Type 3 surge protection device (SPD) for transient overvoltages monobloc design. The DIN V 3A range is suitable for very fine protection of sensitive equipment.
* Suitable as the final stage of protection in panels that have Type 2 surge protection devices installed upstream. The residual voltage of these devices is lower (finer protection) than that of Type 1 or 2 protectors. They should be installed as close as possible to the equipment being protected.
* Series connection, internal multistage protection for applications up to 3 A nominal current.
* Especially suitable for protection of 24 V or 12 V power supplies, for installation in the secondary of the power supply (AC/DC).
* They occupy a single module, ideal for limited spaces.
