RXMK1 Type Large Capacity AC Intermediate RelayDetailed product description：

Application of RXMK1 high-capacity AC intermediate relay
Used in industrial automation control and secondary circuits of power systems as an intermediate auxiliary to expand the control range.

2 Characteristics
2.1 Small size, large contact breaking capacity.
2.2 The coil is excited by alternating current.

3 Principles of Action
The RXMKl high-capacity intermediate relay is an electromagnetic relay. It consists of three parts: electromagnetic system, contact system, and short-circuit ring. The electromagnetic system adopts a direct acting structure with a large working stroke. The contact system adopts bridge contacts with large breaking capacity. When the coil is energized, it generates a magnetic field that attracts the iron core. The contact conversion is driven by the iron core. The shell adopts the imported Combiflex protruding modular insertion structure.

Technical data of RXMK1 high-capacity AC intermediate relay
4.1 Operating voltage:<80% of rated voltage.
4.2 Return voltage:>15% of rated voltage.
4.3 Action time: ≤ 20ms.
4.4 Coil power consumption: 6VA.
4.5 Contact breaking capacity: When AC: V ≯ 250V, I ≯ 10A (power factor of 0.4), the capacity is 1000VA.
When DC: V ≯ 250V, I ≯ 5A (L/R=40ms), the capacity is 100W.
To increase the contact breaking capacity, connect the contacts in series according to the data in Table 1.

When the voltage (DC) is 55V	20A/20A (single contact)/(double contact series)
When the voltage (DC) is 110V	5A/20A (single contact)/(double contact series)
When the voltage (DC) is 125V	4A/20A (single contact)/(double contact series)
When the voltage (DC) is 220V	1A/6A (single contact)/(double contact series)
When the voltage (DC) is 250V	0.8A/4A (single contact)/(double contact series)

4.6 Insulation withstand voltage: 50Hz, 1min, 2kV.
4.7 Impulse voltage: 5kV.
4.8 Can withstand seismic waves with a moderate magnitude of 5-15Hz.
