Feature of CSMPM Digital Motor Protection Relay
- Digital Relay with built-in MCU (Micro Processor Control Unit).
- Multiple protection: Overload / Phase failure / Stall /Asymmetry / Phase reverse/ Earth Fault.
- Current setting 0.5-6A & 5-60A.
- Current setting 0.5-6A can be used up to 600A with external Ct’s
- Fault diagnostic seven-segment display of fault & values.
- Digital Ammeter function.
- Time setting: Inverse time (0-60 sec), Definite time (0-60 sec) starting & Delay time (0-30
sec) operating time. - Accuracy: Current / Time + 5% of setting.
- Fail-safe operation
- Alert function (60-110% of set current).
- Inverse / Definite time characteristics, site selectable.
- C.T. ratio setting in CSMPM-06 frame only.
