DIN Rail Mount 4 Cage Spring Terminal Blocks - 800V 40A Electrical Connectors

We've got these in stock right now, usually ships within 3 business days if you order by noon—no cold chain needed, they're just standard electricla connectors, so packaing is simple corrugated boxes with foam inserts to keep the cages from shifting during transit.

It basically works as a tool-less spring clamp terminal block for DIN rail, rated at 800V and 40A, which is pretty standard for industrial control panels; the PA66-V0 nylon housing handles heat up to 120°C without softening, and the brass spring cage gives you that consistent contact force you want for vibration-prone environments.

dimensions are 6.2mm thick by 87mm wide and 36.5mm tall, so it fits on NS15-U type rails, and wire range covers 24 to 10 AWG—rigid up to 6mm² or soft stranded down to 0.5mm² (usually 2.5mm² is the sweet spot for most buyers). Contact resisance stays under 3mΩ, which matters more for high-current runs than people realize.

One thing we've noticed handling these is that the spring action is noticeably stiffer than some cheaper clones, so first-time users sometimes think they're forcing it, but it's actually designed that way to hold 40A steady without creep over time. Not ideal for very fine wire below 24 AWG, by the way—the spring can crush it.

Orders of 50 units or so get a small discount, and our company can do custom colors if you need a specific grey or even something like black for labeling clarity, though that adds about 2 weeks to lead time. TUV/CE/VDE/RoHS/SGS/CCC/CQC certifications are all on file, we'll include the COA with each shipment.
