The Phoenix Contact 2838898 is a base element for the VALVETRAB MS series of Type 2 surge arresters. It is specifically designed for 3-phase power supply systems where N and PE conductors are installed separately.
This base element features a robust PBT/PA housing with a V0 flammability rating and an IP20 degree of protection. It is designed for mounting on a standard 35 mm DIN rail and has a width of 70.80 mm, height of 51.50 mm, and length of 99.00 mm. The unit has 4 positions and operates within an ambient temperature range of -40 °C to 80 °C.
Electrically, it supports an arrester rated voltage of 450 V AC (L-L), 260 V AC (L-N), and 260 V AC (N-PE). The nominal load current is 80 A, with a maximum required backup fuse of 125 A (gL/gG). It offers a short-circuit resistance of 25 kA. Connections are made via screw terminals, supporting conductor cross-sections from 0.5 mm² to 35 mm² (solid) and 0.5 mm² to 25 mm² (stranded).
An integrated remote indicator contact is included, featuring a PDT switching function. This allows for monitoring of the surge protection status. The base element is WEEE/RoHS-compliant since January 31, 2006.
The arrester rated voltage is 450 V AC (L-L), 260 V AC (L-N), and 260 V AC (N-PE).
