The Eaton family of general purpose relays includes the Type AA, power and plug-in relays including the D2, D3, D4, D5, D7, D8, and D9 series relays. These general purpose relays provide a compact design that can be panel or DIN rail mounted. (read more)

Voltage Monitoring Relays by Eaton Corporation protect distribution systems suppplying motor feeder or branch circuits against premature equipment failure caused by voltage faults on three-phase systems. (read more)

The extensive range of true power monitors is used to provide an indirect measurement of physical values, i.e. it is simple to use the true power to draw conclusions about values such as volume, levels or pressure. This economical solution requires no additional sensors. (read more)

Carlo Gavazzi has expanded the SOLITRON Series with the addition of the RJCS Series Current Monitoring Solid State Relay . (read more)

The Model 2744 3-Phase Over Current Monitor is designed to monitor the current level of a three-phase line or to compare the currents of three single-phase lines.

If one or more current inputs rises above the trip level after the start delay has expired, the internal relay will de-energize.

Start delay of 5 to 15 seconds and adjustable trip point from 1 to 5 amps. (read more)

Current Sensing Relays provide an effective and highly stable method for monitoring electrical current. Current Transducers and Transmitters are for AC or DC Voltage & Current Voltage, Current, Power, Power Factor, Energy and Frequency can all be monitored in a single package. The sensed information is then provided to the system via an RS485 serial bus. (read more)

SPDT Relay, 40 amps: HAT 900 Series switches is 40 amps open and 30 amps closed while nearly all other brands do 30 amps open and 20 amps closed. Coil voltage is both AC and DC! Relays are produced in Hasco's own factory www.hascorelays.com (read more)

Carlo Gavazzi has expanded their already comprehensive range of three-phase monitoring relays to include the DPB71 and the DPC Series. These are three phase devices which are ideal for protecting machinery and people in instances where three phase voltage is used, such as with industrial automation machinery, switchgear and elevators/escalators.

The DPB71 Series is constructed i... (read more)

DIB01CM Series, a new current monitoring relay with an 8 amp Form C contact output. The built-in current transformer, with 12mm through-hole, provides a means to save panel space and reduce wiring time, thus minimizing the total cost, space and connection time. (read more)
