## Summary description

Karlik 28DWPUS-33 is a level switch in graphite finish designed for monitoring liquid levels. It features IP20 protection, AC input voltage 250 V and a nominal output current of 10 A. Suitable for integration into control panels and building installations where a compact, switch-type level sensor with standard mains compatibility is required.

## Long description

Karlik 28DWPUS-33 is a compact level switch in a graphite finish designed to detect and report liquid levels for integration into control panels and building installations. The device accepts AC mains voltage up to 250 V and provides a switching contact rated for a nominal output current of 10 A. Its IP20 protection level makes it suitable for indoor installation in electrical enclosures and distribution boards where a small, switch-type level sensor with standard mains compatibility is required.
Advantages
The switch combines a compact form factor with a standard mains-rated switching capacity, enabling straightforward replacement or addition to existing control systems. Graphite finish offers a neutral appearance for visible panel mounts. IP20 protection simplifies installation inside cabinets while ensuring protection against solid objects. The unit’s nominal 10 A output current supports direct control of many common loads and relays when used within rated limits.
Suitable for
Level monitoring in indoor control panels
Integration into building automation and pump control systems
Signal input for relay logic and control circuits
Retrofit applications where space is limited
Key specifications
Operating voltage: AC 250 V
Nominal switching current: 10 A
Protection rating: IP20 (indoor use, protected against solid objects \>12 mm)
Finish: graphite
Compact switch-type form factor suitable for panel mounting
How to use
Mount the level switch inside an appropriate electrical enclosure or control panel in a location that allows the sensing element or actuator to interact with the monitored system. Connect the AC supply and load to the switch using conductors and terminals rated for AC 250 V and the nominal switching current. Ensure wiring follows local electrical codes and that the device is installed by a qualified electrician. Verify correct operation by simulating the liquid level change or using the system’s test mode.
Usage recommendations
Do not use the unit outdoors or where it will be exposed to water spray or direct contact, since the IP20 rating provides protection only for indoor, enclosed installations. The listed light modules (L-1, L-2, 2L-2, 3L-2, 17L-2) are not compatible with this switch. Always confirm that connected loads and control devices do not exceed the 10 A nominal switching current and that proper overload protection is provided.
