Branch Terminal Blocks
Branch terminal blocks are available in 7.7mm and 12mm widths from Phoenix Contact and Weidmuller with screw, spring cage, push-in, Push-X, fast-connect, COMBI plug-in, and barrier connection technologies for secure, modular wiring of feed-through, disconnect, fuse, high-current, sensor, and actuator circuits in industrial control panels and automation systems.
RSP Supply carries a full line of branch terminal blocks in 7.7mm and 12mm widths designed for secure and organized electrical connections in control panels and automation systems. These terminal blocks provide reliable connectivity for complex control circuits, allowing multiple outgoing wires to connect to a single incoming wire within a compact, insulated DIN rail mounted frame. Each terminal block uses a clamping component and conducting strip to secure and organize wiring with nominal voltages up to 800V and current ratings up to 32A depending on the connection technology and conductor cross-section selected.
Phoenix Contact CLIPLINE complete terminal blocks offer a high degree of flexibility through freely combinable connection technologies using the double function shaft, with standardized bridging, marking, and test accessories across all terminal block types. Push-X terminal blocks enable tool-free wiring of rigid and flexible conductors from 0.34mm² to 25mm² without ferrules, with factory-pretensioned contact springs providing visual and acoustic connection confirmation and easy conductor release using the orange actuating push button. Screw connection terminal blocks provide maximum contact force and maintenance-free operation through the Reakdyn principle, accommodating copper conductors up to 240mm² cross-section without pretreatment. Plug-in terminal blocks with COMBI plug-in zones and Push-X connection combine tool-free control cabinet wiring with fast field-level connection using preassembled COMBI connectors in up to 15 positions.
Branch terminal blocks are ideal for creating semi-permanent wire connections that can be easily switched out for maintenance, upgrades, or inspection. Mounted securely on DIN rails, they can be added or removed without disturbing existing wiring, making them well-suited for efficient field modifications and system expansions in manufacturing, automation, water and wastewater, oil and gas, and commercial building control applications.
FAQs
Q: What is the purpose of a branch terminal block?
A branch terminal block allows multiple outgoing wires to be connected to a single incoming wire, streamlining wiring organization and control circuit layout in industrial control panels and automation systems.
Q: What connection technologies are available in branch terminal blocks?
Connection options include screw, spring cage, push-in, Push-X, fast-connect, COMBI plug-in, and barrier types to suit specific application requirements, conductor types, and wiring preferences.
Q: What is Push-X technology in Phoenix Contact terminal blocks?
Push-X technology uses a factory-pretensioned contact spring for tool-free wiring of rigid and flexible conductors with or without ferrules, providing visual and acoustic connection confirmation and easy conductor release with the orange actuating push button.
Q: What are the available widths for branch terminal blocks?
Branch terminal blocks are available in 7.7mm and 12mm widths from Phoenix Contact and Weidmuller, providing flexibility for different wire sizes, current ratings, and space constraints in control panel installations.
Q: How are branch terminal blocks mounted in control panels?
Branch terminal blocks snap directly onto standard DIN rails, providing secure and modular installation with easy access for maintenance, modification, or system expansion without disturbing existing wiring.
