3-PHASE VOLTAGE MONITOR/ 190-4

Surge protective devices (SPDs) provide equipment protection from transient overvoltage events lasting microseconds. By limiting the overvoltage to the equipment during these events, costly damage...

The SPD2 1P+0 series is a surge protection device that safeguards components from transient overvoltage or surges that last micro-seconds by limiting the fault current to a load or the unit being...

UL CLASS T FAST-ACTING FUSE

The TDMB combines both delay-on-make and delay-on-break functions into one plug-in package. Selection of the time period is accomplished with dual switches, one for the on delay and the other for the...

The SE-134C/SE-135 is a microprocessor-based, combination ground-wire monitor and ground-fault relay for resistance grounded or solidly grounded systems. It continuously monitors the integrity of the...

The SE-105/SE-107 is a combination ground-wire monitor and ground-fault relay for resistance-grounded systems. It continuously monitors the integrity of the ground conductor to protect portable...

The MP8000 series motor protection relay is designed to protect three-phase or single-phase motors with operating voltages of 90-690 V ac (use of external potential transformers can extend upper...

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 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...
