Connection Systems - Terminal Blocks BTWI

The terminals of the BTWI line allow direct connection of different cables without requiring any tools - from flexible cables with crimped terminal to rigid bare wires.

The special shape of the terminal spring allows the safe fitting of the conductors. The contact spring opens automatically during the insertion of the conductor and ensures the necessary force to press the conductor against the current conducting bar. The structure of the spring body also ensures the progressive locking and anti-vibration of the conductor. The opening of the spring to release the conductor is performed by the driver, using a common tool with a screwdriver tip.

Connection Systems - Terminal Blocks BTWM

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

Connection Systems - Terminal Blocks BTWP

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.
