Terminal junction systems are devices used to terminate opposite ends of a communications cable. The SJS420700 is a reliable and affordable terminal junction system, used for both electrical and telecommunications applications. This terminal junction system had been designed for ease-of-use and installation for medium-voltage and low-voltage branch circuits.

Features and Benefits

The SJS420700 adoption of an all-in-one design makes it easier for engineers and technicians to use in a variety of applications. It can be mounted easily without needing extra components. Its compact size makes it an ideal choice for tight installation locations. The insulated input and output contacts allow for high levels of electrical security and isolation, making it important to prevent unintended contact with energized conductors. The SJS420700 also features a ground connection with a large contact pad to ensure proper and secure resistive grounding.

Application Field

The SJS420700 offers several electrical applications. For electrical applications, the SJS420700 is suitable for systems over 120V up to 600V, and offers a wide range of protection such as overload protection, overvoltage protection and short-circuit protection. It can be used as a simple way to bring power from a main source to sub-load locations, as well as for the termination of solar power systems. Additionally, the SJS420700 can be used to terminate branch circuits with industrial machinery, utility equipment and other applications requiring specialized power.

Working Principle

The SJS420700 terminal junction system has two inputs as well as two output terminals. The input terminals are used to connect the source power and the output terminals are used to connect the load, all of which are climate controlled. The junction system operates similarly to a basic electrical switch, with a thermostat controlling two separate relays. When the overcurrent reaches a certain level, the relays open, and when the overcurrent decreases, the relays close. This protects and isolates the load from the source and vice versa. When either of the relays are open, the circuit is broken and the SJS420700 prevents the current from passing.

The SJS420700 is a great choice for a variety of applications, not limited to all-in-one designs. The implementation of dual contacts, resistive grounding and additional protection make it safer and more reliable for almost any application.
