Modular Screw Clamp Terminal Block
The Cembre TBS16-BU is a modular screw clamp terminal block from the TBS series. The product features a blue insulating PA6.6 body and provides two electrical connections in one unit. The terminal block is designed for mounting on NS35 DIN rails and uses an M4 screw as the clamping element.
Design and Function
The TBS16-BU has a screw clamp design with a captive screw and a specified maximum tightening torque of 1.2 Nm for the M4 screw. The terminal is rated with a nominal current of 76 A and a maximum voltage class up to 1000 V according to IEC 60947-7-1. The construction includes conical wire entry openings (as described for the TBS series) and a solid CRCA steel conductor clamp to ensure electrical connection.
