MH EF18 DTL Earth Fault Relay
The Earth Fault Relay EF18 is designed to monitor power system and provides a relay operation in the event of an earth fault situation. The EF18 relay incorporates the MTB fault indication system in advanced protection relaying for system abnormalities. This eliminates the need of an auxiliary supply to provide a fault indication, ensuring enhanced safety.

Mechanical Trip Button (MTB) fault indication system

No requirement for auxiliary power supply for fault indication

Safeguard against automatic reset before fault rectification

Tamper-proof design for setting protection

Type tested for EMC compliance in accordance with IEC 61000

High immunity to electrical interference (tested to 2.5GHz)
