The Phoenix Contact 2839415 is a surge protection base element designed for use with PT series protective plugs. This base element is part of a two-section, divisible DIN rail module, facilitating easy installation and maintenance. It is intended for mounting on a 35 mm DIN rail and has a housing width of 17.5 mm.
The device offers protection for a 4-wire floating signal circuit. It incorporates a gas-filled surge arrester between signal ground and earth ground. The output voltage limitation for a 1 kV/µs spike (Core-Earth) is specified as less than or equal to 600 V. The surge protection fault message is indicated as 'None'.
Connection is made via screw terminal blocks for both input and output. The recommended tightening torque for the M3 screw thread is 0.5 Nm. The operating ambient temperature range is -40 °C to 85 °C, and it has an IP20 degree of protection. The flammability class according to UL 94 is V0. The country of origin is Germany.
