Overview
The Pfannenberg 460V 3 Phase Monitor Relay (SKU: 18883000015) is a DIN-rail mounted device designed to monitor 3-phase electrical systems for critical voltage faults. Rated at 460V AC, it detects overvoltage, undervoltage, phase loss, and phase imbalance to protect industrial equipment from damage. This relay is ideal for manufacturing plants, power distribution systems, and automation applications where reliable voltage monitoring is essential. Built for heavy-duty environments, it ensures continuous operation by alerting operators to potential issues before they escalate. Manufactured in Germany by Pfannenberg, a specialist in industrial monitoring solutions, this relay meets stringent quality standards for durability and performance.

455
The 455 Series are 3-phase voltage monitors that combine load and line side monitoring to offer complete protection. Monitoring the load side will alert the user of contactor failure or impending contactor failure. Line side monitoring will also protect the motor from damaging fault conditions that may be present prior to the motor starting. With other line/load side monitors, the motor must be started before a voltage fault is detected. With the 455, your motor is fully protected at all times. The 455 Series are 3-phase, dual range voltage monitors that protect 190-480VAC, 50*/60Hz motors, regardless of their size. It automatically selects between the 200V and 400V range when the user selects the nominal voltage setpoint. Other adjustments include a 2-30 second trip delay, a 2-300 second restart delay (and manual restart) and a voltage unbalance trip point of 2-8%. The voltage monitor’s circuitry is powered through the line side connections, so there is no need for separate control power, making it easy to install. Equipped with an infrared LED, the 455 Sereies can communicate to the optional hand-held diagnostic tool, Informer-MS to obtain valuable information such as real-time voltage, voltage unbalance on both line and load sides, motor run hours, last 20 faults, last 32 motor starts, high and low voltage trip points, voltage unbalance trip point, restart and trip delay settings, LED status and more.
