Connection Terminal Blocks
Connection terminal blocks are available in screw, Push-X, spring cage, push-in, COMBI plug-in, QUICKON insulation displacement, and bolt connection technologies from Phoenix Contact in feed-through, disconnect, fuse, high-current, hybrid, miniature, plug-in, sensor, actuator, and transformer configurations for DIN rail wiring in industrial control panels, automation systems, and machinery.
RSP Supply carries a full line of connection terminal blocks designed for secure and organized wire management in control panels, automation systems, and machinery. These components provide stable electrical connections, enable efficient wiring layouts, and simplify installation and maintenance across power and control circuit applications. Phoenix Contact CLIPLINE complete terminal blocks offer a high degree of flexibility through freely combinable connection technologies using the double function shaft, with uniform bridging, marking, and test accessories that reduce logistics costs and individual part counts 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. The 1.5mm² Push-X nominal cross-section supports 0.34mm² to 2.5mm² conductors at 17.5A and 500V, while the 4mm² Push-X version supports 0.5mm² to 6mm² conductors at 32A and 500V. Plug-in terminal blocks with COMBI plug-in zones and Push-X connection support conductor cross-sections from 0.5mm² to 4mm² at 24A and 800V with up to 15 position configurable COMBI connectors for fast field-level connections using preassembled cables. Screw connection terminal blocks provide maximum contact force and maintenance-free performance through the Reakdyn principle, accommodating copper conductors up to 240mm² without pretreatment. Spring cage terminal blocks provide reliable vibration-resistant connections for applications with mechanical stress or movement.
Modular and multi-level terminal blocks allow scalable configurations that adapt to changing system needs, while miniature and micro terminal blocks support high-density panel layouts where space is limited. All Phoenix Contact terminal blocks are tested throughout the manufacturing process and approved for a wide range of national and international standards, exceeding requirements for long-term stability, reliability, and environmental resistance.
FAQs
Q: What are connection terminal blocks used for?
Connection terminal blocks are used to connect, organize, and distribute electrical wires securely within control panels, automation systems, and machinery for both power and control circuit applications.
Q: What is Push-X technology and how does it benefit terminal block wiring?
Push-X technology uses a factory-pretensioned contact spring for tool-free wiring of rigid and flexible conductors with or without ferrules from 0.34mm² to 25mm², with visual and acoustic connection confirmation and easy conductor release using the orange actuating push button.
Q: What connection technologies are available in Phoenix Contact terminal blocks?
Phoenix Contact CLIPLINE complete terminal blocks are available in Push-X, screw, spring cage, push-in, COMBI plug-in, QUICKON insulation displacement, and bolt connection technologies that can be freely combined using the double function shaft.
Q: Can connection terminal blocks handle high-current applications?
Yes. Phoenix Contact high-current terminal blocks and screw connection types support copper conductors up to 240mm² cross-section, accommodating a wide range of current and voltage requirements in both low and high-power circuits.
Q: Are DIN rail terminal blocks easy to install and modify?
Yes. Phoenix Contact CLIPLINE complete terminal blocks snap directly onto standard DIN rails with standardized bridging, marking, and test accessories shared across the system, simplifying installation, commissioning, testing, and future panel modifications.
