Product standards in North America and in some other countries have a different emphasis from those in Europe. This is because UL standards apply here. UL (Underwriters Laboratories Inc.®) is one of the leading organisations for testing and certification in the area of product safety.
Since 2019, Doepke has been expanding its production of miniature circuit-breakers and therefore also its product portfolio: the three product series DLS 7, 8 and 9 are optimised for various applications in industry and plant engineering. All three series are certified to their own UL standard and are therefore easy to tell apart. In addition to this certification, all three series offer maximum space gain thanks to their compact design, which is convenient for wiring. The special busbar system enables easy and fast installation in the network. What’s more, it is also possible to connect a multitude of additional devices, such as operating current trips, fault sensors and auxiliary sensors.
DLS 9
- UL 489
- are used for branch circuit protection
- provide the functions: overload protection, isolation, switching, short-circuit protection without back-up fuse (up to the nominal breaking capacity)
- approved for HACR applications
- extra-small nominal current increments for optimum installation protection: 23 nominal currents from 0.3 A to 63 A
- one of the smallest UL 489 miniature circuit-breakers with an installation height of just 105 mm
- DC product series: Provided that the polarity +/- is respected, current can be supplied at the top or the bottom
DLS 8
- UL 508
- act as supplementary protection
- extra-small nominal current increments for optimum installation protection: 27 nominal currents from 0.3 A to 60 A
- provide the functions: overload protection, isolation, switching, particularly in motor circuits
- smallest certified UL 508 switching device with an installation height of just 89.3 mm
- perfectly standardised installations thanks to combined IEC + UL approval
DLS 7
- UL 1077
- provide supplementary protection
- Intended for control current circuits
- as a component for installation in switching devices according to the UL 508A listing requirements
- from 0.5 to 60 amps
- provides the function: Overload protection
- UR certificate
