Smart Residual MCCB(Photovoltaic Type) TDK3ELG

Model and Meaning

Main Technical Parameters

Core Features

Equipped with a high-performance 32-bit ARM microprocessor, it can process signals in real time and implement intelligent control to ensure operational response speed and accuracy.
Equipped with LCD Chinese/English display, the human-computer interaction interface is clear and friendly, the operation process is simple and easy to understand, and the usage threshold is lowered.
For residual current (leakage) protection, it supports online setting of residual current gear and has a reclosing function to improve fault handling efficiency.
It can monitor and track the residual current in the line in real time, automatically adjust the protection gear, ensure the continuous and stable operation of the product, and enhance operational reliability.
It has three-stage protection: long delay, short delay, and instantaneous. It adopts an electronic tripping design that is independent of the power supply voltage. The protection logic is more accurate and is not affected by voltage fluctuations.
The strong breaking capacity can reliably deal with line short-circuit faults, avoid fault expansion, and ensure the security of the power distribution network.
Integrated overvoltage protection, undervoltage protection, and phase loss protection functions fully cover voltage anomaly and phase failure scenarios.
It can display key operating data such as line residual current, three-phase power supply voltage, load current, etc. in real time, allowing users to intuitively grasp the line status.
Protection functions and related parameters can be set and modified online without powering off, improving operation and maintenance flexibility.
It can accurately identify and display trip types (including residual current, lockout, overload, undervoltage, overvoltage, and phase loss), and supports the storage, query, and deletion of trip records to facilitate fault tracing and analysis.

Optional Configuration

Network version: With communication functions, it can realize remote signaling (remote monitoring of equipment status), telemetry (remote collection of operation data), remote control (remote control of equipment start and stop), and remote adjustment (remote adjustment of parameters), adapting to the needs of intelligent power distribution management.
Lightning protection module: supports pluggable installation and can be flexibly selected according to the requirements of the use environment to enhance the equipment's ability to resist lightning strikes.
Infrared communication function: Data interaction can be achieved through infrared, which facilitates device debugging and data reading in specific scenarios.
