Littelfuse current and load monitoring relays, sensors, and transducers are the ideal solution for monitoring loads. These products protect against equipment damage from irregularities and predict risks before they cause problems. They monitor input and output currents passing through circuits for warning signs such as overvoltage or undervoltage, overcurrent or undercurrent, phase issues, and other indicators. Each protective unit provides an applicable response. Littelfuse offers single-phase current monitors, load sensors/relays, current transducers, current sensors, and accessories for remote monitoring.
