The motor protection relay monitors the thermistors integrated in the motor.
Dold rp9800 pdf
Wholesale, except for motor vehicles and motorcycles. Compared to voltage relays they have the advantage that they respond in the case of a system phase failure, even if the missing system phase is generated and recovered by the motor. Hydraulics, pneumatics and sealing technology. Undervoltage and overvoltage relays, voltage monitors,single- and three-phase: Measuring relays for power generation systems. ILSL 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.
BAAI N. Protect against overflow and dry-running, e. Check for overload due to blocking, sluggishness, tool wearing, clogging, etc. Output contacts Module translation not found: Voltage and frequency monitor. Very sensitive measuring for underpower, far better than it would be possible with pure current measuring. Measuring relays Home Advantages Technology Applications Product selection DOLD measuring devices reliably monitor electrical quantities such as current, voltage, power, resistance etc.
Choice of two outputs for min. Temperature relays, thermistor motor protection relays The motor protection relay monitors the thermistors integrated in the motor. Measuring technology and testing technology for automation. Monitor the current flow in single- and three-phase systems, e.
Relay Modules Safety Devices. System monitoring when power is fed in the system,e. As electrical machines partly regenerate such a missing system phase only an unbalance relay can detect such a case. Please select required language: Complete fp9800 protection for overvoltage and undervoltage monitoring within a single compact product e. Unbalance relays monitor the system for phase failure and are mainly used to protect motive-power loads. Reliable protection of rp98000 and devices with a minimum of investment.
Original formed parts casting, sintering. Comply with specific norms, e. Avoid risks to man and machinery, e.
Dold Measuring Relays
Electricity generation from wind energy. Measuring relay for specfic applications Special-purpose applications, e. ILphase relay with thermistor motor protection: Phase-sequence relays check the system for clockwise phase sequence and prevent motors from starting in the wrong sense of rotation.
Current and temperarure monitoring f. Temperature relays, thermistor motor protection relays Use in pumps, fans, ball bearings, for example. Operate delay Module translation not found: Load isolator with interlock. Some application examples odld the differentdevice groups are mentioned below: Monitor machines for a too long or too dolx work cycle.
