CONTROL CONCEPTS 330-T25 Power regulator

Description

CONTROL CONCEPTS 330-T25 Power regulator

Product Dimensions：

The c3controls Series 330 Motor Protection Circuit Breaker (MPCB) is a multi-function device designed to provide reliable protection and control for electric motors. The 330-T25 is the base product number for a range of devices within this series that have a maximum current rating of up to 25 Amps, typically featuring a rotary actuator.

• Core Function: It combines the functions of an overload relay, a short-circuit protective device (circuit breaker), a manual motor starter, and a disconnect switch into a single, compact unit.

• Trip Elements: Features Thermal-Magnetic trip elements, offering protection against both:

  • Thermal Overload: Protection against sustained overcurrents (like a motor drawing too much current due to a mechanical jam).

  • Magnetic Short Circuit: Protection against sudden, high currents resulting from a short circuit or ground fault.

• Design: Designed for mounting on a standard 35mm DIN rail.

⚙️ Product Parameters (Specifications)

The exact specifications depend on the full model number (e.g., 330-T25S2U25, 330-T25S2D20, etc.), but here are the typical general and base ratings for the 330-T25 series:

✅ Product Advantages

The Series 330 MPCB offers several key benefits for industrial motor control applications:

• Space Savings: By consolidating four functions (overload relay, short-circuit breaker, motor starter, and disconnect) into one compact device, it significantly reduces the required panel space and enclosure size.

• Simplified Installation and Wiring: It mounts quickly onto a DIN rail, and the modular design allows for easy snap-on installation of accessories (like auxiliary contacts, shunt trips) without tools, lowering labor costs.

• High Safety and Reliability:

  • Self-Protected Type E: The Type E rating means the device is self-protected and does not necessarily require an additional upstream fuse or circuit breaker for short-circuit protection, simplifying system design.

  • High Fault SCCR: The high Short Circuit Current Rating (e.g., 50kA) ensures safety and reliable protection in high-fault current environments.

  • Circuit Isolation/Lockout: Provides a lockable disconnecting means, ensuring safety for maintenance and repair personnel.

• Adjustable Current Setting: The full load current (FLA) is adjustable, allowing the overload protection to be precisely set to the exact rating of the motor being protected, ensuring optimal performance.

• Trip Indication: Optional accessories can provide trip indication (overload or short circuit), simplifying troubleshooting and minimizing downtime.

⚠️ Important Considerations (Notes)

• Full Part Number: Always refer to the complete part number (e.g., 330-T25S2U20) and the official datasheet to confirm the exact current adjustment range (e.g., 16 to 20 Amps) and voltage rating.

• Motor FLA: The MPCB’s current setting must be precisely matched to the motor’s Full Load Amperage (FLA) for proper overload protection. Incorrect settings can lead to motor damage or nuisance tripping.

• Accessories: For full functionality (e.g., remote tripping, control panel indication), you may need to purchase snap-on accessories like auxiliary contacts or shunt releases separately.

• Application Standards: Ensure the product’s ratings (especially SCCR) meet the requirements of your specific installation and local electrical codes (e.g., UL, IEC, NEMA standards).

🛠️ Product Applications

The c3controls Series 330 MPCB is used across a broad range of industrial and commercial applications for motor control and protection:

• Motor Control Panels: Used in control cabinets and panels for manual starting, stopping, and protection of individual 3-phase motors.

• Group Motor Installations: Ideal for applications where multiple motors are housed in one enclosure, providing space, labor, and cost savings.

• Machinery and Equipment: Commonly found protecting motors in:

  • Pumps and Compressors

  • Conveyors and Material Handling Systems

  • HVAC systems (Fans, Blowers)

  • Machine Tools and Process Equipment

• Motor Disconnect: Certified as a Manual Motor Controller Suitable as a Motor Disconnect, providing the necessary isolation for maintenance.
