Model 356M – 3-Pole Sealed Gas Tube Station Protector
Bourns® 356 type Station Protectors are designed to provide primary protection on conductors serving subscriber premises.
The Model 356M provides protection against lightning surges, power-cross conditions and ground potential rises.
The protector element consists of a balanced, heavy-duty-rated, 3-pole Gas Tube with an external backup gap and a unique switchgrade shorting mechanism for each line. The Gas Tube is sealed in a fire-resistant plastic body with plated #10 brass studs, washers
and hex nuts for connection to one subscriber pair. A plated brass ground connector is slotted to fit the ground connection points of
station protector housings and network interface devices.
