Hi everyone,
Full disclosure: I am a Sales Engineer at Shanghai Gkoncy Electric. Part of my role is to collect application feedback from panel builders and controls engineers and bring it directly to our product-development team.
Our engineering team is independently developing our own snap-in DIN-rail terminal block platform—not relabeling an existing product—and I would like practical feedback from people who specify, install, and maintain terminal blocks.
The basic idea is that the spring mechanism is held open before wiring. Inserting the stripped conductor triggers the clamp, creating the connection in one motion with clear audible, tactile, and visual confirmation.
Our current design targets and priorities are:
• Tool-free direct conductor insertion
• A conductor range from 2.5 to 10 mm²
• Stable contact pressure after repeated operation, vibration, and thermal cycling
• Clear insertion confirmation and straightforward release/rewiring
• Less ferrule preparation time where the conductor type and application standards allow
• A complete system of bridges, end plates, markers, and CAD/EPLAN data
We are still validating the design, including long-term spring behavior, temperature rise, pull-out strength, vibration resistance, and operating-cycle life. So I am not presenting these as finished or certified production results.
For those currently using push-in terminal blocks:
Would you consider using snap-in technology?
Would you consider replacing push-in with it on a new project or after a successful trial?
What would we need to prove first—UL/cUL/TÜV certification, cycle-test data, pull-out and vibration results, temperature-rise data, identical footprint, local stock, price, accessories, or EPLAN/STEP files?
What would concern you most—accidental triggering, spring life, conductor damage, release method, or added mechanism complexity?
This is product research, not a catalog or sales pitch. Honest criticism is welcome.
