Component Terminal Blocks

RSP Supply carries a full line of component terminal blocks designed to simplify wiring, improve safety, and save space in control cabinet applications. These specialized terminal blocks go beyond basic wire termination by incorporating key circuit components such as fuses, diodes, and disconnect features directly into their design.

Fuse terminal blocks integrate fuse holders into the block, providing overcurrent protection without the need for additional components. They feature easy fuse replacement and visual indicators for blown fuses, ensuring quick maintenance and system reliability. Diode terminal blocks include built-in diodes that prevent reverse current flow, protecting sensitive electronic components from potential damage and ensuring stable circuit operation. Disconnect terminal blocks enable simple and secure circuit isolation for testing or maintenance without disconnecting the wiring, improving safety and efficiency during service work.

Component terminal blocks help create organized, compact, and reliable wiring layouts in automation, control, and power distribution systems. Mounted on DIN rails, they ensure durable, vibration-resistant connections suitable for modern control cabinets.

FAQs

Q: What are the benefits of component terminal blocks compared to standard terminal blocks?
Component terminal blocks combine termination and circuit functionality, such as fusing, isolation, or diode protection, into one unit, saving space and simplifying wiring.

Q: Can component terminal blocks be used in control cabinets?
Yes. They are specifically designed for control cabinet applications, offering organized and space-efficient wiring with integrated safety functions.

Q: What connection technologies are used in component terminal blocks?
They support various connection methods, including screw, spring-cage, and push-in technology, depending on the application and required installation speed.

Q: What does “rated cross section” mean?
The rated cross section indicates the maximum wire size a terminal block can safely accommodate, based on its electrical and mechanical design.

Q: Do component terminal blocks support multiple wire sizes?
Yes. Many models allow for mixed wiring sizes, offering flexibility when connecting different conductors within a single system.
