Phoenix Contact 3031212 ST2.5 Series Feed Through Terminal Block is designed for reliable electrical connections with a voltage rating of 800V and current capacity of 24A. It supports wire cross-sections from 0.2mm² up to 6mm², corresponding to AWG sizes 28 to 12, accommodating versatile wiring requirements.
The unit features a grey polyamide (PA) housing which provides excellent impact and abrasion resistance as well as electrical insulation to protect against electric shocks. The terminal block’s spring cage termination method offers low contact resistance of approximately 1.04mΩ for stable signal transmission and secure wire retention under vibration and thermal cycling.
With a rated surge voltage of 8kV, the terminal block ensures robust protection against transient voltage spikes, enhancing reliability in industrial electrical systems. The device is rated for operation between -50°C and 110°C, making it suitable for use in harsh and fluctuating environmental conditions.
Easy and tool-free mounting on standard DIN rails (NS 15) saves time during assembly and maintenance. The ST2.5 series terminal block is ATEX certified for use in hazardous atmospheres, expanding its applicability to environments with explosive risk.
The terminal block’s grey color and standardized size facilitate system organization and identification during installation. It complies with a wide range of international certifications and standards including NK, PRD, RS, VDE, Bureau Veritas, CCC, CSA, DNV, EAC, IECEX, KR, LR, and NEPSI, ensuring global industrial acceptance and quality assurance.
Industrial use cases include machinery building, railway applications, automation systems, and electrical distribution panels. Its robust construction and reliable performance make it an essential component in industrial and commercial electrical installations.
Durable grey polyamide housing for mechanical and electrical protection. Rated surge voltage of 8kV for transient voltage resilience. 24A current rating suitable for medium current applications. Wide temperature operation from -50°C to 110°C for extreme environments.
Tool-free DIN rail mounting convenient for installation. Compliant with multiple international standards and safety certifications. Spring cage termination ensuring low contact resistance and secure wire retention. Suitable for machine building, railway, and industrial automation applications.
