FAQ For B2B Buyers
Straight answers for purchasing and engineering teams.
What Is The Difference Between UKF1, UKF2, UKF3, UKF4 And UKF5?
UKF1 to UKF3 and UKF5 cover 1P to 4P at 20 to 63A (UKF3 also offers 45A). They differ mainly in enclosure form, terminal layout and fastener type. UKF5 uses plastic screws for specialized installs. UKF4 is the compact 1P/2P range at 10 to 35A / 250V AC.
What Does IP65/IP66 Mean On Site?
Dust-tight protection with water resistance for rain and harsh outdoor conditions. IP66 adds protection against powerful water jets. Suitable for unsheltered outdoor mounting when conduit entries are correctly sealed.
What Is The Minimum Order Quantity?
MOQ is 100 units per model. We supply distributors, OEMs and project procurement, not single-piece retail orders.
Can We Order OEM / Private Label?
Yes. Custom enclosure branding, laser-marked part numbers and neutral packaging are available for qualified wholesale programs.
Which Standards And Certificates Apply?
All UKF switches comply with IEC 60947-3. Available marks include CE, UKCA, CB, SEMKO, SAA, CQC, CCS and RoHS. IP test certificates can be provided for project files.
