Versatile and Durable Design

Equipped with panel mounting options and fixed terminals, this MCCBs compact form (161 x 105 x 83 mm) fits seamlessly into most electrical panels. Its impressive mechanical life of 20,000 operations and wide ambient temperature (-25C to +70C) support enduring performance.

FAQs of MERLIN GERIN (NS 100H) 50 AMP MCCB:

Q: How do I install the MERLIN GERIN NS 100H 50 AMP MCCB?

A: The NS 100H MCCB supports fixed or panel mounting, making it compatible with most standard electrical panels. Ensure the correct wiring is adhered to, fitting the three poles according to your phase requirements, and always follow manufacturer and local electrical safety standards.

Q: What environments are suitable for using this MCCB?

A: This MCCB is specifically designed for industrial and commercial installations, capable of operating reliably in environments ranging from -25C to +70C, thanks to its flame retardant plastic enclosure and IP20 protection level.

Q: When should I use the adjustable overload and short circuit settings?

A: Utilize the adjustable settings for overload and short circuit protection when circuit requirements or connected loads vary. Adjustments help fine-tune the MCCB to provide optimal protection for sensitive or high-value equipment.

Q: Where should this MCCB be installed for optimal performance?

A: Install the NS 100H MCCB inside switchboards or main distribution panels located in clean, dry, and ventilated environments to maximize safety and device lifespan.

Q: What is the benefit of the thermal-magnetic trip unit in this MCCB?

A: The integrated thermal-magnetic trip unit offers rapid response to overcurrent and short-circuit faults. This dual protection mechanism ensures reliable and quick disconnection, minimizing equipment damage and enhancing safety.

Q: How does the MCCB ensure enhanced safety in electrical systems?

A: It provides robust circuit protection with a 36 kA breaking capacity at 415V AC and handles up to 75 kA peak short circuit making current. These features, along with a flame retardant enclosure and H-curve response, reduce the risk of electrical faults and fire hazards.
