High immunity to system interference by metallic isolation.
IKSK Frequency relays Cost-effective devices for small power stations. Remote control switches Specific installation devices Time switches. Manufacture of ceramic building materials. Temperature relays, thermistor motor protection relays The motor protection relay monitors the thermistors integrated in the motor. The measured frequency is compared with a frequency generated in the device and settable on a setting knob.

Dold Measuring Relays
Neutral monitors Protect loads against overvoltage and its consequential damages. As the phase angle changes with the motor load this measuring method is suited for monitoring asynchronous motors for underpower and no load operation independent of their size.
This frequency is compared with a frequency which is generated in the device and can be adjusted with a setting knob. If you continue we assume that you consent to receive cookies on all Deutsche Messe websites. Ensure the start ofthree-phase motors in the correct sense of rotation, e. If the speed-proportional frequency is higher than the reference frequency generated in the device, the output relay of the underspeed monitor will be energized and that of the overspeed monitor de-energized.
Using the reset function it is possible to cancel processes after a fault. The devices are used for voltage and frequency monitoring for decentralised in-house power generation systems. The products are equipped with differentfunctions depending on the application and compliance requirements.
