Monitoring relay
120 - 240 VAC | PGM-8325 series Littelfuse

Monitors are single function devices that only look at one abnormal condition and either alarm or provide a means to remove power. Visual indication can also be used. The purpose of a monitor is to provide a low-cost solution to a dedicated problem. Monitors are typically added to existing protection, such as fuses, circuit breakers, or protection relays.
