Push-in DIN Rail Terminal Block

Push-In Din Rail Terminal Block for Industrial Automation | Fast Wiring, Spring Clamp Connection

Avantar's Push-In Din Rail Terminal Block features a factory-calibrated 301 stainless-steel spring that locks wires on insertion – no screwdriver, no torque tool, no re-tightening. Supporting wire diameters from 0.5 mm2 to 16 mm2 on standard DIN 35 mm rail let panel builders work faster without compromising connection reliability. Available in grey, blue, red or bespoke RAL colours and UL 486A/B, CE, RoHS compatible Shipment from Guangdong in 7-15 working days.

What Makes This Terminal Block Different?

Standard screw terminals need torque tools and periodic retightening. This push-in spring terminal block solves both difficulties with a 301 stainless-steel spring that automatically applies a continuous contact force after a wire is introduced.

The spring clamp accommodates solid wire and ferrule-ended flexible wire without tools. Panel builders manually insert wires and verify the connection with a light pull test and go on. No torque fluctuation, no rework.

Key Features

The product is built around design principles that matter most to panel builders and procurement engineers:

• Tool-free insertion — solid and ferrule-ended conductors insert by hand in seconds
• Spring clamping — 301 stainless-steel spring maintains constant contact force under vibration and temperature cycling
• DIN 35 mm rail mount — fits standard EN 60715 rail directly
• Wide wire range — accepts 0.5 mm² to 16 mm² wire cross-sections
• Compact footprint — more wiring positions per linear rail meter versus screw-type blocks
• PA66 UL94 V-0 housing — flame-retardant, rated for industrial environments
• Tin-plated copper conductor bar — corrosion-resistant, low contact resistance

Technical Specifications

Applications

These terminal blocks are perfect for all situations where wire density and connection reliability are of concern.

The most common application is PLC and automation cabinets – tool-less insertion speeds up panel assembly on high density boards. Vibration resistant spring clamping provides reliable connections that do not need maintenance re-torquing. Perfect for HVAC control panels, solar inverter enclosures, wind turbine junction boxes and building automation systems.

The stainless-steel spring construction compensates for dimensional changes due to mechanical vibration and temperature cycling in railway and heavy equipment applications ensuring stable contact resistance without planned re-tightening.

Custom Design Options

Avantar provides OEM & ODM customers with the option to modify. Housing in normal colour grey RAL7035 Custom RAL colours are available on purchases of 5,000 units or more.

Options for markings include laser engraving and pad printing of your part numbers or logos, and custom printed marker strips. OEM branding, private label packaging: Your logo can be incorporated into the housing mould.

Functional customisation is also available: specialist spring materials for high temperature circumstances, unique wire entrance angles and pre-integrated electronics components; MOQ for custom marking is 500 pcs, Lead time 10-15 working days. All modified items will still be IEC and UL certified.

How to Specify?

Selecting the right Push-In Din Rail Terminal Block requires confirming a few parameters before ordering.

Step 1 — Wire size: Confirm the conductor cross-section range you need (0.5–16 mm²). For flexible cables (Class 5 or 6), specify ferrule-ended entry.

Step 2 — Current rating: Match terminal model size to your circuit's current demand. Current ratings vary by model; request the datasheet for the specific size you need.

Step 3 — Color and marking: Select from standard gray, blue, or red housing, and specify any custom label text, numbering sequence, or RAL color.

Step 4 — Quantity and lead time: Standard orders ship in 7–15 working days. Custom colors or OEM marking require 10–15 working days from order confirmation.

Step 5 — Certifications: Confirm whether your project requires UL, CE, RoHS, IEC 60947-7-1, or additional regional certifications. Compliance documentation is available on request.

FAQ

Q: What is a push-in spring terminal block and how is it different from screw type terminals?

A: The push-in spring terminal block can be mounted on standard 35 mm DIN rail according to EN 60715. Instead of a screw, the terminal block uses a stainless steel spring clamp. Hand insertion, no tools required. Solid or flexible wire with ferrule ends. The spring is calibrated in the manufacturing to make the connection quality independent of the worker’s torque technique. Release wire by pressing release button with small screwdriver and pulling conductor out.

Q: Do I need to use wire ferrules with push-in spring terminal blocks?

A: Solid Class 1 single-core wire inserts directly and no ferrules are required. Stranded wire of Class 7 standard should be ferruled to avoid strand dispersal. Insulated ferrules are required in Class 5 fine-stranded and Class 6 extra-fine flexible cables before insertion. Use tinned copper ferrules of the appropriate length to match the terminal insertion depth. Strip insulation to the appropriate length. Insert firmly until the wire bottoms out and execute a light pull test to check latching.

Q: How do these terminal blocks function under vibration and temperature cycling?

A: Screw-type terminals will experience loss of clamping force over time under vibration and temperature cycling owing to thread micro-movement and conductor creep and will require frequent re-torquing. The stainless-steel spring in this push-in design automatically compensates for dimensional changes caused by temperature fluctuation and mechanical vibration, offering stable contact resistance under IEC 60068-2-6 vibration conditions and in the -40°C to +85°C operating range without scheduled maintenance.

Q: What industries and applications use this product most?

A: The product is used in PLC cabinets, industrial automation panels, HVAC systems, solar inverters, wind-power equipment, building automation, railway applications and heavy-duty machinery. It suits any application where quick and dependable wiring and vibration resistance are the goals.

Q: Is it possible to customise housing colours and OEM branding using Avantar?

A: Sure. The standard housing is RAL7035 grey. Custom RAL colours available on orders of 5,000 units or more. We can laser engrave or pad print customer part numbers and logos. OEM logos can be included onto the housing and private label packaging can be supplied. The MOQ for customisation is 500 pcs with 10-15 working days lead time.

Q: What are certifications of your terminal blocks?

A: Our terminal blocks are UL 486A/B, IEC 60947-7-1, CE, RoHS and ISO 9001 compliant. We can assist your purchase and regulatory approval procedure with full compliance documents accessible upon request.
