Product introduction A9/EC65 miniature circuit breaker: lighting distribution circuit, short circuit and overload protection.
A9LE/EPNLE leakage circuit breaker: short circuit overload and leakage protection in grounding systems. The normal operation fault protection of the circuit breaker keeps the phase line and neutral line in the disconnected state when the circuit breaker is in the breaking position to avoid being charged when the neutral line fails. When making and breaking operations, the neutral line has priority in making and breaking with lag. It has short-circuit current limiting function and high rated short-circuit breaking capacity. It has overload protection, short circuit leakage and voltage protection devices, complete protection functions, and convenient and reliable wiring. [2]
Overvoltage and undervoltage release: The fully automatic overvoltage and undervoltage time delay protector is a new generation product developed according to market needs. The protector is reasonably designed and assembled with imported components and domestic famous-brand components. The product can quickly and reliably switch power supply and protect household appliances under high-voltage impact and under-voltage conditions. When the voltage returns to the normal value, the circuit can be automatically connected and the power supply restored after a delay, which can effectively protect the electrical appliances from the impact of instantaneous power-on. All functions are fully automated, no need for special personnel to operate, and dual-color LED indicators are used, which is safe and fast.
EC100 miniature circuit breaker: industrial power distribution system, short circuit and overload protection. The rated current is 63A-125A, the rated short-circuit breaking capacity is high, and it has a short-circuit current limiting structure. It has complete protection functions, has overload and short-circuit protection devices, and the wiring is safe and reliable. It adopts a "frame" wiring structure, and the function expansion is simple, safe and reliable. Can be equipped with a variety of accessories: leakage release, auxiliary contacts, alarm contacts, shunt release, undervoltage release, bus bar.
EPD surge protector: EPD plug-in type uses the same working principle and selection criteria as fixed surge protection. Protection against indirect lightning and direct lightning effects or other transient overvoltage surges.
EIC1 AC contactor: mainly used for AC 50Hz or 60Hz rated voltage up to 660V and below, for connecting and breaking circuits over long distances, and can be combined with thermal relays or electronic protectors of corresponding specifications to form electromagnetic or electromechanical integration of motor starter.
ENS plastic case circuit breaker: Plastic case circuit breaker is one of the new circuit breakers designed and developed using international advanced technology. The circuit breaker is used to divide the rated insulation voltage of 800V, suitable for AC 50Hz and 60Hz, rated operating voltage to 690V, rated operating current from 6A to 1250A in distribution network circuits, used to distribute electric energy and protect lines and power equipment from It can prevent damage from overload, short circuit, under voltage and other faults, and can also be used as infrequent starting and overload, short circuit and under voltage protection of the motor. This circuit breaker has the characteristics of small size, high breaking capacity, short arcing (or no arcing), etc., making it an ideal product for users. The circuit breaker can be installed vertically (that is, vertical installation) or horizontally (horizontally installed).
ENSLE plastic case leakage circuit breaker: It is used to provide indirect contact protection for people. It can also prevent fire hazards caused by equipment insulation damage and ground fault current. It can also be used to distribute electric energy and protect wires and power supply equipment from overload short circuits. It can be used for infrequent switching of lines and infrequent starting of motors. The working power supply of the conventional leakage protection module with residual current protection circuit breaker is two-phase. This series of circuit breakers is three-phase. If any phase is missing, the circuit breaker The leakage protection module can still work normally, and the rated residual operating current and maximum disconnection time can be adjusted on site according to the actual situation.
EGL-125 isolation switch: The isolation switch is the most commonly used electrical appliance among high-voltage switching appliances. It plays an isolation role in the circuit. Its working principle and structure are relatively simple, but due to its large usage and high working reliability requirements, it has a greater impact on the design, establishment and safe operation of substations and power plants. The main feature of the knife switch is that it has no arc extinguishing ability and can only open and close circuits when there is no load current. EGL-125-4000A is suitable for switching two low-voltage circuits or switching or safety isolation of two load devices.
EATS3 dual power transfer switch: uses two power supplies to ensure the reliability of power supply. One product can reliably switch between the two power supplies. This product has two switching functions: automatic switching and self-recovery and automatic switching and non-self-recovery. This model is a manual transfer switch. Novel design, safe and reliable, high degree of automation and wide range of use.
EW45 universal intelligent circuit breaker: It is mainly used to distribute electric energy and protect lines and power equipment from overload, short circuit, undervoltage, single-phase grounding and other faults. This circuit breaker has a variety of intelligent protection functions and can be used for selective protection. , and the action is precise to avoid unnecessary power outages and improve the reliability and safety of power supply.
