EGSTON A5E01464797 Current Transformer

Overview

The EGSTON A5E01464797 is a precision current transformer designed for low voltage air circuit breaker metering and protection. The EGSTON A5E01464797 is manufactured by EGSTON System Electronics, a specialist in custom inductive components for industrial power distribution. The EGSTON A5E01464797 converts primary load current into a low secondary signal for electronic trip units, enabling overload, short-circuit protection and power measurement within the ACB. As a legacy spare component, the EGSTON A5E01464797 is widely stocked for maintenance and overhaul of existing switchgear assemblies.

Features

The EGSTON A5E01464797 is constructed with high-permeability magnetic core and insulated winding structure to deliver stable transformation accuracy across the rated current range. The EGSTON A5E01464797 provides isolated secondary current output to feed the electronic trip unit, separating high-power primary circuit from low-voltage control electronics. The EGSTON A5E01464797 integrates robust insulation and temperature resistance to withstand thermal cycling inside the breaker compartment. It is matched and calibrated with the original ACB frame and electronic protection release. The EGSTON A5E01464797 adopts compact embedded installation design and follows the original wiring definition for direct replacement during scheduled maintenance.

Specs

Device Type: Current Transformer Model: EGSTON A5E01464797 Manufacturer: EGSTON System Electronics Applicable Equipment: Low voltage air circuit breaker Function: Current sampling for protection and metering Insulation Structure: High voltage isolation winding Mounting: Built-in installation inside ACB Operating Temperature: -20°C ~ +70°C Protection Grade: IP20 inside switchgear compartment

Principle

The EGSTON A5E01464797 works based on electromagnetic induction. Primary load current passes through the magnetic core and induces proportional secondary current. The secondary signal is sent to the electronic trip unit for calculation of current magnitude, power and energy values. The trip unit uses this sampled data to execute LSI or LSIG protection logic. The EGSTON A5E01464797 maintains accurate signal conversion under normal operating conditions. Excessive overcurrent may cause core saturation and trigger breaker protection interlock.

Applications

The EGSTON A5E01464797 is used as internal current sensing component for low voltage air circuit breakers in industrial distribution rooms, power plants and commercial switchboards. It supplies current feedback signals for the electronic protection unit to realize reliable fault detection. The EGSTON A5E01464797 is commonly stocked as spare for emergency replacement and scheduled overhaul of legacy ACB switchgear. It also supports switchgear retrofitting and protection loop calibration projects.
