Terminal block 3001938 from Phoenix Contact has the following image attached to it.
There has been some confusion regarding the voltage capabilities of this device as it is marked with +24V on the side. However, if we look at the product attributes section on the Digikey website we can see the following ratings
3001938
Terminal Block Connector 2 Position Disconnect Black 8-26 AWG
| TYPE | Ratings |
|---|---|
| Current - IEC | 30 A |
| Voltage - IEC | 250V |
| Current - UL | 30 A |
| Voltage - UL | 300V |
Answer:
The reason this product is marked with a +24 on the side is because of the internal LED used to identify the presence of voltage within it. There are a few different versions of these to accommodate different voltage levels.
If you do not have a 24V power source and use it in an application that utilizes a higher voltage, the part does still meet the ratings above but be aware, exceeding the voltage rating will burn out the LED.
If you do not need the LED indicator the recommended course of action is to use the part that does not have an LED in it. However, if that is not possible because of sourcing issues, you could possibly use one of these other options here.
