Ammeter Digital Display
Function:
The primary current of breaker is measured as 0.3 second sampling. Each phase current is displayed sequentially for 2 second and relevant phase is indicated by indication lamp of R.S.T.
Feature:
High bright & high accuracy digital type 3-ph ammeter.
Overcurrent Relay
Function:
Overcurrent is monitored and protected with characteristics of long-time delay, short-time delay and instantaneous settings.
Feature:
Overcurrent Relay is fitted with digital type one-chip micro processor. Pick-up current and time delay are set by simple bar-type connector. Self-diagnosis function is provided for highly reliable performance. The cause of tripping can be easily identified
Ground Relay
Function:
Ground fault is detected by using of internal CT or eaernal ZCT.
Features:
Off function is provided.
Overvoltage Relay & Undervoltage Ralay
Function:
Ovevoltage and undervoltage is protected.
Features:
Self-test function is provided. Time delay setting of max 2 seconds can be possible. When voltage reaches 85 ~ 105% of rated voltage, Relay will be restored.

Characteristics

Neutral Pont Method

When transfer is accompanied by uninterruptted power to the load, it is recommended to transfer after checking circuit stability rather instant transferring in case of power failure or reatoration . In order to meet these requirments, positioning at netral point (off-position) can be set by tripping mechanism as follows. A=>off=>B,B=>off=>A,and A=>off=>A,B=>off=>B and also ,instantaneous transfer can be performed by operating signal.

One-Coil Application

One-coil is employed for the transfer of normal power source and emergency power source.

Compact & Lightweight Design

Compact &lightweight design makes the mounting space minimized and the installation easier.

Excellent Breaking Capacity

It is designed for large arc-extinguishing chamber sufficient enough to interrupt large amount of arcing current. Arc-extinguishing contacts are designed for easier inspection and maintenance.

Superior Contacting Capacity

The contacting mechanism is designed to ensure steady and stable contacting performance against any abonormal or excessive current.

Construction for Safety

For safe operation, molded construction is employed on breaking parts. And also, Latching indicator is prepares to indicate the latching condition.
