855-5105/300-001 WAGO Industrial Automation Components

WAGO 855-5105/300-001 is a split-core current transformer designed for measuring current with a primary rated current of 300A and a secondary rated current of 5A. It features a rated continuous thermal current (Icth) of 100%, a rated short-time thermal current (Ith) of 60 x IN / 1s, and a rated surge current (Idyn) of 2.5 x Ith. The transformer operates at a rated frequency of 50...60 Hz and has a rated power (Sr) of 0.5VA. It is classified in accuracy class 1. For safety and protection, it is IP20 protected, can withstand a test voltage of AC 3kV, and is designed for a highest voltage for equipment (Um) of AC 720 Vrms. The connection accommodates a measurement conductor feedthrough of 2 x diam. 42mm and uses a cable type of 2 x 1.5mm2 with a cable length of 3m. The color code for connections is black = S1 and red = S2. It is designed for split-core (suspended) mounting, weighs 600g, and operates within an ambient temperature range of -10...+55°C, with storage temperatures ranging from -20...+70°C. The relative humidity tolerance is 5...85% (non-condensing), and it can operate up to an altitude of 2000m. It complies with EN 61869-1 / EN 61869-2 standards, carries a CE conformity marking, and meets RoHS compliance. The product is packaged individually in a box, originates from the Netherlands (NL), and has a customs tariff number of 85043180888.
