The Littelfuse models 111P (115 volt, ⅓ to 1hp); 233P-1.5 (230 volt, ⅓ to 1.5hp); and 233P (230 volt, ⅓ to 3hp) are single-phase pump monitors used in a variety of applications to protect from dry-well, dead-head, jammed impeller, rapid-cycling,...

The ARP Series is used in systems where equal run time for two motors is desirable. The selector switch allows selection of alternation of either load for continuous operation. LED’s indicate the status of the output relay. This versatile series may be...

The 350 series is a heavy-duty voltage monitor. This product should be used when high-current relays or dual contacts are required or when 480 V controls are used. Since the 350 series uses heavy-duty relays, it comes in fixed-voltage range models rather...
