TK30N Measuring Current Transformer
TK30N – Measuring Current Transformer 40/5-600/5 A , Window Type 30×10 mm
The TK30N is a window-type measuring current transformer with a 30X10 mm window. It provides accurate current transformation for measurement in low-voltage electrical panels. Because of its compact size, it fits into panels with limited space. At the same time, it delivers stable and reliable measurement results.
Product Overview
The TK30N operates in low-voltage electrical systems. It has a 30X10 mm window opening. So, the insulated primary conductor passes through the transformer. Also, the design supports use in compact electrical panels.
Intended Use
The TK30N works with many measuring devices. These include analog ammeters, digital ammeters, energy meters, and power analyzers. As a result, it connects the secondary circuit to the measuring device.
Electrical Characteristics
The TK30N transforms the primary current within its rated operating range. It is available with 1 A or 5 A secondary outputs. It comes in different accuracy classes to meet metering needs. Also, The low VA burden allows the TK30N to connect to standard measuring devices without problems. As a result, the transformer delivers accurate and stable readings.
Installation Options
The TK30N supports DIN rail mounting with a dedicated clip. Installers can mount it in low-voltage panels. The insulated primary cable passes through the window opening. Panel wiring remains simple and safe.
The TK30N meets the requirements of IEC 61869-1, IEC 61869-2, and EN 61869-2 standards. It also complies with IEC 60044-1. In addition, the product conforms to VDE 0414-1, DIN 57414, BS 3938, and BS 7626 standards. The insulating materials pass the TS EN 60695-2-11 Glow-Wire Test. The enclosure meets IEC/EN 62262 impact resistance requirements. As a result, the product complies with CE and TSE regulations. ISO 9001:2015 ensures stable quality and controlled production. ISO 14001:2015 supports environmentally responsible manufacturing. Together, these standards help deliver safe insulation, correct clearances, and strong mechanical protection.
Construction and Safet
The TK30N uses a strong insulation system for safe operation in industrial environments. Moreover, a sealed terminal cover improves touch protection. High-quality terminals provide secure electrical connections. As a result, the transformer allows safe installation and reliable long term operation.
