The GE part number IC9033C5C5 is a Resistor Assembly. It’s a component of GE’s legacy Directo-Matic control systems. Its primary function is to provide a specific electrical resistance for various control or protective functions within the system. 🔌
Function and Features
A resistor is a passive electrical component that limits or regulates the flow of electrical current. The “RES” in the part number indicates it is a resistor, while the other numbers provide specific characteristics:
- Resistance (1.20 Ohms): This is the value of electrical resistance that the component provides. This resistance is crucial for limiting current in a circuit, such as in a motor control or power regulation application.
- Current Rating (32A): The “32A” indicates that the resistor is designed to safely handle a maximum current of 32 Amperes. This is a key safety specification, as exceeding this limit could cause the resistor to overheat and fail.
- No Taps: The “no taps” designation means the resistor has a single, fixed resistance value. Resistors with “taps” have multiple connection points, allowing for different resistance values to be selected. The absence of taps means this is a simple, fixed-value component.
- Assembly: The term “Assembly” indicates that this is more than just a single resistor. It’s a pre-packaged unit that includes the resistor and its mounting hardware, simplifying installation in the field.
- Robust Design: Like other GE industrial control products of its era, it was built to withstand the harsh conditions of a factory floor, including electrical noise, vibration, and temperature fluctuations.
Applications
The IC9033C5C5 is a legacy component primarily found in older industrial plants and facilities that still operate GE’s Directo-Matic systems. It’s used in:
- Motor Control: Limiting the starting current of a motor.
- Power Regulation: Acting as a load or a current-limiting device in a power supply circuit.
