Product Description

For the diverse requirements of our clients, we are engaged in offering an exclusive array of High Voltage Air Circuit Breakers. These are designed and developed under the guidance of technocrats utilizing supreme grade components to ensure quality. The entire range of High Voltage Air Circuit Breakers is highly demanded in the market due to optimum performance, smooth operation, compact design and longer functional life. The offered breakers are available in different specifications at competitive prices.

Specifications:

EntelliGuard SL is a new line of Air Circuit Breakers to offer a truly global product platform meeting IEC standards.
A line of three and four pole devices ranging from 200 a to 4000A om a common envelope with fault interruption ratings of 50 kA and 65 kA. A design offering a unique combination of high fault current with stand rations, short fault interruption times and selectivity.
The device includes the new state of the art EntelliGuard SL trip unit that enables the circuit breaker to provide system safety, reliability, measurement, relaying and communication using the Modbus or Profibus protocol.
EnterlliGuard SL air circuit Breakers are designed to allow multiple interruptions of fault currents. Here, the tested and certified service breaking capacity valve is in all cases equal to the stated ultimate breaking capacity.
Envelope 2 can be used in networks with voltage up to 690 V AC and can be acquired with current ratings from 2000 A to 4000 A. Envelop 2 is available in interruption ratings (ICS = ICU) of 50 kA and 65 kA.
The empty cassette is modified with minor changes accordingly in order to accommodate the new retrofit solution. The kit can be assembled at site if required can be supplied as pre - assembled also. The retrofit arrangement is ready for operation within a short span of time as the existing busbar does not require any dismantling.

Versatile IP Protection for Demanding Environments

Select from IP30, IP40, or IP54 protection levels depending on your site requirements, safeguarding sensitive components from dust and moisture. This flexibility makes these ACBs suitable for challenging industrial settings, ensuring durability and operational reliability across a wide range of environments.

Advanced Trip Unit Technology

Choose between electronic and microprocessor-based trip units to optimize protection. These feature rich devices provide precise detection and response to faults, integrated thermal protection relays, and customizable protection curves, ensuring your assets are safeguarded and downtime is minimized.

Flexible Installation and Connection Options

The design accommodates horizontal and vertical mounting, as well as rear, bottom, or top busbar connections, supporting both fixed and drawout/panel-mounted setups. This adaptability streamlines setup and maintenance, meeting the needs of fabricators, service providers, and end-users alike.

FAQs of High Voltage Air Circuit Breakers:

Q: What applications are High Voltage Air Circuit Breakers suitable for?

A: These ACBs are ideal for industrial switchgear, distribution systems, generator protection, and busbar setups in power plants, manufacturing facilities, and large commercial installations. Their robust design ensures dependable circuit isolation and protection in demanding environments.

Q: How do I select the appropriate IP protection class for my installation?

A: The choice between IP30, IP40, or IP54 depends on your sites exposure to dust and moisture. IP30 is suitable for standard indoor areas, IP40 adds protection against solid objects, and IP54 is best for locations with higher dust or moisture levels, such as industrial plants.

Q: What are the benefits of electronic or microprocessor-based trip units in these breakers?

A: Electronic and microprocessor-based trip units deliver enhanced fault detection and precise tripping, alongside customizable protection curves and integrated thermal protection. This ensures rapid response to electrical faults, reducing equipment damage and promoting system reliability.

Q: When is rear, bottom, or top busbar connection recommended?

A: The optimal busbar connection type depends on your panel layout and available space. Rear connections can streamline wiring in large switchboards, while bottom or top connections might suit compact enclosures or unique installation requirements, providing easier access and integration.

Q: What is the process for mounting these ACBs in various configurations?

A: These ACBs support fixed, drawout, and panel-mounted installation. After selecting the configuration and mounting orientation (horizontal or vertical), follow manufacturer guidelines for secure mechanical and electrical connections, ensuring proper alignment for reliable operation.

Q: Where can I source these Air Circuit Breakers in India?

A: You can purchase these breakers through certified dealers, fabricators, manufacturers, service providers, suppliers, traders, or wholesalers specializing in industrial electrical equipment across India. Many suppliers also offer after-sales support and customization services.

Q: What advantages do the expandable auxiliary contacts provide?

A: Standard auxiliary contacts (4NO+4NC) can be expanded to suit complex control requirements. This feature enhances monitoring and control flexibility, allowing integration into advanced automation systems and improving the overall functionality of your switchgear setup.
