M20-series Motor Protection

The M20-series is the baseline range in the Ningi Motor Protection Relay offering. Multi-functional motor protection and management relays – integrated protection, metering, monitoring, and automation functions.
Can be used on all motors — regardless of sizes, capacities, speed or torque.

M20-series relays offer flexible configuration, with 3-binary inputs and 4-voltage free relay contacts. The M20E has a non-volatile memory (retain memory in power down) to store events with date and time stamp. The M20E stores the last 16 events with date, time, three phase voltages, two phase currents, earth leakage reading, and event.

Fully configurable, includes relays for the detection and management of earth faults, phase failures, current failures and contact failures.
