TERASAKI ARU-1DC New - Surplus AR Series UVT Control

Product Overview

The Terasaki ARU-1DC is a specialized Under Voltage Trip (UVT) Control Power Supply Unit designed for use with the TemPower 2 (AR Series) Air Circuit Breakers (ACBs). This unit serves as the interface between the control power source and the UVT coil within the breaker. It ensures that the ACB trips safely if the monitored voltage drops below a predetermined threshold, protecting downstream equipment from brownouts or phase failures. As a New - Surplus item, it provides factory-level reliability for critical power distribution and switchgear maintenance.

Key Features

• TemPower 2 Integration: Purpose-built for seamless compatibility with Terasaki’s AR series ACBs.
• Stable Trip Control: Provides the necessary rectified and regulated power to the UVT coil to prevent "nuisance tripping" while ensuring rapid response during actual voltage drops.
• Compact DIN/Internal Mount: Designed for space-efficient installation within the circuit breaker enclosure or control compartment.
• Critical Safety Function: Facilitates the mandatory safety shutdown of the breaker during loss of control power or under-voltage conditions.
• Industrial Build Quality: High-grade internal components designed for the long service life typical of heavy-duty switchgear.

Item Condition (New - Surplus)

• Functional Status: New/Unused. This unit is surplus stock that has never been installed or energized. It is in perfect working order.
• Physical State: Pristine. The housing, connection terminals, and mounting points show no signs of use or wear.
• Visual Reference: Please refer to the high-resolution images to verify the specific input voltage rating (e.g., 100-120V AC/DC or 200-240V AC/DC) on the nameplate; the unit pictured is the exact ARU-1DC you will receive.
• Note: As a surplus item, the original Terasaki box may show minor shelf wear or storage markings, but the device itself is factory-new.
