Phoenix Contact 2909968

The surge arrester conforms to Type 2/Class II standards and is intended for use in three-phase power supply networks, specifically in configurations where the protective earth (PE) and neutral (N) are combined within one conductor, following a four-conductor system including L1, L2, L3, and PEN. The model VAL-SEC-T2-3C-440-FM features a remote indication contact for fault signaling, enhancing operational reliability.

Manufactured in Germany, this device is designed as a DIN rail module with a two-section, divisible structure, accommodating three positions. It operates within a wide voltage range of 5 V AC to 250 V AC and supports an operating current of 5 mA AC to 1 A AC. The maximum continuous operating voltage is rated at 440 V AC, with a nominal voltage of 400/690 V AC.

In terms of surge protection, the arrester can handle a nominal discharge current of 20 kA and a maximum discharge current of 40 kA, complying with IEC test classification II. The voltage protection level is ≤ 1.9 kV, ensuring effective safeguarding against transient overvoltages.

Additionally, the arrester is constructed from PA 6.6-FR 20% GF material, classified under flammability rating UL 94 V-0, and exhibits a degree of protection rated at IP20. It supports operational temperatures ranging from -40 °C to 80 °C and is designed for ambient humidity levels between 5% and 95%. The shock and vibration resistance ratings of 30g and 5g respectively further add to its durability in challenging environments.
