Item No.: HPT
HPT series low-voltage protection current transformers, low-voltage protection current transformers are mainly suitable for relay protection circuits passing through multiple busbars.
Description
Description
Introduce
 
This product was developed for protection systems that detect short-circuit faults. It has different accuracy classes and accuracy limit factors.
It can be extended to different perforation sizes and is widely used in low voltage distribution protection systems.
 
Applications
It is used to collect low-voltage overload and short-circuit signals, and is used with protection relays. 
The primary measurement range is 200-6300A, and the secondary output is 5A, 1A.
Collect low-voltage overload and short-circuit signals, which can be used in conjunction with the motor protection unit.
Used in places where there is no direct rain or snow, no serious pollution and severe vibration.
Features
Shell is made of flame-retardant, 140 temperature-resistant imported polycarbonate injection molding.
The iron core is made of directional cold rolled silicon steel strip.
The secondary conductor is high-strength electromagnetic enameled wire.
The product structure is novel, beautiful in appearance, easy to install,small in size, light in weight, high in accuracy, and large in capacity
