FAQ's of 200A 3P MERLIN GERIN MCCB:

Q: How do I adjust the magnetic trip setting on the NS200N MCCB?

A: The NS200N MCCB allows adjustment of the magnetic trip between 8-10 times the nominal current (In) using the dedicated adjustment dial on the trip unit. This enables precise short-circuit protection based on application requirements.

Q: What benefits does the thermal magnetic trip unit offer in this MCCB?

A: The thermal magnetic trip unit provides dual-mode protection: the thermal element guards against prolonged overloads, while the magnetic release swiftly interrupts large short circuit currents, ensuring operational safety and equipment longevity.

Q: Where can the NS200N MCCB be installed effectively?

A: Owing to its panel mounting and front terminal connection options, the NS200N MCCB is ideally suited for commercial and industrial electrical panels. Its enclosure protection and operating temperature range make it suitable for installations in varied environments within India.

Q: When is it recommended to use auxiliary contacts or shunt trip modules with this MCCB?

A: Auxiliary contacts and shunt trip modules are recommended whenever remote signaling, monitoring, or emergency tripping-such as integration into building management systems-is required. These accessories can be added during initial installation or as upgrades.

Q: What is the process for installing the NS200N MCCB in a panel?

A: Installation involves mounting the MCCB securely in the panel, connecting the three-phase wiring to the front terminals, and ensuring that the device rating matches the application. Accessories like auxiliary contacts or shunt trips can be fitted if required.

Q: How does the NS200N MCCB maintain safety in extreme temperature conditions?

A: Designed to operate reliably from -20C to +70C, the NS200N MCCB uses durable materials and effective trip mechanisms, supported by its IP20 terminal protection and IP40 enclosure rating to safeguard both users and electrical systems.

Q: What advantages does the 36 kA breaking capacity provide to users?

A: A breaking capacity of 36 kA at 415V AC ensures the NS200N MCCB can safely interrupt severe fault currents, reducing risk of damage to downstream equipment and improving operational continuity in critical electrical installations.
