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.
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
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.
Ready to use Enclosed Full Voltage magnetic starters are the most commonly used devices to switch AC motor loads.
WEG's non-reversing non-combination starter consisting of a contactor and a bimetallic overload relay assembled together inside a NEMA type 1 enclosure. Two optional pilot devices are available factory-mounted.
Either START / STOP pushbuttons or no-pilot device on the cover are on the shelves ready to go. Field Kit modifications are also available as accessories.
The MSW Switch-Disconnectors enable the manual drive of motors, machines and other equipment. Available in versions to mount on panel doors or base with currents up to 160A.
The MSW Switch-Disconnectors were developed according to IEC60947-3 and UL508, enable carrying and interrupting electric currents under normal or overload conditions and provide complete physical insulation between the circuit and the power supply when in OFF position.
The RNW, WEG level control relay, is an electronic control device that allows monitoring and automatic setting of level of conductive (non-explosive) liquids by means of submerged electrodes. It has front selector that allows adjusting the electronic circuit to the resistivity of the liquid.
WEG RPW relays are electronic devices that protect the three-phase systems against phase loss or neuter loss (selectable) (RPW FF), phase sequence inversion (RPW SF) or both functions integrated in the same product (RPW FSF). Whenever an anomaly occurs in the system, the relay will switch its output to interrupt the motor or process to be protected. Designed according to international standards, the RPW is a compact and safe solution in 22.5-mm wide boxes for mounting on DIN rail 35mm.
Standards: IEC / EN 60947-1 and IEC / EN 60947-5-1
WEG RTW timer relays are electronic devices that allow, due to adjusted times, to switch an output signal according to its function. Commonly used in the automation of industrial processes and machines like motor starters, control switchboards, industrial ovens, casting machines, among others.
It has digital electronics, which provides high accuracy, repeatability and noise immunity.
Designed according to international standards, the RTW is a compact and safe solution in 22.5-mm wide boxes for mounting on DIN rail 35mm, in configurations with 1 or 2 NONC outputs and supplied with 110-130V 50/60Hz, 220-240V 50/60Hz or 24Vdc.
