- Select the housing colour coding used in your panel standard
Frequently asked questions about the JK300R-500 PCB Terminal Block
What wire range does this accept?
The accepted conductor range is listed in the specification table above. If your conductor is outside that range, contact us with the cable size and we will recommend the correct frame.
Are these suitable for high-vibration installations?
Spring-cage and push-in terminations resist loosening better than plain screw terminals under vibration. Specify the spring type for mobile, marine or rail applications.
Can I order mixed sizes in one shipment?
Yes. Mixed-size and mixed-colour orders are normal for this product family; send your picking list and we will quote the combined quantity.
What packaging do they ship in?
Standard export cartons with the quantity per box shown on the label. Custom labelling and buyer-branded boxes are available on qualified volumes.
