RH4B-ULCAC120V

Power Relays, over 2 Amps, are devices that can provide specialized switching of heavy current and provide isolation between different circuits depending on application. The RH4B-ULCAC120V is one such type of Power Relay, and it is commonly used in many different types of commercial, residential, and industrial applications. The RH4B-ULCAC120V is capable of switching loads up to 120V and 3A. It is able to handle extremely heavy current switching needs and is commonly used for applications such as lighting control, HVAC control, motor starters, and limit switches.

The RH4B-ULCAC120V has two independent coil systems. One coil is used to switch the target load when it is energized and the other coil is used to de-energize the same target load. It has a single-pole, double-throw (SPDT) construction where the common and normally-open contacts are separate, making it suitable for momentary and latching type applications. The contact and coil construction are usually made of copper for better durability. The RH4B-ULCAC120V also has multiple safety features like surge protection, short circuit protection, and overload protection.

One of the key features of the RH4B-ULCAC120V is its ability to act as an isolator for two separate circuits. This is done by using its normally-open and normally-closed contacts. When the relay is energized, the normally-open contact is connected to the normally-closed contact, allowing the current to flow from one circuit to the other. This is useful for applications where one needs to isolate one circuit from another, such as when a signal needs to be sent from one system to another, or when a switch needs to be actuated to control a certain function.

Another feature of the RH4B-ULCAC120V is its ability to act as a switch. This is done by using the normally-open and normally-closed contacts. When the relay is energized, the normally-open contact connects to the normally-closed contact, and the current is allowed to flow from the one circuit to the other. The current is then used to switch a particular application or function, such as turning on a motor or a light.

The RH4B-ULCAC120V is also capable of controlling larger currents than a normal switch. This is accomplished by utilizing the relay’s two independent coils and the combination of its normally-open and normally-closed contacts. By using both coils, the relay is able to control more current than a switch would. It also has the ability to control the current more accurately and efficiently.

The RH4B-ULCAC120V is a type of Power Relay that is commonly used in many applications. It is able to handle extremely heavy current switching needs and is capable of controlling larger currents than a normal switch. It has a single-pole, double-throw (SPDT) construction and is able to provide safety features such as surge protection, short circuit protection, and overload protection. It also has the ability to act as an isolator for two separate circuits, as well as act as a switch. Overall, the RH4B-ULCAC120V is a great Power Relay for many commercial, residential, and industrial applications.
