Ideal 30-211 Connector Set

The Ideal 30-211 Mechanical Connector Set provides 100 brass set-screw connectors rated for 16-12 AWG copper wire. Each unit accepts a single conductor and terminates with a slotted head for a 3/16 in stud. The brass body is coloured black and operates up to 150 degrees F at 600 V maximum. Electricians and panel builders use these for secure, repeatable terminations in control cabinets and junction boxes.

Thermal and Electrical Behaviour

Brass construction gives a low-resistance path that runs cool under normal 600 V loads up to the 150 degree F limit. The set-screw clamp maintains contact pressure without spring fatigue, so resistance stays stable through thermal cycles. No moving parts or insulating barriers mean there is no audible noise and no extra power draw beyond the circuit itself. Installation torque is applied once with a standard slotted driver.

Build Integration

Each connector occupies a single 0.19 in hole on a 3/16 in stud, leaving adjacent positions free for dense rail mounting. The 6.000 length allows straight wire entry without sharp bends, saving space in tight enclosures. The pack of 100 covers multiple panels from one box, reducing re-order frequency. Buyers needing multi-conductor blocks or spring-cage terminals will need a different product family.

Questions about this item

How do I install these 30-211 set-screw connectors on 16-12 AWG copper wire?

Strip insulation, insert the stripped conductor into the brass barrel, then tighten the slotted set screw with a screwdriver until the wire is firmly clamped; the step often missed is verifying no insulation is caught under the screw.

What maintenance or replacement will these brass connectors need over time?

Inspect periodically for screw loosening or oxidation; re-torque the slotted set screw if it has backed out, and replace any connector showing corrosion or overheating discoloration on the brass body.

What is the first limit reached when these connectors run continuously at high load?

The 150 °F maximum operating temperature is typically the first limit encountered under sustained current, so ensure ambient temperature plus conductor heating stays below that threshold.
