Description

1VCR004291G0005: Product Overview​

The ABB 1VCR004291G0005 is a specialized over-voltage coil accessory designed for ABB’s VD4 series medium voltage circuit breakers. As a critical component of VD4’s control and protection system, this coil monitors voltage levels in the circuit and triggers protective actions (e.g., tripping the breaker) when over-voltages occur. It also enables remote operation of the circuit breaker, making it essential for automated industrial and commercial power systems.
In medium voltage applications (typically 1kV–35kV), over-voltage events (caused by lightning, switching surges, or grid instability) can damage sensitive equipment or disrupt operations. The 1VCR004291G0005 coil acts as a first line of defense by continuously monitoring line voltage and initiating a trip signal to the VD4 breaker when thresholds are exceeded. This protects downstream devices (e.g., transformers, motors, and distribution panels) from catastrophic failure.
The coil is designed for seamless integration with VD4 circuit breakers, aligning with ABB’s modular approach to medium voltage systems. It works in conjunction with other VD4 accessories (e.g., under-voltage coils, auxiliary switches) to create a comprehensive control and protection solution.

Core Features & Customer Value​

  • Integrated Over-Voltage Protection: The coil continuously monitors line voltage, triggering an automatic trip if voltages exceed safe limits. This protects sensitive equipment (e.g., motors, transformers) from damage caused by transient over-voltages or grid anomalies. For example, in a manufacturing plant, a sudden voltage spike from a nearby lightning strike would be detected by the coil, which trips the VD4 breaker to isolate the fault—preventing costly downtime and equipment repair.
  • Remote Operation Enablement: The coil works with VD4’s remote control system, allowing operators to trip or close the breaker from a central control room. This is invaluable for applications where manual access to the breaker is hazardous (e.g., high-voltage substations) or impractical (e.g., large-scale distribution networks). For instance, in a utility company’s substation, operators can use the coil to remotely trip a VD4 breaker during a fault, reducing the risk of injury to field personnel.
  • Modular Design for Easy Maintenance: The coil is designed as a plug-and-play accessory, making it easy to replace or upgrade without disrupting the entire circuit breaker system. This reduces maintenance time and costs—for example, if the coil fails in a food and beverage plant, technicians can swap it out in minutes, minimizing production downtime.
  • Compatibility with VD4 Ecosystem: As a native ABB accessory, the 1VCR004291G0005 is fully compatible with VD4 circuit breakers and other ABB medium voltage products (e.g., switchgear, protection relays). This ensures seamless integration and consistent performance across the entire system, which is critical for large industrial plants or utility networks where reliability is paramount.

Typical Applications​

The ABB 1VCR004291G0005 is used in a wide range of medium voltage applications where over-voltage protection and remote control are essential:
  • Industrial Power Distribution: In manufacturing plants, the coil protects motors, transformers, and conveyor systems from over-voltages caused by starting large motors or grid fluctuations. For example, a steel mill uses VD4 breakers with the 1VCR004291G0005 coil to protect its rolling mill motors, which are prone to voltage spikes during startup.
  • Commercial Building Substations: In office buildings or shopping malls, the coil monitors voltage levels in the medium voltage distribution system, ensuring reliable power to elevators, HVAC systems, and lighting. If a fault occurs (e.g., a transformer failure), the coil trips the breaker to isolate the affected area, minimizing disruption to occupants.
  • Utility Substations: Utility companies use the 1VCR004291G0005 coil in their medium voltage substations to protect transformers and switchgear from over-voltages caused by lightning or grid switching. The remote operation feature allows operators to trip breakers from a central control room, reducing the need for field visits and improving response times during faults.
  • Renewable Energy Plants: In solar or wind farms, the coil protects inverters and medium voltage switchgear from over-voltages caused by fluctuating renewable energy output. For example, a wind farm uses VD4 breakers with the 1VCR004291G0005 coil to protect its transformer stations, ensuring stable power delivery to the grid.
