Description

Product Overview

A1-R-V2 adopts a 2P modular design and is compatible with standard DIN rail installation. It is a new generation of intelligent protection switch for the mid-range single-phase distribution market. The product is equipped with a high-performance microprocessor, which retains basic protection functions such as overload, short circuit, and leakage, while adding real-time voltage and current monitoring and RS485 communication capabilities. It can be connected to local energy management systems for centralized monitoring. Its simple operation design and stable performance meet the basic needs of users for intelligent upgrading of single-phase distribution systems, helping users improve distribution management efficiency and electricity safety at a lower cost.

Main Features

1. Precise single-phase protection system
Optimizing the protection curve for single-phase load characteristics, it has three core functions: overload inverse time protection, short-circuit instantaneous protection, and leakage classification protection. It supports custom action thresholds and delays, effectively balancing protection sensitivity and system stability; The power-off memory function ensures that parameters are not lost and automatically operates according to the original strategy after power is restored.
2. Real time status monitoring
Equipped with high-precision current and voltage sensors, real-time collection of key parameters such as voltage, current, and power, with a data update frequency of once per second, providing data support for energy efficiency analysis and fault prediction of the distribution system.
3. Multi level alarm mechanism
Support dual mechanisms of local sound and light alarms and remote platform alarms. When a fault occurs, the alarm is immediately triggered and the fault type and location information are uploaded, making it easier for operation and maintenance personnel to respond in a timely manner.
4. Industrial grade reliability
Adopting UL94 V-0 flame retardant shell, capable of withstanding high temperatures up to 1300 ℃; The contact system has undergone 50000 mechanical life tests and has an IP20 protection level. It supports operation in a wide temperature range of -10 ℃ to 50 ℃, meeting the stable operation requirements of general commercial and civilian scenarios.
5. Lightweight intelligent upgrade
No need to modify the original distribution architecture, simply replacing traditional circuit breakers can achieve intelligent upgrading, compatible with mainstream energy management system protocols, and reduce the time and capital cost of user intelligent transformation.
