Siemens motor protection circuit breakers are classified by pole number: single pole, two pole, three pole, and four pole, etc;

According to the installation method, there are plug-in, fixed, and drawer types.

Product Introduction A9/EC65Siemens molded case circuit breakerLighting distribution circuit, short circuit and overload protection.

A9LE/EPNLE residual current circuit breaker: In the grounding system, it provides short-circuit overload and residual current protection. The normal operation fault protection of the circuit breaker ensures that both the phase line and neutral line are in the disconnected state when the circuit breaker is in the disconnected position, to prevent the neutral line from being energized in case of a fault. When performing connection and disconnection operations, the neutral wire connection takes priority and disconnection lags behind. It has short-circuit current limiting function and high rated short-circuit breaking capacity. Equipped with overload protection, short-circuit leakage and voltage protection devices, with complete protection functions and convenient and reliable wiring.

Overvoltage and undervoltage release: The fully automatic overvoltage and undervoltage delay protector is a new generation product developed by our company according to market demand. The protector is designed reasonably and assembled with imported components and domestic branded components. The product can quickly and reliably switch power under high voltage impact and undervoltage conditions, protecting household appliances. When the voltage returns to normal, it can automatically connect the circuit and restore power supply after a delay, effectively protecting electrical appliances from the impact of momentary power on. All functions are fully automated, without the need for dedicated personnel to operate. Dual color light-emitting diodes are used for indication, ensuring safety and speed.

EC100 miniature circuit breaker: industrial distribution system, short circuit and overload protection. Rated current 63A-125A, high rated short-circuit breaking capacity, with short-circuit current limiting structure. The protection function is complete, with overload and short circuit protection devices, and the wiring is safe and reliable. It adopts a 'frame' wiring structure, which is easy to expand and safe and reliable. Multiple accessories are available: leakage release, auxiliary contact, alarm contact, shunt release, undervoltage release, busbar.

EPD surge protector: The EPD plug-in type adopts the same working principle and selection criteria as the fixed type surge protector. Protect against surges caused by indirect lightning, direct lightning, or other transient overvoltages.

The main electrical properties of electrical performance connectors include contact resistance, insulation resistance, and electrical strength.

① High quality electrical connectors with high contact resistance should have low and stable contact resistance. The contact resistance of connectors varies from a few milliohms to tens of milliohms.

② The insulation resistance is an indicator that measures the insulation performance between the contact parts of an electrical connector and between the contact parts and the housing. Its magnitude ranges from several hundred megaohms to several hundred gigaohms.

③ Electrical strength, also known as withstand voltage or dielectric withstand voltage, is the ability to withstand the rated test voltage between connector contacts or between contacts and the housing.

④ Other electrical properties. Electromagnetic interference leakage attenuation is used to evaluate the electromagnetic interference shielding effect of connectors, and electromagnetic interference leakage attenuation is used to evaluate the electromagnetic interference shielding effect of connectors. It is generally tested in the frequency range of 100MHz~10GHz. For RF coaxial connectors, there are also electrical indicators such as characteristic impedance, insertion loss, reflection coefficient, and voltage standing wave ratio (VSWR). Due to the development of digital technology, a new type of connector called high-speed signal connector has emerged to connect and transmit high-speed digital pulse signals. Correspondingly, in terms of electrical performance, in addition to characteristic impedance, some new electrical indicators have also emerged, such as crosstalk, transmission delay, skew, etc.
