IEC 60309 Connector Validator
Check amperage, voltage, and pole combinations against IEC 60309. Shows connector color and keyway position.
What this tool checks
Checks
- ✓ Whether the amperage, voltage, and pole combination is a standard IEC 60309 configuration
- ✓ Connector color assignment per the standard (blue, red, yellow, black, violet, white)
- ✓ Keyway (earth contact) clock-hour position
- ✓ Valid pole configurations for each voltage range
- ✓ Optional keyway input cross-checked against the standard position
Does not check
- ✗ Specific amperage/housing size compatibility
- ✗ IP rating of the connector housing (IP44, IP67, etc.)
- ✗ Whether the connector is a plug, socket, inlet, or appliance coupler
- ✗ Cable entry size or terminal capacity
- ✗ Country-specific installation rules or derating factors
