Panel Feed-Through Terminal Blocks
Panel feed-through terminal blocks provide a reliable and organized method for connecting and distributing wiring within electrical control panels. These non-fused, non-grounded terminal blocks are designed to create secure pass-through connections between incoming and outgoing conductors, making them ideal for applications where circuit protection and grounding are handled elsewhere in the system.
Terminal blocks feature an insulated housing with an internal conductive path and a clamping mechanism that securely holds conductors in place. Common connection styles include screw clamp, spring cage, push-in, fast connection, and barrier-style terminations. This modular design allows multiple outgoing wires to be connected to a single incoming conductor while maintaining a clean, serviceable layout inside the enclosure.
Mounted directly onto DIN rail or mounting rail systems, panel feed-through terminal blocks can be easily added, removed, or rearranged without disturbing adjacent wiring. This flexibility makes them well suited for control panels, automation systems, and industrial equipment where future modifications, troubleshooting, or inspections are expected.
FAQs
Q: What is a panel feed-through terminal block?
A panel feed-through terminal block is a modular wiring component that connects two conductors together, allowing electrical signals or power to pass through a control panel in an organized and secure manner.
Q: What does non-fused and non-grounded mean?
Non-fused terminal blocks do not include an internal fuse for circuit protection, and non-grounded terminal blocks do not provide a grounding path to the panel. Protection and grounding are handled elsewhere in the electrical system.
Q: How are wires connected to feed-through terminal blocks?
Wires can be connected using several methods, including screw connections, spring cage clamps, push-in connections, fast connections, or barrier terminals that require ring or spade lugs.
Q: How are terminal blocks mounted inside a control panel?
Most panel feed-through terminal blocks snap securely onto standard DIN rail or mounting rail systems, allowing for easy installation and reconfiguration.
Q: Are feed-through terminal blocks suitable for complex control circuits?
Yes, feed-through terminal blocks are commonly used in complex control circuits because they help organize wiring, simplify troubleshooting, and allow circuits to be modified without disturbing other connections.
