BTWM Spring Clamp Type Terminal Blocks

The terminals of the BTWM line use the cage clamp technique. In this very simple and effective system, the connection is done by means of the stainless steel spring that constantly presses the conductor against the internal copper element.

The connection procedure is simple: the conductor insulation is removed, a screwdriver is inserted into the square hole of the terminal to compress the spring and enable access, and then the conductor is inserted into the terminal.

When the screwdriver is removed, the connection is done. The contact pressure in this connection system is uniform and independent from the user/operator, because it is provided by the spring.

Main Characteristics of the Terminals of the BTWM Line:

- Borne housing in polyamide PA66, with excellent dielectric properties and high mechanical strength

- Internal conductor element with high current carrying capacity

- Stainless steel spring

- Even contact pressure

BTWP Screw Type Terminal Blocks

The terminals of the BTWP line use the screw type connection technique. The length of insulation to be removed and the tightening torque for each terminal model are indicated in the selection tables.

When the screw is tightened, the resulting pressure deforms the terminal, locking the screw so it will not get loose. This system ensures the final quality of the connection with minimum electric losses.
