The GE IC2800Y110D4 is a heavy-duty, time delay DC contactor with a massive 300A current rating and a 115 VDC coil. This robust device is designed for industrial applications that require sequenced switching of extremely high-power direct current electrical loads with a built-in time delay function.
Technical Breakdown
The core function of the IC2800Y110D4 is its integrated time delay capability. Unlike a standard contactor that operates instantaneously when its coil is energized, this model includes an integrated delay before its main contacts close or open. This feature is crucial for managing complex operational sequences, such as staggering the startup of multiple large motors to prevent massive inrush currents from overwhelming the power grid or allowing other processes to finish before a new one begins.
With its impressive 300A current rating, this contactor is built for the most demanding, high-power DC loads. This includes applications like large DC motors in rolling mills or mining equipment, high-capacity battery management systems, and other industrial systems where significant DC power needs to be switched reliably. The design for DC switching is specialized to handle the persistent arc that can occur, and this unit is built for that purpose.
The 115 VDC coil is another key feature, as DC control circuits are common in industrial facilities, especially those with backup power systems. This ensures the contactor can function reliably even during a power outage. Additionally, the contactor is equipped with a Normally Closed (NC) auxiliary contact. These low-current contacts are mechanically linked to the main contacts, serving a vital role in control circuit feedback, interlocking, and signaling.
Applications
The GE IC2800Y110D4 is a fundamental component in industrial control panels for:
- Heavy-Duty DC Motor Control: Providing a timed, high-current switching function for large DC motors in applications like cranes or rolling mills.
- High-Capacity Battery Management Systems: Safely connecting and disconnecting large battery banks in backup power or renewable energy systems.
- Emergency Systems: Ensuring backup systems or generators are brought online in a controlled, time-delayed manner after a main power failure.
- Industrial Automation: Serving as a reliable, high-current switching device in complex automated systems where timing and DC power are critical.
