STEP TERMINALS AND TERMINALS
Step terminals and terminals are fundamental components in electrical installations and control panels, serving as connection points for wiring and conductors. These devices are available in various configurations, including feed-through, ground, and disconnect types, with rated currents ranging from 2.5A to 600A and voltage ratings up to 1000V ...
Step terminals and terminals are fundamental components in electrical installations and control panels, serving as connection points for wiring and conductors. These devices are available in various configurations, including feed-through, ground, and disconnect types, with rated currents ranging from 2.5A to 600A and voltage ratings up to 1000V AC/DC. Step terminals, also known as stepped or tiered terminals, allow for multiple connection levels in a compact footprint, ideal for high-density wiring. Common materials include polyamide (PA) for insulation and copper alloys for conductive parts, with certifications like UL, CSA, and IEC 60947-7-1 ensuring reliability.
These terminals are widely used in industrial automation, power distribution panels, railway signaling, and building management systems. They are essential in control cabinets, motor control centers, and PLC/DCS systems, where secure and organized wiring is critical. Step terminals are particularly suited for applications requiring modular expansion, such as in renewable energy systems (solar inverters, wind turbines) and process industries (chemical, oil and gas). Their design facilitates easy maintenance and troubleshooting in harsh environments, with IP20 protection for indoor use.
Key subcategories include feed-through terminals (e.g., models like UK 2.5, UK 5, and UK 10), ground terminals (e.g., USLKG 3, USLKG 5), and disconnect terminals (e.g., SAK 2.5, SAK 4). Step terminals often follow a coding system like ST 2.5, ST 4, or ST 6, where the number indicates the nominal cross-section in mm². Other variants include fuse terminals, diode terminals, and sensor/actuator terminals (e.g., SAI series). These are available in gray, blue, green-yellow, and red for easy identification.
