Terminal Blocks – Definition
Terminal blocks secure multiple wires to electrical switches or circuit systems. Terminal blocks are also called as terminal connectors or connection terminals. Being robust than any other connector, Terminal blocks have versatile usage in many industries across the world.
Terminal Blocks – Design
Terminal blocks composed of a conducting strip and a clamping component. Terminal blocks are modular in nature consisting of an insulated frame that secures wires and creates mounting for electrical projects.
Terminal blocks only have a single pole. Not all terminal blocks have contact pads or legs. The body of terminal blocks are usually made of insulating material such as plastic. With a tough safe design, terminal blocks have high current and voltage ratings.
The number of terminals in a terminal block can be adjusted.
Terminal Blocks - Types
The types of terminal blocks are as follows:
• Electrical Terminal Blocks
• Single/Dual/Three Level Terminal Blocks
• Ground Terminal Blocks, Fused Connection Terminal Blocks
• Thermocouple Terminal Blocks
• Sensor Blocks
• I/O Blocks
• Disconnect Terminal Blocks
• Power Distribution Blocks
Terminal Block Mechanism
The mechanism of terminal blocks depends on its features, orientation, contact specs, mounting and terminal type.
DIN Rail Mounted Terminal Blocks
The rail specification of terminal blocks was established by Deutsches Institut fur Normung (DIN) - a German body. Usually terminal blocks are mounted on DIN rails. DIN rails of terminal blocks are further categorized into three – G section, C section and top hat.
