T2 3N 12.5-275s P TS QS is suitable for three-phase systems with neutral (3P+N) using TN-S or TT system configurations. Ensure the maximum continuous operating voltage of the system does not exceed 275V AC.
Care: The surge protector is largely maintenance-free. Regular visual inspection of the status indicator on the device is recommended. If the indicator shows a fault, the device may need replacement. Cleaning should only be done with a dry or slightly damp cloth, ensuring no moisture enters the device or connections.
