EMR4/EMR5 Measuring and Monitoring Relays

Measuring and monitoring relays are required for various applications in electrical switchgear technology.

EMR4/EMR5 range measuring and monitoring relays cover a wide range of applications: Current monitors for universal use, phase monitors for monitoring destruction/damage protection for individual system sections, phase sequence relays monitoring the rotating field, unbalance relays for reliable phase loss detection, multifunctional three-phase monitors, asymmetric phase monitoring relays in a single device, level monitoring relays for monitoring fill levels and earthleakage monitors for enhanced operational safety.

All relays are devices for world markets to IEC/EN 60947 and UL/CSA approval.

Many relays feature multi-voltage coils. This simplifies stock keeping and enhances the flexibility when reacting to customer requirements.

Note: We have partly updated our range of measuring and monitoring relays. Some EMR4 relays have been replaced by equivalent EMR5 types.
