ABB 1VCF309499S0012 Control Module Feeder AU-TR 100-250VDC/AC

ABB 1VCF309499S0012 Control Module Feeder AU-TR (750203/806)

ABB 1VCF309499S0012 is a high-performance industrial and marine grade Control Module Feeder (Type AU-TR) that provides reliable auxiliary power management for medium-voltage vacuum contactors. Designed for smooth integration with ABB’s V/Contact and V/ZVC product series, this vital control module provides reliable, uninterruptible voltage supply throughout a wide, highly flexible 100-250V AC/DC auxiliary range.

Whether used in demanding shore-based distribution plants or severe maritime situations, the 1VCF309499S0012 is the backbone of electrical latching and switching control. Designed to withstand the rigours of frequent cycling, temperature swings and high vibration stress in naval engine rooms, switchboard cubicles and heavy industrial automation racks. This unit is the approved improved manufacturer replacement to the legacy 1VCF309499R0012 type, with improved heat dissipation and revised electrical latching configurations.

Key Features

1. Wide Voltage Range Adaptation: Can adapt to input fluctuations of AC and DC currents from 100V to 250V.
2. The included electrical latching system includes logic control to ensure the consistent retention of contact states without continuous power consumption.
3. Marine-Grade Resilience: Built to endure structural harmonic vibrations and localised electromagnetic interference (EMI) to meet the rigours quality standards.
4. Direct Legacy Replacement: By means of drop-in compatibility, obsolete engineering versions are replaced without the requirement for rewiring or mechanical adjustments.
5. Compact, Lightweight Design: At just 0.78 kg this unit optimises the space available in packed low and medium voltage maritime starting panels.

Compatibility

This module is explicitly certified for use within the following medium voltage hardware subsystems:

• ABB V/Contact Series Vacuum Contactors
• ABB V/ZVC Compact Switchgear Control Modules

Cross-Reference Part Numbers

To ensure matching engineering data sheet records across diverse global supply chains, this asset maps directly to:

• ABB 1VCF309499R0012 (Legacy Predecessor)
• ABB 750203/806 (Internal Assembly / DIP-Switch Reference)
• 750203806

Installation Checklist:

Warning from the Engine Room: Before extracting an old 1VCF309499R0012 or installing this updated S0012 module, isolate the main breaker and double-check that the auxiliary power lines are dead. Residual voltage on the 100-250V line can instantly blow the internal optocouplers of new control units.

Engineer’s Guide:

1. DIP-Switch Calibration: Pay attention to the factory DIP-switches on the side of the 750203/806 module framework. Match these layout settings exactly to your vessel’s existing breaker configuration sheet. Incorrect switch configurations will lead to immediate latching logic faults or unexpected trip signals during startup sequencing.
2. Thermal Monitoring: While this feeder handles up to 250V AC/DC seamlessly, high ambient temperatures within sealed marine motor control centers (MCC) accelerate capacitor wear. Ensure that switchgear cabinet fans and filter elements are free of salt-crust and oil mist to prolong the component’s operational life.
