Terminal Blocks - Barrier Blocks

The 431303-03-0 is a barrier block model of terminal blocks manufactured by Phoenix Contact, a German electronic component manufacturer. It is a three pole barrier block that is typically used in the termination of wires for electrical systems such as junction boxes of distribution panels, meaning that the individual electrical circuits can be disconnected without affecting the whole system. It is also useful in medical, chemical, hazardous area and food industry applications.

The 431303-03-0 is a two-piece terminal block system, consisting of a base and a plug-in unit. The base has a pin system which is spaced to make contact with the receiver on the plug-in unit. The base of the 431303-03-0 can be mounted onto a DIN-rail or the control panel. It is also easy to mount because of its locking screws and plastic hook closures.

The plug-in unit of the 431303-03-0 is insulated with a high-temperature plastic and has three poles for an uninterrupted connection. It is connected directly to the base and has contact bars to ensure that the interruption of the wires is perfectly safe. Furthermore, the plug-in unit also has an LED indicator for active circuits and a visible bridge that runs along the length of the plug-in unit.

The barrier blocks are a very convenient means of wiring as the connection can be easily removed and reattached. They are easy to install and don’t require much time or effort during installation. Furthermore, they are also well-suited for applications that require high security or in hazardous environments as they can protect electrical circuits from shocks, overheating and fire.

The barrier blocks also require less space to install as the entire unit is the size of a few wires, thus occupying little space. The installation can also be carried out in an enclosed area because the insulation of the plug-in unit protects against electric shocks or sparks. In addition, the bridge running along the length of the plug-in unit is also a very useful feature as it helps to visually identify the various connections and ensures that everything is in order.

The 431303-03-0 is a great option for wiring applications in residential and commercial applications as it is easy to install and requires minimal maintenance. It has a range of current and voltage ranges and is available in a variety of sizes. It is also an ideal solution for applications that require high security or in areas with hazardous conditions.
