Overview
The Phoenix Contact VAL-MS 230 ST is a Type 2 surge protection plug designed to protect electrical equipment from voltage surges and transient overvoltages. This surge arrester features a high-capacity varistor and is engineered for use with VAL-MS base elements on NS 35/7.5 rail-mounted systems. The 230 V AC rated design makes it ideal for industrial automation systems, control cabinets, and switchboard protection in three-phase and single-phase AC applications.
