Phoenix Contact 2920094

The surge protection plug, designated as PT 1X2-24AC/FM-ST, is designed to safeguard electrical circuits with its integrated diagnostic and status indicator. This module is equipped with a remote indication contact that operates on a 2-wire floating signal circuit, ensuring effective monitoring of surge protection status.

Manufactured in Germany, this device complies with IEC test classification C1 and VDE requirement class C1, making it suitable for various industrial applications. The nominal voltage is rated at 24 V AC, with a maximum operating voltage of 250 V AC and a maximum operating current of 0.2 A. The compact dimensions of the plug, with a width of 17.7 mm, height of 45 mm, and depth of 52 mm, facilitate easy integration into existing systems.

With a surge protection fault message conveyed optically through its remote indicator contact, the plug ensures that any surge is promptly identified. The device supports flexible conductor cross-sections ranging from 0.2 mm² to 2.5 mm² and rigid cross-sections from 0.2 mm² to 4 mm². The housing is constructed from PA 6.6 material, rated V-0 for flammability according to UL 94 standards.

The surge protection capabilities include a nominal discharge current of 10 kA for both line-line and line-earth configurations, with a total discharge current capacity of 20 kA. The response times are exceptionally fast, with tA values of less than 1 ns for line-line and 100 ns for line-earth configurations, ensuring rapid mitigation of...
