The FLSR series dual-element, time-delay UL Class RK5 fuses are the most widely used fuse class. They offer superior performance and excellent protection for all types of circuits, especially those with motors. Precision manufactured parts ensure an...

The PLMU11 continuously measures the voltage of each of the three phases to provide protection for 3-phase motors and sensitive loads. Its microcontroller senses under and overvoltage, voltage unbalance, phase loss, and phase reversal. Protection is...

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...

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 for 3-phase, 200-480 V ac applications, with several...

The 102A series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190–600 V ac, 50*/60 Hz motors regardless of size. This monitor provides a user-selectable nominal voltage setpoint and will automatically select between the 200 V...

The 202 series is a three-phase, auto-ranging, dual-range voltage monitor that protects 190–480 V ac, 50*/60 Hz motors regardless of size. The 202-RP (and the 202-575-RP for 475–600 V ac) monitors the phase rotation of the three-phase systems and trips...

The TS1 Series offers proven reliability and performance with years of use in OEM equipment and commercial applications. This encapsulated general use timing module is capable of controlling load currents ranging from 5mA to 1A. May be connected in...

Detects phase current or ground-fault current. (200-A primary)

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 relay can operate in the fail-safe or non-fail-safe...

The PGA-LS10 series arc-detection point sensors are capable of detecting light from every angle in front of them due to the shape of the cylindrical lens on the front of the sensor. These sensors are installed and positioned in switchboards to give them...

The 102A is a 3-phase, auto-ranging, dual-range voltage monitor that protects 190-400VAC, 50/60Hz motors regardless of size. The product provides a user selectable nominal voltage setpoint and the voltage monitor automatically selects between the 200V...

The LSR-0 is a self-powered load sensor intended for use as a proof relay. It is used to verify that current is flowing as intended. It has a guaranteed 15A pull-in current and 2.5A drop-out current. Proof relays are typically used to interlock fans,...

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

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 communication port and mount the push-button switch in a convenient...
