The 387207203: The 15A current rating at 300V is typical for a 0.375" pitch barrier block — the pitch provides enough creepage distance for the voltage rating without forcing an oversized board footprint. The 14-22 AWG wire range means it handles both 14 AWG for motor or heater loads and 22 AWG for control signals, all under the same screw clamp. The nickel-plated brass screws resist corrosion in industrial atmospheres.

Frequently asked questions
Will the 387207203 drop into a panel designed for the 387206304?
Yes, if the panel requires 3 circuits instead of 4. Both share the same 0.375" pitch, 15A rating, 300V rating, screw top termination, PC pin bottom, and UL94 V-0 black housing. The only difference is circuit count.
Where can I buy the 387207203 and get a price?
The 387207203 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
