The LSRX/LSRX-C Series are AC current sensors designed to energize the output contact whenever 4.5 Amps or greater is present. The LSRX/LSRX-C Series is used commonly as an AC current proof relay to...

The ALT Pump Controls series is used to alternate between two loads and is commonly used in duplex pump-up and pump-down applications to balance the run-time of both pumps. The ALT relays have a...

The ALT 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 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...

JTD600ID is a Class J fuse with an ampere rating of 600 and knife-blade-style construction. Ampere Rating (A) 600 VAC (V) 600 VDC (V) 500 Interrupting Rating 20 kA @ 500...

JTD350ID is a Class J fuse with an ampere rating of 350 and knife-blade-style construction. Ampere Rating (A) 350 VAC (V) 600 VDC (V) 500 Interrupting Rating 20 kA @ 500...

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...

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...
