65A at 600V from finger

Sep 17, 2023

EBY Electro has created a pcb-mount finger-flick terminal block rated at 65A and 600V.

Part of a family, EB4220-xx-x01 mounts on a 15mm pitch and is 35 deep and 30mm high – 44mm above-PCB clearance is needed for lever operation.

"The stainless steel spring clamp system has a patented ergonomic lever design for finger-friendly, tool-free wiring. The mounts are angled for easy wire entry," according to distributor Omni Pro, which is stocking the terminals.

Contacts are copper matte tin over nickel and, for mechanical strength, the PCB interface has four pins per contact. Various pole counts up to 12 are available.

Wires from 6 to 16AWG can be handled (strip length is 12 – 13mm), and there is a provision at the rear (slot in photo) for jumper to short adjacent circuits together.

Operation is over -40 to +115°C (soldering 260°C for 5s) and the terminal with withstand 2.2kVac (60s test).

White UL94V-0 thermoplastic is used for the lever and the body is polyamide in a choice of eight colours.

A 10mm pitch 55A 300V version is also available, and EB4120 is a series with the same 65A 600V or 55A 300V options, but without provision to short adjacent circuits so it takes up a little less room front-to-back.

Applications are foreseen in motor controls, industrial switching equipment, solar power and the marine industry.
