High-Quality AMUR Terminal Blocks H U W V Type for Electrical Conductivity and Industrial Use

We usually handle these in OEM or AMUR branding, and the 4mm2 copper conductors sit in a cold-pressed square body 380V—the white shell isn't just cosmetic, it generally indicates a cleaner alloy formulation for conductivity. Most buyers go with the 4mm2 for control cabinet work, though we've had some push it in smaller junction boxes where space is tight.

Cold pressing gives the copper a consistent density you don't always see with cheaper stamped blocks, and that matters when you're torquing down screw terminals repeatedly. The interface is screw-type—they're not spring-loaded or lever-style, so plan for a screwdriver in your assembly. Available in H, U, W, and V configurations, but check lead time if you need a mix across all four on a single PO.

We've seen these used mostly in factory control cabinets and industiral panel builds (usually 380V three-phase distribution). They're better than generic blocks for environments where vibration could loosen a cheaper terminal—the square shape lets you mount them flush against the rail or panel wall. We typically quote with a 7-10 day lead time, give or take depending on quantiy and whether we need to pull from two or three manufacturing lots.

MOQ usually runs at 500 units per type, though our company can flex on that for repeat orders. We ship with COA and batch traceability—that's standard on any order over $1,000 or so. We don't have the TDS for these in English every time, but the HPLC and phyiscal test reports are on file; just request them in your order notes.

Payment standard is 30% deposit, 70% before shipment for new accounts—basically, we don't do open terms on first orders under $5,000. roughly 15-20 days from deposit confirmation, with sea freight adding 25-35 days depending on your port. Air freight is also an option if you're in a pinch, but expect shippng to run about 40% of the product value.

For smaller quantities under 100 pieces, our typical inventory covers the AMUR-branded units immediately. You'll sometimes get a slightly tighter tolerance on the screw thread than what you see with unbranded equivalents—that's not on the spec sheet but it's noticeable if you're doing high-volume torquing. And one thing to know: these blocks aren't ideal for high-frequency switching environments; they're better suited to static connections where vibration stays moderate.
