DIN-rail mounted Terminal Blocks (DINnectors)

The AutomationDirect DINnectors line of terminal blocks have reached a price breakthrough level. Now you can buy terminal blocks below distributors' cost!

DINnectors are simply DIN rail-mounted connectors or terminal blocks. They provide a means of connecting and identifying two or more wires within the demands of an industrial environment. DINnectors can terminate solid or stranded wires ranging from 18-3/0 AWG, and offer fusing, grounding or disconnecting capability within the terminal block itself.

Rather than limiting you to a fixed number of terminations, most DINnectors are modular in design, allowing you the freedom to mix as many combinations of types, wire sizes and quantities as can fit on a mounting rail. And, rather than limiting you to proprietary terminal block mounting rails on which only a single manufacturer's terminals can be utilized, DINnectors mount on the universal DIN rail. The DIN rail is the internationally approved, industry standard mounting rail for components made by hundreds of manufacturers worldwide. The AutomationDirect range of DINnectors terminal blocks is internationally approved by various national and international standards organizations such as UL, CSA, VDE, SEV, RINA and IEC. The DINnectors line includes a wide range of connection products to help you wire your control panels:

  • Feed-through blocks
  • Multi-level blocks
  • 3-tier blocks for high-density and sensor wiring
  • Ground blocks
  • Disconnects and fuse blocks
  • Mini blocks
  • LED and diode blocks

Three different types of DIN rails

  • 35 mm slotted
  • 35 mm slotted high (deep-dish)
  • 15 mm slotted
  • Angled support brackets for easy wiring access
  • Insulated ferrules, ring and fork terminals, butt and end connectors

SCREWLESS TERMINAL BLOCKS

AutomationDirect also offers a line of screwless DINnector terminal blocks featuring a range of models, including feed-through, double-level, one-to-two connection, two-to-two connection, knife blade disconnect, and screwless ground terminal blocks. A line of accessories, including DIN-rail, end brackets and covers, angled support brackets, jumper bars and marking accessories, rounds out the offering. Prices for the screwless terminals start at $0.43 per piece (sold in quantities of 10, 25, or 50 per box).

POWER DISTRIBUTION BLOCKS

The distinctly different styles of short-circuit current rated (SCCR) power distribution blocks and terminal blocks support different application requirements. Finger-safe power distribution blocks are engineered to accept copper conductors and maintain an SCCR rating of 200kA, with proper fusing. These blocks are suitable for both factory and field wiring and are rated from 175A to 760A. Finger-safe blocks start at $8.25.

Open-style terminal blocks are engineered to maintain an SCCR rating of 200kA with copper conductors and 10kA for aluminum conductors. Ampere ratings of up to 760A make these blocks ideal for use in UL508A panels for branch circuit applications. The terminal blocks, starting at $6.75, are available in single, double, and three-pole configurations. Safety covers are also available, starting at $1.50.

  • Open-Style Terminal Blocks

Short-Circuit Current Rated Power Distribution Blocks

We offer distinctly different styles of short-circuit current rated (SCCR) power distribution blocks (PDBs) and terminal blocks (TBs) to match different application needs. The differences are whether the power distribution blocks are enclosed or not, and whether they are UL1953 Listed PDBs or UL1059 Recognized TBs, which have different minimum spacing requirements.

Why is this important?

  • Assembly short-circuit current ratings (SCCRs) are now required in the 2005 NEC® and UL508A Listed Industrial Control Panels.
  • Marking the SCCR on Industrial Control Panels (NEC® 409.110), Industrial Machinery Electrical Panels (NEC® 670.3(A)), and HVAC equipment (NEC® 440.4(B)) is now required by the National Electrical Code.
  • Power distribution blocks or terminal blocks not marked with an SCCR are typically one of the weakest links and may limit an assembly to no more than 10 kA SCCR.
  • The EPDB Series has increased spacing required where used in feeder circuits in equipment listed to UL508A (UL1059 terminal blocks must be evaluated for proper spacings).
  • Also, for building wiring systems, the EPDB Series power distribution blocks can be used to meet the 2005 NEC® requirements in section 376.56(B) for power distribution blocks in wireways.

Open-Style Terminal Blocks

Open-style terminal blocks for cable termination

Open-style terminal blocks are a convenient way to manage your power distribution needs.
