GRT508B 100A GENERAL PURPOSE SINGLE PHASE LATCHING RELAY
- Description
-
Single-phase 100A Latching Relay is a power control device with a power-off memory function. It is suitable for applications that require high-current load control and frequent power outages while maintaining the last switch state. The product adopts a magnetic holding structure design, which completes the pull-in or release action at the moment of power-on. The control end does not need a continuous power supply, thereby effectively reducing system energy consumption and improving equipment operation efficiency. It has built-in high-performance magnetic steel and high-conductivity copper contacts to ensure long-term stable operation under 100A rated current conditions, and has excellent arc resistance and overload resistance.
The product shell is injection molded with flame-retardant materials, has good insulation performance and mechanical strength, and meets the use requirements in complex environments. It has a compact structure and flexible installation methods. It supports rail installation or panel fixing, which is easy to integrate into various terminal devices such as smart meters, load control terminals, and power management systems. At the same time, it has strong anti-electromagnetic interference ability and accurate contact action, which avoids the problem of false operation of traditional relays due to instantaneous voltage fluctuations, and improves the reliability and safety of the system.
In addition, the relay has simple control logic, supports multiple voltage control signal inputs, and has strong adaptability. It is one of the important components in the current intelligent power distribution and energy consumption management field. Its non-polarity control terminal design reduces the complexity of wiring, making engineering wiring more efficient and faster. Whether in residential, commercial, or industrial power distribution systems, the Single-phase 100A Latching Relay can achieve safe, energy-saving, and intelligent load control solutions, providing users with a more stable and reliable power control experience.
