FAQ's of LT (D SINE - WHITE MODEL) 400A 4P MCCB:

Q: How does the LT (D SINE - WHITE MODEL) 400A 4P MCCB protect electrical systems?

A: This MCCB uses a fixed thermal and magnetic trip unit that automatically disconnects the circuit when it detects overloads or short circuits. Its 36 kA breaking capacity ensures that even severe faults are safely interrupted to safeguard your equipment and minimize downtime.

Q: What installation orientations are supported for this MCCB?

A: The unit permits both vertical and horizontal mounting, making it versatile for a range of distribution board layouts and configurations.

Q: When should I use the D SINE curve model?

A: The D SINE curve is recommended for applications with high inrush currents, like motors or transformer circuits, as it offers greater tolerance before tripping on short-duration high surges while still providing reliable short-circuit protection.

Q: Where is the LT 400A 4P MCCB typically installed?

A: It is widely installed in three-phase industrial and commercial electrical panels where consistent overload and short-circuit protection is essential, particularly within the rated voltage of 415V AC and frequency of 50/60 Hz.

Q: What is the process for resetting the MCCB after a trip?

A: The breaker features a manual reset mechanism. Once the fault is cleared and the trip cause addressed, simply switch the handle to the 'off' position and then to 'on' to restore operation.

Q: How can optional auxiliary contacts enhance usage?

A: Auxiliary contacts can be added to enable remote signaling or interlock with other systems, offering greater operational flexibility and monitoring capabilities within automated or networked environments.

Q: What benefits does the 400A 4P MCCB offer in demanding applications?

A: Offering solid reliability, a high breaking capacity, long mechanical life, and flexible installation options, this MCCB delivers dependable protection and ensures operational continuity even in intensive or high-load settings.
