Explore the technical specifications and compatibility of PC250 terminal blocks. Compare ratings, wiring options, and local selection advice for students, makers, and engineers.
Current, voltage, pitch, and wire size needed for safe, reliable connections.
How to match PC250 terminals with other connectors and typical South African wire gauges.
Local availability, lead time, and use cases for students, industry, and prototyping.
PC250 terminal blocks are a widely used family of pluggable or fixed PCB connection blocks. With a typical pitch of 5.0mm or 5.08mm, they provide safe, quick, and secure wire-to-board terminations for low-to-medium current electronic applications. Their screw clamp or push-in mechanisms are ideal for field wiring, panel builds, industrial automation, and prototyping work, especially for South African makers and engineers needing robust, proven connectivity.
| Parameter | Typical Value / Range | Notes |
|---|---|---|
| Pitch | 5.0mm / 5.08mm | Matches common PCB layouts; confirm datasheet before designing footprint |
| Current Rating | 10A - 16A | De-rate for higher temperatures; check brand-specific data |
| Voltage Rating | 250V AC/DC | Typical for the PC250 class; verify insulation specs for safety |
| Wire Size (mm2) | 0.2 - 2.5mm2 | ~24-12 AWG; widely compatible with South African wire sizes |
| Mount Type | Through-hole PCB | Straight or right-angle options available |
| Clamp Series | Screw, rising cage or push-in | Screw types most common in SA industrial and academic labs |
Compatibility is determined by pitch, current, and the physical fit for both PCB and wires. PC250 terminals are widely compatible with Eurostyle connectors in industrial controls, laboratory equipment, and home automation builds. When selecting, confirm:
These are found in Communica's terminal blocks section with varying configuration and pole counts.
Suppose you are building a power distribution board for a student robotics challenge. You need four output terminals capable of carrying 6A at 24V DC per channel. The PC250 block (rated 16A, 250V AC) offers more than enough capacity. Use 1.5mm2 wire (common in SA) and standard 5.08mm pitch for easy match with perfboards and custom PCBs. If vibration is a risk (on a mobile robot), a fixed soldered terminal type is best.
