3 PHASE THYRISTOR
The three‑phase thyristor power regulator by Denki Seigyo is an industrial‑grade power control module designed for precise regulation of three‑phase AC loads. It utilizes robust thyristor (SCR) switching to modulate voltage and power to heavy-duty loads—such as large heaters, motors, induction furnaces, ovens, and other three‑phase industrial equipment. Built to deliver high reliability, smooth power adjustment, and long‑term performance in harsh production environments.
32A 500V 4(6)mm2 32A double Push-In Spring Terminal Blocks
Characteristics
●Push-in spring terminal blocks use tool-free push-in connection technology and are suitable for various wiring scenarios.
●The most prominent advantage of this product is easy to operate, no tools are required, and the insertion force can be saved by 50%.
●When rigid conductors from 0.25 mm2 or conductors with ferrules from 0.34mm2 are inserted, the contacts pring is automatically opened.
●Required pressure force against the currnt bar
●To helease or connect flexible conductors from 0.14mm2 without ferrules, any tool can be used to operate the integrated push button easily without direct contact with live parts.
●The connection method has been tested may times and obtained a series of certifications.
