The GE IC2800A501AB24C is a heavy-duty, time delay contactor with a 100A current rating. It is distinguished by its 230 VDC coil and built-in time delay function, which is essential for sequenced control of high-power electrical loads.
Technical Breakdown 🧠
This industrial-grade contactor is designed for demanding applications where precise timing is required.
The core function of the IC2800A501AB24C is its time delay capability. Unlike a standard contactor that operates instantly when its coil is energized, this model introduces a programmable or fixed delay before its main contacts close or open. This is critical for sequencing complex operations, such as staggering the start-up of multiple motors to prevent a massive inrush current from overloading the power system.
The 100A rating signifies its role in controlling large electrical loads, like motors, heating systems, or lighting banks, in heavy industrial settings. The 230 VDC coil is another key feature, as DC control circuits are prevalent in many industrial plants, often powered by reliable battery backup systems. This ensures that the contactor can be operated even during a power outage.
Additionally, the contactor includes multiple auxiliary contacts (1 Normally Closed and a combination of 1 Normally Open and 1 Normally Closed). These low-current contacts are mechanically linked to the main contacts and are used for feedback, interlocking, and signaling within the control circuit.
Applications 🏭
The GE IC2800A501AB24C is a fundamental component in industrial control panels for:
- Motor Sequencing: Staggering the start of multiple motors in a factory to manage power demand.
- Process Timing: Providing a time-delayed switching function in a manufacturing process, such as for activating a secondary pump after a specific interval.
- Emergency Systems: Ensuring that 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 is critical.
