About L&T 800A AIR CIRCUIT BREAKER

Air circuit breaker is a circuit breaker for the purpose of protecting low voltage circuit, mainly for energizing and cutting off high current. It is used as the master of a factory and building, and as a main circuit breaker of a ship, and it is possible to attach various accessories according to the purpose.

Advanced Protection and Monitoring

Equipped with a sophisticated microprocessor trip unit, the L&T 800A Air Circuit Breaker provides accurate detection and response to electrical faults. Its digital display and LED indicators for trip, ON, and OFF status simplify operation and status checks, enhancing safety and troubleshooting efficiency in complex installations.

Flexible Installation and Configuration

This breaker is adaptable for both fixed and draw-out installations, and can be panel mounted. Users can choose from front or rear connections and benefit from a wide control voltage range of 110-220V AC/DC. Its service life of up to 15 years and mechanical endurance up to 10,000 operations make it ideal for demanding, long-term applications.

FAQ's of L&T 800A AIR CIRCUIT BREAKER:

Q: How does the microprocessor-based trip unit enhance the performance of the L&T 800A Air Circuit Breaker?

A: The microprocessor trip unit provides precise and programmable protection functions, including overload, short circuit, and earth fault detection. This improves response times and allows for customization to specific application needs, resulting in enhanced safety and efficiency.

Q: What operational environments and installation options are supported by this circuit breaker?

A: The L&T 800A Air Circuit Breaker can operate reliably within a temperature range of -5C to +55C. It supports both fixed and draw-out installation types and is suitable for panel mounting, allowing flexibility in various industrial and commercial settings.

Q: When should the breaker's service life or mechanical life be considered for replacement?

A: It is recommended to consider replacement after approximately 15 years of service or following 10,000 mechanical operations, whichever occurs first. Actual replacement timing may depend on usage conditions and regular maintenance checks.

Q: Where can the L&T 800A Air Circuit Breaker be used effectively?

A: This circuit breaker is ideal for use in industrial facilities, commercial buildings, and critical electrical distribution panels requiring robust three-phase protection and high breaking capacity (50 kA at 415V AC).

Q: What process is involved in setting protection curves for different applications?

A: Protection curves-Long (L), Short (S), and Instantaneous (I)-are programmable via the digital interface. This allows users to tailor the breaker's response to specific load and fault conditions, optimizing protection based on system requirements.

Q: How do the display and LED indicators assist in usage and maintenance?

A: The digital status display provides real-time information on the breaker's settings and operating status. LED indicators show trip and ON/OFF states, facilitating quick status checks and aiding in efficient maintenance and troubleshooting.

Q: What are the benefits of the additional accessories such as the motor operator, shunt/under-voltage trip, and alarm contacts?

A: These accessories add remote operation, advanced fault signaling, and improved system interlocking-enhancing automation, system integration, and operational safety.
