Specialty Terminal Blocks
Component terminal blocks work with other individual components, making them the most customizable terminal blocks. Device terminal blocks are feed-through terminal blocks designed for use in potentially explosive areas. Disconnect terminal blocks are designed for applications where each circuit needs individual protection. Distribution terminal blocks connect in a number of different positions, mounting options and colors with up to 18 terminal points. High current terminal blocks are rated up to 1500 V and can receive large conductors. Installation terminal blocks have a low-profile design for flat installation distributors. Miniature terminal blocks are designed for space-limited control cabinets. There are horizontal connections for flat cabinets and vertical connections for limited space. Multi-conductor terminal blocks can connect up to four conductors with individual wiring at each terminal point. Panel feed-through terminal blocks route high currents permanently through panels. Potential collective terminal blocks are a hybrid terminal block with two different connection types. Thermoelectric terminal blocks are used to extend thermocouple equalizing conductors in corresponding measuring circuits. Fuse terminal blocks add a layer of protection with easy to access fuse inserts.

Single Level Pass Through Terminal Blocks are used to connect two wires together with a common junction point. This is helpful when a component needs to be disconnected or isolated within a circuit. These are the most common types of terminal blocks in industrial applications.
Ground Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: they are grounded. These terminal blocks have a metal connection from where the wire is terminated, all the way to the bottom of the block where it will clamp into the panel. This allows for an electrical circuit to be grounded without running a wire to the main ground connection on a breaker or surge protector.
Fused Terminal Blocks function almost exactly like most pass through terminal blocks with one exception: the presence of a fuse. This fuse provides protection for components from too much voltage or current.
Multilevel Terminal Blocks are used to connect two wires together with a common junction point, just like single pass though terminal blocks, but with the advantage of making two electrical connections in the same block. These blocks also incorporate fuses and can be grounded.
Disconnect Terminal Blocks are similar to fused blocks, however the disconnect stops the flow of electricity by lifting a lever on the terminal block. Unlike fuse blocks, they are a more permanent solution, but will not provide any protection in the event of a power surge.
