Gossen 1715V0190 ASK 31.3 Current transformer 400 / 5A 10VA, Kl.1

ASK plug-in current transformer for indirect measurement of sinusoidal alternating currents. CURRENT TRANSFORMER ASK31.3,400/5A,10VA,CL.1. Primary nominal currents from 75 A to 1500 A Secondary nominal current from 1 A or 5 A. Class accuracy: 1. The ASK plug-in current transformers transform high alternating currents - up to 1500 A (primary current) - into small, harmless, measurable currents (secondary current). Secondary currents are standardized and are either 1 or 5 A. At the same time, they galvanically isolate the primary circuit and the secondary circuit from each other. The plug-in current transformer is plugged onto the primary conductor. This saves time-consuming wiring work. The secondary side (usually a measuring device, a display or a control system) is connected with terminals. Plug-in current transformers are available from 75 A with various hole sizes for busbars or cables.
