PCB Mount Ct Current Transformer 1mA 5mA Fully Enclosed

PCB Mount High-Precision Current Sensing Transformer

PCB Mount Type current sensing transformer A current transformer (CT) is a type of transformer that is used to measure alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary. Current transformers, along with voltage or potential transformers, are instrument transformers. Instrument transformers scale the large values of voltage or current to small, standardized values that are easy to handle for measuring instruments and protective relays. The instrument transformers isolate measurement or protection circuits from the high voltage of the primary system. A current transformer provides a secondary current that is accurately proportional to the current flowing in its primary. The current transformer presents a negligible load to the primary circuit.

Applications :

• Residual current circuit breaker
• Earth Leakage protection switch
• Leakage circuit protection Breaker
• Leakage circuit protection plug (Appliance Leakage Circuit Interrupter -ALCI)
• Current transformer can play the role of current conversion and electrical isolation.
• If the secondary fault occurs, it will not affect the (primary) main line operation, reducing the frequency of maintenance
• According to the design of the circuit, the transformer will be more in line with the operation needs of the product.

Features:

• Low profile, compact size, Epoxy resin encapsulated, fully enclosed.
• PCB mounting type, easy to fix and install.
• Wide linearity range for output current and low phase shift error.
• Customer specifications are available.
• Used in universal and be in good interchangeability.

Notes: Product specifications can be customized
