Main categories of circuit breakers

According to the number of poles: single pole, two poles, three poles and four poles; according to the installation method: plug-in type, fixed type and drawer type. Product introduction A9/EC65 small circuit breaker: lighting distribution circuit, short circuit and overload protection. A9LE/EPNLE leakage circuit breaker: short circuit overload and leakage protection in the grounding system. The normal operation fault protection of the circuit breaker makes the phase line and the neutral line in the disconnected state when the circuit breaker is in the disconnected position to avoid the neutral line being energized when the fault occurs. When performing the connection and disconnection operations, the neutral line is connected first and disconnected later. 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] Over-undervoltage release: The fully automatic over-undervoltage delay protector is a new generation of products developed according to market needs. The protector is reasonably designed and assembled with imported components and domestic brand components. The product can quickly and reliably switch the power supply under high voltage impact and undervoltage conditions to protect household appliances. When the voltage returns to normal, it can automatically connect the circuit and restore power supply after a delay, which can effectively protect the electrical appliances from the impact of instantaneous power supply. All functions are fully automated, no special operation is required, and two-color light-emitting diodes are used for indication, which is safe and fast.
EC100 miniature circuit breaker: industrial power distribution system, short circuit and overload protection. Rated current 63A-125A, high rated short-circuit breaking capacity, with short-circuit current limiting structure. Complete protection functions, with overload and short-circuit protection devices, safe and reliable wiring, "frame-type" wiring structure, simple function expansion, safe and reliable. Can be equipped with a variety of accessories: leakage release, auxiliary contact, alarm contact, shunt release, undervoltage release, busbar.
EPD surge protector: EPD plug-in type adopts the same working principle and selection criteria as fixed surge protection. Protects 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 long-distance connection and disconnection of circuits, and can be combined with thermal relays or electronic protectors of corresponding specifications to form electromagnetic or mechatronic motor starters.
ENS molded case circuit breaker: The plastic case circuit breaker is one of the new circuit breakers designed and developed with comprehensive international advanced technology. It is used to divide the rated insulation voltage of the circuit breaker to 800V, suitable for AC 50Hz and 60Hz, rated working voltage up to 690V, and rated working current from 6A to 1250A in the distribution network circuit. It is used to distribute electrical energy and protect the line and power supply equipment from damage caused by overload, short circuit, undervoltage and other faults. It can also be used as an infrequent start-up and overload, short circuit and undervoltage protection for motors. The circuit breaker has the characteristics of small size, high breaking, short arcing (or no arcing), and is an ideal product for users. The circuit breaker can be installed vertically (i.e. vertically) or horizontally (horizontally).
ENSLE molded case leakage circuit breaker: used to provide indirect contact protection for people, and can also prevent fire hazards caused by ground fault current due to insulation damage of equipment, and can be used to distribute electric energy and protect the overload short circuit of lines and power equipment. It can also be used for infrequent line conversion and infrequent motor starting. The working power sampling of the leakage protection module of the conventional residual current protection circuit breaker is two-phase, and this series of circuit breakers is three-phase. If any phase is missing, the leakage protection module of the circuit breaker can still work normally. The rated residual operating current and the maximum disconnection time can be adjusted on site according to the actual situation.
EGL-125 isolating switch: The isolating switch is the most commonly used electrical appliance in high-voltage switch electrical appliances, and it plays an isolating 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 great 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 the circuit without load current. EGL-125-4000A is suitable for switching two low-voltage circuits or switching or safe isolation of two load devices.
EATS3 dual power transfer switch: two power supplies are used to ensure the reliability of power supply, and one product can reliably switch between the two power supplies. This product has two switching functions: automatic switching and automatic recovery, and automatic switching without automatic recovery. This is a manual transfer switch. The design is novel, safe and reliable, with a high degree of automation and a wide range of applications.
EW45 universal intelligent circuit breaker: mainly used to distribute electrical energy and protect lines and power equipment from overload, short circuit, undervoltage, single-phase grounding and other faults. The circuit breaker has a variety of intelligent protection functions, can be used for selective protection, and has precise action to avoid unnecessary power outages and improve power supply reliability and safety.
