The single-phase current monitoring relay equipped with LED lights, quickly understands the working status of the equipment. It can be used through overdrive/flow monitor mode, which is equipped to handle a wide input voltage range, accepting AC/DC 12-240V inputs. The current monitoring relay has fast operation speed, high accuracy, good maneuverability, and a current range of 2-20A, which have led to its widespread use in power systems, such as rail switches, heating cables, and consumption of one-phase motors, indicating current flow.

Feature

Through center design, no need to disconnect the current circuit, throughcenter installation is convenient to use.
Cover/Under current monitoring mode can be set by knob.
With AC and DC universal testing specifications optional.
An isolation current transformer is adopted, and external current transformers can be connected to expand the monitoring current range.
2 C/O output.
Universal supply AC/DC 24-240 V.
Relay status is indicated by LED.
1-MODULE, DIN rail mounting.

Tips: The working principle of a single-phase current monitoring relay

The working principle of a 1-phase current monitoring relay and the principles of electromagnetics and electromagnetic sensing. When an electric current occurs in this line, a constant electromagnetic wave is generated, producing an electric current. This sensitive electric current influences the magnetic field in the sphere and then influences the state of the contact point. Through the parameters of the rational design, precise control of the current control device can be realized. For example, by changing the number of circles, material, length, etc.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
