B259
The Model 259 3-Phase Monitor is designed to protect individual 3-phase equipment and motors, or in conjunction with shunt trip breakers. When correct voltage and phase rotation is applied, an internal DPDT relay energizes.A fault condition (phase loss, phase reversal, or low voltage) drops out the relay and lights the LED failure indicator. The Model 259 will detect a phase loss condition even when regenerative voltage is present.
The Model 259 may be used with Wye or Delta systems and requires no neutral connection. Standard operating ranges are available from 120 to 575 VAC, 60Hz and 380 VAC, 50Hz

B263
The Model 263 continuously monitors 3-phase power systems for phase loss, low voltage and phase reversal. The monitor consists of a solid-state sensing circuit, driving an electromechanical relay.Applying correct voltage and phase rotation energizes the relay.

When the fault is corrected, the Model 263 automatically resets. A manual reset version and an option for gold-plated contacts are also available.
The Model 263 does not require a neutral connection, and can be used on Wye or Delta systems. Each of the five different voltage ranges is adjustable to allow the monitor to be set for existing conditions. NORMAL and TRIP LED indicators are provided to aid in adjustment and system troubleshooting.

B2638
The Model 2638 3-Phase Monitor combines a 3-phase monitor with a line voltage and phase sequence indicator. Like other Time Mark Monitors, the Model 2638 senses phase loss, phase reversal and low voltage.When power and phasing are correct, the internal relay energizes. LED indicators will show that all phases are present, and the direction of phase rotation.
When a fault occurs, the monitor trips its relay and indicates which phase is lost, or, if a reversal is present. This allows you to automatically protect your equipment by correcting the appropriate fault condition.
The Model 2638 will automatically reset when correct power is restored. It is available in 208/240 VAC, 480 VAC, or 380 VAC/50 Hz.

B2642
The Model 2642 protects electrical equipment by sensing phase loss, low voltage and reverse phase conditions. The monitor uses a combination of voltage and phase-angle sensing, and will detect a phase loss even when regenerated voltages are present.The Model 2642 is fail safe; the output contacts will transfer when correct power is applied, and trip out on any fault condition or complete loss of power. Each of the five voltage versions can be adjusted throughout a wide operating range. An adjustable trip delay timer prevents nuisance tripping caused by momentary voltage dips. LED indicators show NORMAL (green) and TRIP (red) status.
The Model 2642 has an automatic reset which can be converted to manual reset with the addition of a normally closed switch. The DPDT out put can be used in motor control circuits and/or alarm circuits.

B2644
The Model 2644 3-Phase Monitor continuously monitors 3-phase Wye or Delta systems for abnormal conditions.The solid-state electronic sensing circuitry drives an internal DPDT relay, allowing the Model 2644 to operate two motor control circuits, or a control circuit and an alarm circuit. An adjustable trip delay reduces or eliminates nuisance tripping caused by momentary voltage fluctuations on motor start-up. An optional restart delay gives approximately a 3.5-minute delay when the relay drops out, to allow compressor head pressures to bleed off, in the event of short-term power failures.
Voltage adjustment ranges are sufficiently wide to allow for proper calibration to existing conditions. Both TRIP and NORM indicators are provided to aid in adjustment and system troubleshooting. Automatic and manual reset versions are available. The Model 2644 Monitor is not sensitive to line current, and can be used with any size motor or compressor.

C200
The Model 200 3-Phase Voltage Unbalance Monitor is designed to continuously monitor a three-phase line for unbalanced voltage conditions.This device will only energize the relay if an unbalance exists. Zero volts on all three phases is considered a balanced condition. This allows the Model 200 to be used with shunt breakers, so that the breaker can shut off the main power without tripping the monitor.
The solid-state sensing circuit drives an internal electromechanical relay. Indicator lights on the monitor show when the voltage balance is within an acceptable range; when an unbalance exists; and when the relay is actually tripped.
When an acceptable voltage balance is reapplied, the Model 200 will automatically reset the relay.
