We’ve been running into clearance issues on a control panel retrofit where every millimeter of DIN rail space counts, so the 68×62×6.2mm footprint of this multi-level block is pretty much exactly what we needed to stack three circuits in the same slot.
It handles 0.2 to 4mm² solid or stranded wire with a screw clamp that holds firm at 32A and 500V—better than the spring-clamp alternatives we tested for vibration-prone environments since the screw doesn’t loosen over time.
The PA66 housing is rated flame resistant and meets IEC 60947-7-1, which is the standerd our safety auditor flagged after last year’s inspection; most buyers go with the grey variant for labeling clarity, but we’re ordering blue to differentiate motor circuits.
We’ve used these from this suppiler before, so I know the brass conductor is nickel-plated (not just bare brass like some knockoffs) and the COA reliably quotes 4mm² cross-section with a tolerance that actually passes our torque tests.
Lead time is usually 2-3 weeks for grey, but blue might take a bit longer since it’s not a stock color—I confirmed they have 50-pcs boxes, which suits our prototype batch better than the 1500-pcs carton.
CE and CQC certs are listed, though I’d get them to email the RoHS declaration seprately since our compliance team needs batch-specific document, not just a generic PDF.
PA66 nylon typically handles continuous operation up to 105-120°C, but for flame-resistant grades like ours, it's rated for short-term peaks around 150°C. We recommend staying within 85-100°C for long-term reliability to avoid degradation.
Yes, both CE and CQC certificates are on file and cover this JUKKB 5 model with the 4mm² rating. They are not generic—they specifically reference the IEC 60947-7-1 standard for this product line. We can share them upon request.
Absolutely, we offer custom color options like green, yellow, or red. The MOQ for custom colors is usually 5000 pieces per color, and lead time adds about 10-12 working days.
The 0.2-4mm² rating covers both solid and stranded (soft) cable. For stranded wire, just make sure to fully insert it into the clamp and tighten to the recommended torque to avoid loose connections.
Standard stock orders of 1500 pieces (one carton) ship within 3-5 working days. They come packed as 50pcs per box, 30 boxes per carton—so you get individual boxes for ease of handling, not just a bulk bin.
