Littelfuse 460 3-PHASE VOLT MON/ 190-480V/ AD

3-PHASE VOLT MON/ 190-480V/ AD

The Littelfuse 460 is a 3-Phase Volt Monitor/Alarm for use with any Lenel(R) Building Access Control System. The Volt Monitor has power monitoring capabilities and can be set to issue an alarm when voltage drops below or rises above a user-selectable threshold. It can operate with 3-phase 190-480 VAC current or from 120 VAC. A relay contact on the front panel permits remote sound and/or visual indicators to be connected.

A complete solution for on-site power management and monitoring. The Littelfuse 460 3-Phase Volt Monitor is an economical, single, high accuracy 3-Phase Voltage Monitor that offers 600V CAT III isolation protection with an industry leading survey time of less than 0.7 seconds and VFD protection out to 2,000 A. This robust instrument yields fast accurate results which are displayed in a user friendly graphic LCD display with built in printer support and optional data logging capability.

Littelfuse 460 Series 3-Phase volt meters are designed to quickly and accurately measure on 240 Vac, 3-phase AC voltages or currents. The meter features a wide operating range (190-480 VAC), with 0.25% full scale sensitivity.

The Littelfuse 3-Phase Volt Monitor is specified for 3-phase systems, and specifically designed to monitor both the neutral and the line conductors of a high voltage electrical service. The unit provides monitoring and protection of both the line (hot) and neutral conductors at one location via two operators. The operator will trip when either one of these critical voltages falls outside the set range.

The Littelfuse 460 series three-phase voltmeter with current measurement will help protect multimillion-dollar production lines and large infrastructure projects from voltage and current imbalances that can cause equipment failure, safety risks, and outages. With a current range of 0 to 5400 amps (480A) at 480VAC/230VAC, plus optional monitoring for other configurations up to 25 kA at 660VAC, the 460 series offers unparalleled measurement precision at true utility power levels.

Utilizing their expertise in surge protection and EMC snubbers, Littelfuse has expanded its product line toward monitoring solutions for excessive high voltage conditions and power quality disturbances. The 460 is a single-phase/3-wire volt monitor providing protection against overvoltages, ground faults, and reverse polarization. The 460 series is intended for use on supply circuits up to 480 VAC or 500 VDC. The circuit of the device does not depend on voltage level; however it is advantageous

**Monitoring a three-phase system is vital for assuring optimal operation of the electrical system. Monitoring the power to the building by using a multimeter and visual inspection will alert the technicians to possible problems before they cause major damage**. This meter is non-invasive, and will monitor three-phase voltages without requiring access to live power. When coupled with real time trending and graphing software, this device provides technicians with a quick and easy tool for trending and managing data.
