Phoenix Contact VAL-MS-EE-T1/T2-3+0-335 DIN-Rail Combined Type 1/2 Lightning & Surge Arrester 3-Phase 335 V

The Phoenix Contact VAL-MS-EE-T1/T2-3+0-335 (Part No. 2910555) is a combined lightning (Type 1) and surge (Type 2) arrester engineered for 3-phase power supply networks with a common neutral/earth (4-conductor system: L1, L2, L3, PEN). This varistor-based plug-in device protects electrical installations, control panels, and sensitive equipment from damaging overvoltages caused by lightning strikes, switching surges, and grid transients.

Designed for quick DIN rail (35 mm) installation, the module offers coordinated surge protection in accordance with IEC Type 1 / Type 2 classification, providing both lightning current handling and transient voltage suppression with robust response behavior. It is ideal for industrial power distribution boards, buildings, and machinery that require layered overvoltage protection.
