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...

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...

The 460 Series Slo-Blo® SMF is based on Littelfuse PICO® fuse through-hole technology, though offered in a surface mount package.

The 460 series is a three-phase voltage monitor that protects 190–480 V ac or 475–600 V ac, 50/60 Hz motors regardless of their size. This voltage monitor provides a user-selectable nominal voltage...

The 777 unit is a fully-programmable, electronic overload relay designed to protect any motor drawing 2-800 full load A (external CTs are required above 90 A). The 777 (family of products) is used...

The 777 Manual Remote Reset Kit allows the 777 line of motor and pump protection products to be manually reset without opening the panel door. Simply connect the 9-pin adapter to the 777...

The SE-701 is a microprocessor-based ground-fault monitor for resistance-grounded and solidly grounded systems. It is uniquely suited for use on systems with significant harmonic content. Its output...

Littelfuse® offers a selection of E- and R-rated medium voltage fuses for the protection of transformers, potential transformers, feeders, and motor circuits. Single, double, and triple barrel...

The ALT series alternating relays are used to alternate between two loads. The ALT is commonly used in duplex pumping applications to balance the runtime of both pumps. The ALT-S is used in single...

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...
