Altech CTS4U terminal blocks are the most versatile terminals for wire-to-wire connection in control, automation, instrumentation and power distribution applications.

A special design feature on the flexible foot enables easy mounting and dismounting from the DIN Rail with the help of a screwdriver.

Altech terminal blocks feature screw clamps for maximum wiring efficiency and reliability.

The terminal blocks are supplied with open clamps, ready to accept wires. No special wire preparation or wire lugs are required.

Simply strip the wire, insert and tighten the screw to the torque for gas-tight, vibration resistant, solid connections.

The screw clamp design on our terminal blocks uses a tin-plated, solid copper or solid brass current bar with grooved serration, a steel cage clamp and screws.

As the clamp is tightened, the wire is pressed firmly against the current bar, ensuring positive connections every time. The steel parts are zinc plated and passivated by a golden yellow chromate layer for maximum resistance against oxidation.

When applying tightening torques, use our straight blade screwdriver to fit the screw hole guides located in the terminal block housings.

The metal parts of Altech terminal blocks are housed in precision-molded, self-extinguishing polyamide 6.6 material for maximum dielectric strength, electrical insulation and temperature resistance.

Standard features on all housings include funnel-shaped wire entry openings and screwdriver guides.
