B&B HESP4DR - Surge protector ( DIN rail mountable )

Model HESP4DR is designed to help protect against lightning strikes, power surges, and other types of voltage disturbances to components on a DIN rail. The HESP4DR offers three stages of protection starting with a gas discharge tube followed by a series resistor and finally a Transient Voltage Suppressor (TVS).
In order for a surge protector to work properly it is important to have a good connection to earth ground. The HESP4DR has a grounding screw, which provides a solid ground connection for the user.
