Power relay EISH

Phase fault relay CM-PBE

Phase fault relay CM-PBE

Art. no.: 3860595

The CM-X series consists of relays for monitoring 1-phase voltage and current, 3-phase monitoring (over / undervoltage, phase sequence, phase error, phase imbalance, frequency), insulation, motor load, thermistor, temperature, fluid levels, cycles and contact protection. The series is available in 3 different enclosure types (E, S and N) and with options for screw or screwless connection to the terminals. All settings are available on the front of the products and can thus be made easily after assembly.

Phase fault relay CM-PBE

Monitoring of phase sequence and phase failure control relay 3-phase

Monitoring of phase sequence and phase failure control relay 3-phase

Art. no.: 3864690

Functional description
The relay monitors that all three phases are live, and that the phase sequence is correct. The relay is on as long as these conditions are met. When monitoring engines, the relay falls when one of the phase-phase voltages is less than 85% of the other phase-phase voltages.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays

Monitoring of phase sequence and phase failure control relay 3-phase

Monitoring of phase sequence and phase failure control relay 3-phase

Control relay RM17/35

Schneider Electric

Control relay RM17/35

Art. no.: 3880396

Relays for measuring over or under current within a range from 2mA to 20A.

Control relay RM17/35

Control relay RM17/35

Load guard, power monitor BVN

Eldon Installation

Load guard, power monitor BVN

Art. no.: 3886032

Load switch for monitoring of 3 phases. With BVN one can lower the main fuse from e,g, 20 A to 16 A and thus obtain a lower fuse rate. BVN controls one or more groups which can be disconnected for short periods. One can e.g. choose to temporarily disconnect the water heater, electric cartridge or a number of electric radiators. BVN is intended to be mounted in standard central or as a separate unit for existing plants. BVN is also available as a complete unit including current transformers, enclosure and with contactor.

Monitoring relay RM17/35 3-phase

Schneider Electric

Monitoring relay RM17/35 3-phase

Art. no.: 3880370

Relays that can monitor phase presence, phase direction, asymmetry, under and over-voltage in three-phase systems.

Monitoring relay RM17/35 3-phase

Monitoring relay RM17/35 3-phase

Voltage measurement relay 3-phase for over and under voltage

Voltage measurement relay 3-phase for over and under voltage

Art. no.: 3864692

3-phase monitoring relays for phase sequence/Phase break and Over-/Under Voltage for mounting on DIN rails or 11-pin base.
Functional description
The relay is pulled when the phases or the phases + 0 are within the set limits, the relay falls if the limit values are passed after the set time delay (0.1-30s). The relay also monitors phase breaks and phase sequence, at the wrong phase sequence or phase break the relay falls without time delay.
All relevant data, as well as the circuit diagram are clearly marked on the side of the relays.3 LEDs. Green lights up when the control voltage is connected. Yellow lights up when the relay is on and Red flashes during the time, and is lit with a steady light in alarm.

Monitoring relay MIC

Monitoring relay MIC

Art. no.: 3862157

Current relay MIC (2A-20A. Over/under current with integrated transformer). For checking overcurrent in AC networks via internal current transformer. The product requires operating voltage. The current conductor is pulled through the hole in the relay (current transformer) for measuring the AC current. The current transformer hole is 10mm. The MIC relay controls overcurrents. The relay pulls (closes) when the current exceeds the limit value shown on the front and drops (opens) when the current drops below the limit value. Operating voltage 24-240 V AC/DC.
