主要用来保护住宅及其他类似建筑物的电气线路设备，亦作为线路的不频繁转换之用。而内部则采用的是双极结构设计，其中一极有保护 ( 过
载，短路 ) 一极无保护。双极同时闭合，同时断开，达到零、火同时闭合同时断开的效果，从而使居民住宅用电真正做到安全可靠，万无一失，
节省造价。
该产品符合 IEC60898、GB10963.1 标准。
SNDDPN-32 miniature circuit breaker is applicable to 50Hz frequency, 230V rated voltage and 6A ~ 32A rated current. It is a current
limiting miniature circuit breaker with double protection of overload and short circuit. It is mainly used to protect the electrical line
equipment of residential and other similar buildings, and also used for non frequent line conversion. The interior adopts a bipolar
structure design, in which one pole has protection (overload, short circuit) and the other pole has no protection. The two poles are
closed and disconnected at the same time, so as to achieve the effect of zero and fire closing at the same time and disconnection at
the same time, so as to make the residential electricity really safe and reliable, foolproof and save the cost.
The product complies with IEC60898、GB10963.1 standards.

SNDDPNLE-32 漏电断路器适用于频率 50HZ，额定电压 230V，额定电流从 6A 至 32A 的电路中，作为触电保护和设备漏电保护之用，并
且有过载，短路保护功能，也可以在正常情况下作为线路的不频繁转换之用。漏电断路器主要由绝子绝缘外壳，操作机构，动、静触头、
延时、瞬时脱扣器、灭孤室、电子放大线路、零序互感器、漏电脱扣器等组成。将漏电断路器手柄扳向 ON 位置时，通过机械机构带动动
触头向静解可靠接触，接通电路。当线路发生过载故障时，过载电流使热双金属元件弯曲并推动锁扣器动作，使得机械锁定机构复位，动
触头迅速离开静触头，从而实现分断线路的功能；当线路发生短路故障时，短路电流使瞬时脱扣器动作，铁芯顶杆推动锁扣使锁定机械复
位，实现分断功能；当线路发生漏电或触电故障时，零序电流互感器输出的信号触发可控硅导通，漏电脱扣铁芯动作，推断路器脱扣，使
漏电断路器在 0.1s 内切断电源，从而实现漏电保护功能。
本产品符合标准 GB16917.1、IEC1009.1
SNDDPNLE-32 leakage circuit breaker is applicable to the circuit with frequency of 50Hz, rated voltage of 230V and rated current
from 6a to 32A. It is used for electric shock protection and equipment leakage protection. It also has overload and short-circuit
protection functions. It can also be used for infrequent line conversion under normal conditions. The leakage circuit breaker is
mainly composed of insulator insulation shell, operating mechanism, dynamic and static contacts, time delay, instantaneous
release, isolation chamber, electronic amplification circuit, zero sequence transformer, leakage release, etc. When the handle of
the leakage circuit breaker is turned to the on position, the moving contact is driven to the static release reliable contact through
the mechanical mechanism to connect the circuit. In case of overload fault of the line, the overload current bends the thermal
bimetallic element and pushes the latch to act, so as to reset the mechanical locking mechanism, and the moving contact quickly
leaves the static contact, so as to realize the function of breaking the line; When a short-circuit fault occurs in the line, the shortcircuit current causes the instantaneous release to act, and the iron core top rod pushes the latch to reset the locking mechanism
to realize the breaking function; In case of leakage or electric shock fault of the line, the signal output by the zero sequence current
transformer triggers the thyristor to turn on, the leakage trip iron core acts, infers that the circuit breaker trips, so as to cut off the
power supply within 0.1s, so as to realize the leakage protection function.
This product complies with GB16917.1 and IEC1009.1

将剩余电流动作断路器手柄扳向 ON 位置时，通过机械机构带动触头向静触头动动并与静触头可靠接触，接通电路。当线路发生过
载故障时，过载电流使热双金属元件弯曲并推动杠杆使得机械锁定机构复位，动触头迅速离开静触头，从而实现分断线路的功能；当线路
发生短路故障时，短路电流使瞬时脱扣器动作，铁心顶杆推动杠杆得锁定机械复位，实现分断功能。当线路发生剩余电流或触电故障时，
零序互感器输出的信号触发可控硅导通，使剩余电流脱扣器铁心动作，推杆推动断路器脱扣，使剩余电流动作断路器在极短时间内切断电
流，从而实现剩余电流保护功能。断路器可装配 OF、SD、MX+OF、MN。
When the handle of the residual current operated circuit breaker is turned to the on position, the contact is driven to move to
the static contact through the mechanical mechanism and reliably contact with the static contact to connect the circuit. In case of
overload fault of the line, the overload current bends the thermal bimetallic element and pushes the lever to reset the mechanical
locking mechanism, and the moving contact quickly leaves the static contact, so as to realize the function of breaking the line;
When a short-circuit fault occurs in the line, the short-circuit current causes the instantaneous release to act, and the iron core push
rod pushes the locking mechanical reset of the lever to realize the breaking function. When the residual current or electric shock
fault occurs in the line, the signal output by the zero sequence transformer triggers the thyristor to turn on, so that the iron core
of the residual current release acts, and the push rod pushes the circuit breaker to trip, so that the residual current action circuit
breaker cuts off the current in a very short time, so as to realize the residual current protection function. The circuit breaker can be
equipped with OF、SD、MX+OF、MN.

SNDSK47-125 隔离开关具有较高的动热稳定性，主要作为终端组合电器中的总开关，适用于交流 50Hz 或 60Hz，额定电压 400V 及以下
的配电和控制回路中，也可用于控制电动机，小功率电器的照明，广泛应用于工矿企业，高层建筑，商业及家庭等场所。隔离开关由外壳，
操作机构、触头系统构成。操作机构与触头系统为钢性连接，触头系统采用双断点直动结构，手柄操作机构用弹簧储能实现快速通断，克
服了人力操作速度快慢的影响，提高了工作的可靠性，触头开闭状态有明确的触头位置指示，分别用“ON”( 红色 ) 表示触头闭合位置、
“OFF”( 绿色 ) 表示触头断开位置，可防止误操作，提高了安全性。
该产品符合 GB14048.3 标准。
SNDSK47-125 disconnector has high dynamic and thermal stability. It is mainly used as the main switch in terminal combined
electrical appliances. It is suitable for power distribution and control circuits with AC 50Hz or 60Hz and rated voltage of 400V and
below. It can also be used to control the lighting of motors and low-power electrical appliances. It is widely used in industrial and
mining enterprises, high-rise buildings, commerce, families and other places. The disconnector is composed of shell, operating
mechanism and contact system. The operating mechanism is rigidly connected with the contact system. The contact system adopts
a double breakpoint direct action structure. The handle operating mechanism uses spring energy storage to realize rapid on-off,
which overcomes the influence of the speed of manual operation and improves the reliability of work. The contact opening and
closing state has clear contact position indication, and the contact closing position is indicated by \"on\" (red) and \"off\" (green)
respectively Indicates the disconnected position of the contact, which can prevent misoperation and improve safety.
The product complies with GB14048.3 standard.

SNDQG 自复式过欠压保护器适用于单相交流电压 220V, 频率 50Hz, 额定工作电流 60A 及以下的用户或负载。作为由中性线故障引起的单
相线路过欠电压对单相用电设备的保护。当供电线路出现过电压、欠电压时，保护器能在持续高压冲击下迅速、安全地切断电路，避免异
常电压送入终端电器造成事故的发生，当电压恢复正常值，保护器将在规定时间内自动接通电路，确保终端电器在无人值守情况下正常运
行。面板上的双色发光二极管能指示保护器工作状况，指示灯发绿光时正常供电，发红光时保护功能启动切断供电。主要用于家庭及商场
配电 ( 单相 AC230V, 三相四线 AC415V) 线路中作为过电压、欠电压、断相、断零线保护用。
SNDQG self resetting overvoltage and undervoltage protector is applicable to users or loads with single-phase AC voltage of 220V,
frequency of 50Hz and rated working current of 60A and below. As the protection of single-phase electrical equipment from singlephase line overvoltage and undervoltage caused by neutral line fault. In case of overvoltage and undervoltage in the power supply
line, the protector can quickly and safely cut off the circuit under the continuous high-voltage impact to avoid accidents caused
by abnormal voltage sent to the terminal electrical appliances. When the voltage returns to the normal value, the protector will
automatically connect the circuit within the specified time to ensure the normal operation of the terminal electrical appliances
under unattended conditions. The two-color LED on the panel can indicate the working condition of the protector. When the
indicator light emits green light, the power supply is normal. When the indicator light emits red light, the protection function is
started to cut off the power supply. It is mainly used for overvoltage, undervoltage, phase failure and zero line failure protection in
household and mall power distribution (single-phase AC230V, three-phase four wire ac415V).
