VAL-MS-AR-T1/T2 75 - Lightning/surge arrester type 1/2
The VAL-MS-AR T1/T2 75 is a high-capacity SPD for Type 1 lightning as well as Type 2 switching surge currents, ideal for applications with both high load currents and high surge risk.VAL-MS BE-AR base provides a disconnect that separates the field wire from the protected mode for field diagnosis. Independent input and output terminals on the same side with ground terminals on the opposite end. All terminals are high-current screw clamping for stripped or ferruled, solid or stranded wires.
