Reliable Spring-Clamp Connections for Industrial Panels
Spring-clamp terminal blocks maintain electrical contact by applying continuous spring pressure to the conductor. Unlike connections that depend on manually applied screw torque, the spring mechanism provides consistent clamping pressure and automatically compensates for conductor creep, helping maintain a secure electrical connection throughout the service life of the installation.
The Entrelec SNA range is designed for industrial control and distribution applications where reliable connections and efficient use of panel space are essential. The DB2.5/5.2L combines front conductor access, compact dimensions and a broad conductor capacity, making it a practical choice for machine builders, panel builders and industrial automation engineers.
Typical Applications
- Industrial electrical control panels.
