ECBD013 Smart Circuit Breaker

Description

The ECBD013 smart circuit breaker is suitable for AC 50Hz power systems, with a rated working voltage of 230V / 400V and a rated working current of 80A or below.

It is used to protect electrical equipment and circuits when overload, short circuit, or leakage occurs in the line.
The product features an attractive appearance, excellent and reliable performance, high breaking capacity, and fast tripping response.

It supports remote control and adopts a modular DIN-rail mounting design, making installation convenient.

The breaker is suitable for applications such as industrial control equipment, greenhouse irrigation, residential communities, villas, agricultural irrigation, breeding farms, water pumps, and rental properties.

Features

• High breaking capacity, ensuring reliable interruption under fault conditions.
• RS485 communication interface, enabling remote opening and closing, as well as remote parameter configuration.
• Remote locking and unlocking during maintenance. Mechanical locking is supported.
• Under voltage protection: The under voltage trip threshold can be set, or the undervoltage protection function can be disabled.
• Power-loss protection: When the under voltage function is enabled, the breaker will trip in the event of power loss. In this state, manual closing of the breaker is not permitted.
• Manual / Automatic mode selection: The operating mode can be set to either manual or automatic.
• Real-time electrical measurement: Real-time voltage, current, and power values can be read.
• Overvoltage withstand capability: The breaker can reliably operate under overvoltage conditions (N–L: 440V) without any damage to the product.
