Phoenix Contact 2800183

The VAL-MS-T1/T2 335/12.5/3+1-FM is a plug-in lightning and surge arrester specifically engineered for 3-phase power supply systems with distinct neutral (N) and protective earth (PE) connections, employing a 5-conductor configuration: L1, L2, L3, N, PE. This arrester is suitable for installations requiring Lightning Protection Levels III and IV.

It operates effectively within a wide range of parameters, including a maximum continuous operating voltage of 335 V AC and a nominal voltage of 240/415 V AC. The device supports a rated load current of 80 A and features an optical remote indication contact for surge protection fault messages. The arrester's surge protection capabilities are substantial, with a nominal discharge current of 12.5 kA for both L-N and L-PE and a maximum discharge current of 65 kA.

Constructed from durable PA 6.6 housing material and designed for DIN rail mounting, the module occupies a width of 71.2 mm and a height of 98.7 mm. It is rated for operation in ambient temperatures ranging from -40 °C to 80 °C and complies with the IEC test classification I / II, ensuring reliable performance across various environments. The response times are optimized at ≤ 25 ns for L-N and ≤ 100 ns for both N-PE and L-PE, facilitating rapid surge response. The product is identified by the Designation Code VALVETRAB MS.
