About ABB SACE TMAX 320 AMP MCCB

MCCB stands forMolded Case Circuit Breaker. It is another type of electrical protection device which is used when load current exceeds the limit of a miniature circuit breaker. The MCCB provides protection against overload, short circuit faults and is also used for switching the circuits.

Flexible and Secure Protection

The ABB SACE TMAX 320 AMP MCCB ensures secure and adaptable circuit protection. With adjustable B, C, and D curve settings and robust thermal-magnetic trip elements, it tackles different fault scenarios reliably. Its front IP20 degree of protection enhances operator safety while maintaining performance across temperatures from -25C to +70C.

Versatile Installation Options

This MCCB is engineered for compatibility with varied installation requirements. Whether as a fixed, plug-in, or withdrawable device, and for both vertical and horizontal placements, it fits seamlessly into new projects or upgrades. Box/lug terminals and optional auxiliary contacts further expand its application versatility.

FAQ's of ABB SACE TMAX 320 AMP MCCB:

Q: How is the ABB SACE TMAX 320 AMP MCCB installed in electrical panels?

A: The ABB SACE TMAX 320 AMP MCCB supports fixed, plug-in, and withdrawable installations. With vertical or horizontal mounting options and box/lug terminal types, it integrates easily into a wide range of panel configurations for three-phase systems.

Q: What standards and certifications does this MCCB comply with?

A: This molded case circuit breaker complies with IEC 60947-2, which sets global requirements for power switching protection, ensuring optimal safety and quality for industrial and commercial applications.

Q: When should I use the adjustable trip ranges of this MCCB?

A: Adjustable thermal (0.7-1 x In) and magnetic (5-10 x In) trip settings should be configured during installation or commissioning based on system load and protection requirements. Proper adjustment enhances protection against overload and short-circuit events.

Q: Where can the ABB SACE TMAX 320 AMP MCCB be utilized?

A: This MCCB is suitable for use in industrial, commercial, or utility power distribution systems within the rated voltage (690 V AC) and frequency (50/60 Hz) specifications, ideal for distributors, suppliers, and exporters across India.

Q: What process does the MCCB use for overcurrent and short-circuit protection?

A: The device employs both fixed and microprocessor-based trip units containing thermal and magnetic trip elements. Thermal trips respond to prolonged overload, whereas magnetic trips react instantly to high short-circuit currents.

Q: How does the MCCB benefit electrical installations?

A: Its precise adjustment, reliable protection, and high breaking capacity (36 kA at 415 V AC) result in minimized downtime, increased operator safety, and longer equipment life. Optional features, such as auxiliary and neutral protection, provide tailored functionality.
