KL9540, KL9550 - Surge Filter Terminals

Overview

Surge filter terminals for the field supply and K-bus supply

The surge filter terminals include overvoltage filters for the K-bus (Bus Coupler) and/or field supply (power contacts).

The filters protect the components from line-bound surge voltages that can occur due to high-energy disturbance variables such as switching surges at inductive consumers or lightning strikes at the supply lines. The surge filter terminals can be used to protect the Bus Terminal station from damage in particularly hostile environments. The ship classification organizations stipulate the use of surge filters in shipbuilding applications and in the onshore / offshore sector.

The following types are available:

KL9540-0000 / KS9540-0000: Surge filter terminals for field supply
KL9540-0010 / KS9540-0010: Surge filter terminals for field supply of analog Bus Terminals
KL9550-0000 / KS9550-0000: Surge filter terminals for field supply and K-Bus supply
