B200A-208V
The Model 200 3-Phase Voltage Unbalance Monitor, SKU B200A, provides essential protection for industrial equipment. Voltage unbalance can lead to motor overheating, reduced efficiency, and premature failure. This monitor precisely detects unbalance conditions, offering an adjustable range from 2% to 10%. Its rapid 100ms response time ensures quick detection, while the adjustable dropout time, from 0.2 to 20 seconds, allows for tailored system integration. With a robust DPDT 10 amp contact rating at 240VAC resistive, it reliably controls protective devices. The unit operates effectively across a wide temperature range of -20 to +131 F, ensuring consistent performance in diverse industrial environments. Its automatic reset type simplifies operation, minimizing downtime and maintenance requirements. This device contributes to extending equipment lifespan and maintaining operational continuity.
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.
