You've got a panel build where you're running 60A feeds to multiple motor starters and really don't want to spend all day wrestling with ring terminals or worrying about loose connections—this TBR series is what we'd grab off the shelf for that job.
We're using a copper conductor core with a flame retardant housing that's rated from -40°C to +105°C, and the cutter head screws bite into the wire to give you contact resistnce under 5mΩ (usually well below that in practice), with insulation resistance north of 100MΩ and dielectric strength tested at 3000V AC for a minute.
It's a dual hole screw terminal mounted on DIN rail—side entry design makes it quicker to wire than front-entry blocks—but honestly, IP20 protection means you don't want this in wet environments or where dust is heavy; it's fine inside a control cabinet for industiral control systems or power distribution, but don't use it outdoors without an enclosure.
We stock these from 5A up to 200A, with pitch ranging form 5.0mm to 10.5mm depending on the model—most buyers go with the 100A version for general distribution work.
Ordering is pretty straightforward: just tell us current rating and how many pieces you need, we'll confirm lead time (usually 20 days or so), and we'll ship with COA for CE and RoHS compliance.
They're CE and RoHS certified, so you're covered for European market compliance and environmental standards. No extra paperwork needed on your end.
Our MOQ is usually 100 pieces per model, but we can flex a bit for first-time orders or samples. Just let us know the quantity you're targeting.
Current rating goes from 5A to 200A depending on the specific model. The wire range also scales with it, from 0.5mm² up to 100mm². Pick the rating that matches your load.
Yes, we include the 3000V AC/min dielectric strength test report with each batch. It's standard quality documentation we supply for traceability.
Typically 15-20 working days after order confirmation. Stock models ship faster, but we'll confirm exact timing once we know the model mix.
