What are the Different Types Of Din Rail Terminal Block And Their Working

 Type, construction, Appl., Range 

Terminal Blocks are used to systematically connect two or more wires inside an electrical panel or Junction Box, allowing you to create complex circuits as per your wiring requirements and offers you easy traceability of these circuits. Terminal Blocks are mostly DIN Rail Mounting and are made up of Polyamide; there are different types of Terminal Blocks as per connection technology such as Screw Clamp, Spring Clamp, Push-In Type, and Stud Type Terminal Blocks. These Terminal Blocks can be further classified depending upon their functionalities such as Standard Feed Through Terminals, Multiple Connection Terminals, Multiple Level Terminals,

Fuse Protection Terminals, Disconnect & Test type Terminals, Ground and Shield Terminals, and Distribution Blocks.

• Screw Clamp Type Terminal Blocks – These are the most commonly used Electrical Terminal Blocks with screw and clamp arrangement, a high Torque clamping system on the Screw Clamp terminals ensures safe gas-tight connections. This connection technology is most commonly used and offers a wide wire clamping range from 2.5 sq. mm to 120 sq. mm. 

• Spring Clamp Type Terminal Blocks – Spring Terminal Blocks have a highly reliable Spring Clamp connection system. The spring clamp actuated using a standard screwdriver and connection is completed by simply inserting the prepared wire in the clamping point and removing the screwdriver. These pre-stressed clamps secure your connections against heavy vibrations. Spring Clamp Terminal Blocks widely used in applications like Lift, Elevators, Cranes Machine Building, and Rolling stocks which are subject to shock and vibrations. 

• Push-In Type Terminal Blocks – Push-In Terminal Blocks have a specialized connection system that enables tool-less wire connection. Reliable vibration resistant, Gas tight connections are made within built high-quality stainless steel Push-In spring clamps. Solid wires and crimped Lugs wires can be directly pressed against the clamps, and your wiring is done. If bare wires / Flexible wires are used for wiring the push button provided on the top, they need to press with a screwdriver's help, which will actuate the Push-In clamp, allowing you to insert the wire in the connection point. This connection method is extremely fast to offer quick connections saving your wiring time.

• Stud Type Terminal Blocks – Stud Terminals are also known as Bolt type Terminal Blocks or Barrier Type Terminal Blocks. They are used in an application subject to severe vibration. The connection made by crimping the wire on a Ring/fork lug is screwed on the flat current bar. These terminals are often used for power connections as bigger cross-section wires can be easily connected to Nut and Bolts wiring arrangement offered by these Terminal Blocks.
