FAQs of L&T 2000A AIR CIRCUIT BREAKER:

Q: How does the microprocessor/electronic trip unit improve the performance of the L&T 2000A Air Circuit Breaker?

A: The microprocessor/electronic trip unit enhances the accuracy and responsiveness of the breaker by providing precise detection and control of overloads, short-circuit, and ground faults. Its programmable settings allow for tailored protection, ensuring the reliability and safety of connected electrical equipment.

Q: What are the available installation options for this circuit breaker?

A: The L&T 2000A Air Circuit Breaker can be installed in both fixed and drawout configurations. Additionally, it supports either vertical or horizontal mounting positions to suit a variety of panel designs and installation requirements.

Q: When should auxiliary and alarm contacts be used in power systems?

A: Auxiliary (NO/NC) and alarm contacts are essential when remote signaling or status feedback is required. They help monitor breaker conditions, trigger alarms, and integrate the circuit breaker into building management or control systems for enhanced safety and automation.

Q: Where is this breaker typically implemented in electrical installations?

A: This breaker is ideal for main incomer duties, HVAC systems, and power distribution panels in commercial, industrial, or critical infrastructure setups where reliable circuit isolation and protection are paramount.

Q: What process should be followed to select the appropriate degree of protection (IP rating)?

A: The standard IP30 degree is suitable for general indoor use. However, if the breaker is to be installed in environments exposed to dust or moisture, selecting an enclosure offering up to IP54 protection is recommended to safeguard against ingress and ensure long-term reliability.

Q: How does the breakers temperature protection feature benefit an installation?

A: Integrated temperature protection helps prevent overheating by continuously monitoring the internal temperature and activating protective measures as needed, thereby reducing the risk of damage to connected equipment and increasing operational safety.

Q: What are the connection options provided for this air circuit breaker?

A: The L&T 2000A Air Circuit Breaker supports both front and rear electrical connections, offering flexibility to accommodate diverse panel layouts and cable management preferences.
