Power Relays, Over 2 Amps

RM703730 is a power relay designed for heavy-duty applications with currents over 2 amps. It is purpose built to deliver reliable switching, with low power consumption and long life. This makes it ideal for use in a variety of industrial, energy and transport applications.

Application Field

RM703730 is suitable for a wide range of power relay applications, such as motor control, industrial process control, switching power supplies, lighting systems, HVAC systems, electrical engineering and material handling equipment. Its design allows for a variety of configuration options, making it an adaptable component to suit diverse and specific applications. The SPDT design can also be used with open or enclosed contact configurations, as well as dry or wet-duty contacts.

Working Principle

The RM703730 power relay works by energizing a coil which magnetically attracts the armature, to close the contacts and complete an electrical circuit. It is designed to be able to switch higher currents without the issue of arcing and is engineered for vibration resistance. The relay is designed with a high voltage/current rating, meaning that it can take the strain of frequent use and long life reliability.

The RM703730 has a built-in, adjustable hysteresis circuit, which helps to ensure that the contacts switch reliably and ensures that the contacts stay in their required positions. The adjustable hysteresis feature allows the switching trigger points to be adjusted to suit different switching criteria, making the RM703730 especially suitable for adjustable control applications.

The power relay has a coil current rating of 1.45A, with a switching capacity of 220V AC/DC, and a voltage rating of up to 440V AC. The RM703730 is fitted with anti-corrosion treatments, glass-filled resin protection, and an underside mounted diode for protection from electrical surges.

Conclusion

RM703730 is designed for heavy-duty applications with currents over 2 amps and is suitable for a wide range of power relay applications. It has a high voltage/current rating, adjustable hysteresis, anti-corrosion treatments, glass-filled resin protection, and an underside mounted diode for protection from electrical surges. These features make the RM703730 a reliable and adaptable choice for a wide variety of applications.
