概述 / Overview

SYTM3E 系列智能型塑壳断路器，是本厂采用国际先进设计、制造技术研制、开发的新型断路器之一。其额定绝缘电压为 800V，适用于交流 50Hz 额定
工作电压 400V，额定工作电流至 800A 的电路中作不频繁转换及电动机不频繁起动之用。断路器具有过载长延时反时限、短路短延时反时限、短路短延时
定时限、短路瞬时和欠电压保护功能，能保护线路和电源设备不受损坏。
SYTM3E series intelligent molded case circuit breaker is one of the new circuit breakers developed and developed by our factory using
international advanced design and manufacturing technology. Its rated insulation voltage is 800V, suitable for AC 50Hz rated working voltage
400V, rated working current to 800A in the circuit for infrequent conversion and motor infrequent starting. The circuit breaker has overload long
delay inverse time limit, short circuit short delay inverse time limit, short circuit short delay time limit, short circuit transient and under voltage
protection function, which can protect the line and power equipment from damage.
主要技术功能 / Main technical function
SYTM3E 系列智能型塑壳断路器具有三段保护功能，使用类别为 B 的断路器与连接在同一电路中的其它短路保护装置在短路条件下具有完全选择性配合：
具有三段保护动作电流、动作时间自供电选择：用户可根据负载电流要求对脱扣器进行设置调整；电子脱扣器由断路器自身提供能量，电流信号及脱扣器电
源来自安装于断路器内的环形电流互感器；
具有预报警指示：当负载电流超出预设定电流时，断路器面盖上的发光二极管指示为黄色：
具有过载指示：当负载电流超出整定电流时，断路器面盖上的发光二极管指示为红色；
具有消防专用的过载不脱扣只有报警功能：当负载电流过载运行时，断路器不脱扣，输出一个无源接点信号，驱动要相应的报警装置；
提供手持式专用检测器，以方便用户对断路器参数进行检测；
符合 GB/T14048.2 附录 F 的电磁兼容要求；
外形尺寸与 SYTM3 相同，安装具有互换性。
The SYTM3E series of intelligent molded case circuit breakers have a three-stage protection function. The circuit breaker of category B and
other short-circuit protection devices connected in the same circuit have a fully selective fit under short-circuit conditions:
It has three-stage protection action current and action time self-power supply selection: the user can adjust the setting of the trip unit
according to the load current requirement; the electronic trip unit provides energy from the circuit breaker itself, and the current signal and the
trip unit power supply are installed in the circuit breaker. a toroidal current transformer;
With pre-alarm indication: When the load current exceeds the preset current, the LED on the circuit breaker cover is yellow:
With overload indication: when the load current exceeds the setting current, the LED on the circuit breaker cover is indicated in red;
It has only the alarm function for fire-specific overload non-tripping: when the load current is overloaded, the circuit breaker does not trip,
outputs a passive contact signal, and drives the corresponding alarm device;
A hand-held dedicated detector is provided to facilitate user detection of circuit breaker parameters;
Meet the electromagnetic compatibility requirements of Appendix F of GB/T14048.2;
The dimensions are the same as SYTM3 and the installation is interchangeable.
