Selection and system combinations
Dual-circuit energy control combines switching with power measurements. Compare ER1 for single-circuit 4G energy control and branch acquisition products for additional metering circuits.
Related product comparisonChoose an energy relay when one circuit needs both 4G switching and power data. Compare a switching-only controller for simple start/stop duties, or a multi-circuit energy controller for additional circuits.
