Earth fault definite time residual current relay with 1 alarm threshold and 1 operation delayed threshold. Thanks to the warning threshold alarm, the relay is suitable for those plants where preserving service continuity or minimizing the risk of equipment damage is the more important objective. The device is supplied in a 4 modules case for standard DIN rail mounting with a sealable transparent plastic cover in order to prevent infringements to the settings.
Options:

• Mechanical flag indication for relay tips: type RMT/4DM
• 3...300A setting range: type RMT/4DB
