概述 / Overview

SYTM3EL 系列智能型漏电综合保护断路器（以下简称断路器）是我公司研发生产的新一代一体式高新技术产品，拥有多项国家专利，符合国家电网管理
的各项智能化要求，是配合国家智能电网运行的首选产品。是集剩余电流继电器、塑壳式断路器集各种功能附件于一体的多功能综合断路器。塑壳式断路器
为主开关，分断能力高、分断时间准确。一体式配电综合保护断路器具有体积小，安装使用方便、动作值固定分档可调、操作简易、能适应各地用户、各种
环境、按需设定。通信型系列的产品采用 RS-485 通信口，能与电脑建立通信功能，实现远程参数的调整、信息查询及下载故障参数等功能。
产品具有数码显示型和液晶显示型两种控制器供选择。
产品具有短路、过电流、剩余电流、缺相、断零和特波等保护功能。同时具有剩余电流显示、实时负载电流显示、各相电压显示、产品分合闸指示、时间显
示和故障查询等功能。还具有剩余电流、欠电压、过电压、缺相保障引起的剩余电流动作断路器断开后自动重合闸功能。该产品适用于交流 50Hz，额定绝
缘电压 800V，额定工作电压 380/400V，额定电流 40A-800A 的配电网络中，用来分配电能、保护线路。
广泛用于三相四线中性点直接接地，TT 系统的低压电网，对人身触电危险提供间接接触保护，也可对线路或用电设备的接地故障、过电流和短路等进行保护。
广泛用于安装在非专业人员无法触及的无人设施，如城网、农网改造的电表箱（计量箱）和低压 JP 柜，配电变压器综合配电柜，高山转播台、基站、独立设备，
动力箱、交通灯系统的配电盘。
广泛用于由于暂时对地漏电或暂时电涌引起的瞬时漏电或电压故障导致产品动作的情况下，需要直接通过自动重合闸功能恢复供电，而无需借助操作人员的
手动操作。本剩余电流动作断路器可垂直安装（即竖装）亦可水平安装（即横装）。
产品符合标准：GB14048.2 GB/T22387。
SYTM3EL series intelligent leakage comprehensive protection circuit breaker (hereinafter referred to as circuit breaker) is a new generation
of integrated high-tech products developed and produced by our company. It has many national patents and meets the various intelligent
requirements of national power grid management. The preferred product for grid operation. It is a multi-functional integrated circuit breaker
integrating residual current relay and molded case circuit breaker with various functional accessories. The molded case circuit breaker is
the main switch, which has high breaking capacity and accurate breaking time. The integrated power distribution integrated protection circuit
breaker has small size, convenient installation and use, adjustable action value and adjustable gear division, easy operation, and can be
adapted to local users, various environments and on-demand settings. The communication series products adopt RS-485 communication
port, which can establish communication function with computer, realize remote parameter adjustment, information inquiry and download fault
parameters.
The product is available in two types: digital display type and liquid crystal display type.
The product has protection functions such as short circuit, over current, residual current, phase loss, zero break and special wave. At the same
time, it has the functions of residual current display, real-time load current display, phase voltage display, product closing and closing indication,
time display and fault inquiry. It also has the residual current, under voltage, over voltage, and phase loss guarantee. This product is suitable for
AC 50Hz, rated insulation voltage 800V, rated working voltage 380/400V, rated current 40A-800A in the distribution network, used to distribute
electric energy and protect the line.
Widely used for three-phase four-wire neutral point direct grounding, TT system's low-voltage power grid provides indirect contact protection
for personal electric shock hazard, and can also protect ground faults, overcurrents and short circuits of lines or electrical equipment.
Widely used in installation of unmanned facilities that are not accessible to non-professionals, such as urban nets, rural power grids (metering
boxes) and low-pressure JP cabinets, distribution transformers integrated power distribution cabinets, alpine relay stations, base stations,
independent equipment , power box, power distribution system of traffic light system.
Widely used in the case of product leakage due to transient leakage or voltage failure caused by temporary earth leakage or temporary surge,
it is necessary to restore power directly through the auto-reclosing function without manual operation by the operator. The residual current
operated circuit breaker can be installed vertically (ie, vertically) or horizontally (ie, horizontally).
The product meets the standard: GB14048.2 GB/T22387.
