Terminal Block for Branching
The TQB series is a high-capacity terminal block designed for branch circuits.
Compared with conventional branch wiring using copper bus bars, it reduces labor time by about one-sixth and installation space by approximately 15%.
Because it is a modular structure without side bases, it achieves excellent space efficiency.
All models are rated with consideration for the use of heat-resistant wires.
