Current Monitoring Relay, Over/ Under Current, 1A/2A/5A/8A/16A, AC/DC24V-240V

The current monitoring relay is a protection device in the power system, which can monitor the current in the circuit in real-time, such as monitoring the heating conditions in the track switch, heating cables, and the consumption of single-phase motors, to prevent circuit overload, short circuit, and other faults from causing equipment damage or fire and other safety accidents. It is compact, only 18mm wide, and easy to install on the 35mm rail.

Feature

• Adjustable delay 0.1-10 s to eliminate short current peaks, to avoid starting current of motor loads.
• Flexible adjustment by potentiometer, choice of 6 ranges: AC 0.05-0.5A; AC 0.1-1A; AC 0.2-2A; AC 0.5-5A; AC 0.8-8A; AC 1.6-16A-Power up delay.
• Possible to use it for current scanning from the current transformer.
• Universal supply AC/DC 24V-240V.
• Relay status is indicated by LED.
• 1-MoDULE, DIN rail mounting.

Tips: How to choose a suitable current monitoring relay?

The first is the electrical parameters, including rated voltage, rated current, action time release time, etc. These parameters must meet the needs of the actual application scenario. It is best to be able to combine the working environment, and environmental factors such as temperature, humidity, vibration, etc. must be considered to select the size that meets the installation space requirements.

The second is the relay type, which requires selecting the appropriate relay type and function according to the load type and control requirements, such as AC relay, DC relay, solid-state relay, etc. In addition, some additional functions cannot be ignored. Some relays may have additional functions, such as fault indication, remote control, communication interface, etc.
