Description
Product Name: CR306E0**LVH GE Power module
Product details:
The GE CR306E is a heavy-duty, NEMA Size 3 magnetic motor starter designed for full-voltage, non-reversing (FVNR) starting and stopping of AC squirrel-cage motors. It integrates a magnetic contactor with a thermal overload relay to provide robust control and essential overcurrent protection for industrial motor applications.
Known for its reliability in harsh environments, it features long-lasting silver-cadmium oxide contacts and an encapsulated coil to resist moisture and mechanical shock.
2. Technical Parameters (Typical Specifications)
Because specific suffixes dictate exact coil voltages and enclosure types, the standard specifications for a NEMA Size 3 (CR306E) starter include:
| Parameter | Specification |
| Manufacturer | ABB / General Electric (GE Industrial Solutions) |
| Series | CR306 (NEMA Rated Magnetic Starter) |
| NEMA Size | Size 3 |
| Number of Poles | 3-Pole (3-Phase operation) |
| Continuous Ampere Rating | 90 Amps |
| Maximum Horsepower (HP) | 30 HP @ 200V
34 HP @ 230V 50 HP @ 460V/575V |
| Phase / Frequency | 3-Phase, 50/60 Hz |
| Overload Relay | Thermal Overload (Typically accepts standard GE ISO heaters) |
| Coil Voltage | Dependent on prefix/suffix (Commonly 115-120V, 230-240V, or 460-480V AC) |
3. Product Advantages
- High Durability & Lifespan: Built to rigorous NEMA standards, making it much more robust against voltage spikes and harsh environmental wear than standard IEC-rated components.
- Easy Maintenance: Features toolless contact inspection and straightforward coil replacement, drastically reducing machine downtime during routine service.
- Excellent Contact Design: Weld-resistant silver-cadmium oxide contacts provide clean electrical continuity and maximize the operational life of the starter.
- Secure Overload Protection: The integrated thermal overload relay ensures precise, dependable protection against motor overheating and phase loss.
4. Key Considerations & Safety Precautions
⚠️ Important Security & Installation Notes:
- Power Disconnection: Always isolate and lock out the main power supply before installing, adjusting, or servicing this electrical equipment.
- Correct Heater Selection: The starter does not automatically protect against overloads without properly sized thermal overload heaters. Heaters must be selected separately based on the motor’s actual Full Load Amps (FLA) rating.
- Coil Voltage Matching: Ensure your control circuit voltage matches the rated voltage stamped on the starter’s encapsulated magnetic coil to avoid burnout or failure to pick up.
- Environmental Enclosure: Ensure the starter is installed within an appropriate enclosure (e.g., NEMA 1 for indoor dust-free, NEMA 4 or 12 for wet/dusty environments) to prevent environmental damage.
5. Product Applications
The GE CR306E series is widely utilized across heavy industrial automation sectors to handle demanding motor loads. Common applications include:
- Pumps and Compressors: Industrial water treatment facilities, oil/gas pipelines, and large-scale air compressor systems.
- Material Handling: High-capacity conveyor belts, sorting systems, and industrial cranes/hoists.
- HVAC Systems: Large commercial air handling units, chillers, and industrial ventilation fans.
- Manufacturing Machinery: Machine tools, mixers, grinders, and crushers where heavy-duty cycling and reliable protection are required.
