The class II Model 610 Digital Current Monitor offers the latest technology for providing positive and accurate over current motor (load) protection for single, and 3 phase motors, drawing between 5 and 200 amps. The Model 610 also can monitor up to two thermistor temperature sensors to detect abnormally high and/or low compressor operating temperatures. Motor protection is accomplished by monitoring the operating motor current, in each phase of the load, using current transformers. For both single and 3 phase loads, the control digitally processes the sampled current and calculates the excess energy being absorbed by the motor due to current flow above the operator selected trip level. If the current is above the selected trip level, the controller calculates the excess power and integrates to calculate excess energy. When the excess energy rises to a level equivalent to locked rotor for 2 seconds, a current trip will occur. If the current drops below the trip level prior to a trip, the controller will reset the integration to zero. This prevents false-alarm trips. Fail-safe operation is provided by protecting the load from excessive current or abnormal temperatures in one or more of the following overload conditions:
If one of the above conditions occurs, the Model 610 operates a TRIP relay to disconnect power from the load. An ALARM relay is also provided that can be used to alert operators of a lockout condition. The number of automatic trip resets allowed before a lockout occurs is operator selectable. The automatic trip reset time is also selectable. When protecting 3 phase loads, the Model 610 detects phase
imbalance and can also verify correct phase rotation during each load's startup. Setting the current trip level at 8% above the nominal FLA of the motor will indirectly provide both low and high voltage protection. Setting the current trip level at other percentage levels above FLA will directly protect the motor. The optional, customer supplied, Omega 10K thermistor temperature sensors can be used to monitor compressor exhaust temperature and crankcase oil temperature. Omega offers a wide range of thermistor sensors that are readily available. The trip temperature values are operator selectable. The Exhaust high temperature value can be set between 80°F and 300°F or between 100 Ohms and 20K Ohms. The Oil temperature trip values can be set for high, low or both high and low trip temperatures between 20°F and 200°F or between 200 Ohms and 20K Ohms. Consult factory for different temperature ranges.

Littelfuse 250A VAC age/Phase Monitor Relay, 190 - 480 VAC , DPDT, 4 sec The 250A is a 3-phase, auto-ranging, dual-range VAC age monitor that protects 190 - 480 VAC , 50/60 Hz motors regardless of size from low and high VAC age, unbalance/single-phase and reverse phase. The product provides a user selectable nominal VAC age setpoint and the VAC age monitor automatically selects between the 200 VAC and 400 VAC range. The 250A also features adjustable or manual restart delay. This unique microcontroller-based VAC age and phase-sensing device constantly monitors the 3-phase VAC ages to detect harmful power line conditions. When a harmful condition is detected, the output relay is deactivated after a specified trip delay. The output relay reactivates after power line conditions return to acceptable levels. The model 250A includes advanced single LED diagnostics. Five different light patterns distinguish between faults and normal conditions.,
