Superior Electrical Protection

The NV400-SW ensures consistent circuit protection through its integrated thermal-magnetic release mechanism. This advanced trip unit detects both overloads and short circuits, providing fast and reliable response. Designed to operate in ambient temperatures ranging from -5C to +40C, it maintains stable performance across various industrial conditions.

Flexible Installation & Durable Design

With its compact panel-mounting structure and secure screw terminal connections, this MCCB is straightforward to install in control panels or distribution boards. Its rugged construction allows for a mechanical life of up to 10,000 operations, and its black and grey finish fits seamlessly with modern industrial equipment.

FAQ's of MITSUBISHI (NV400-SW) 300A 3P MCCB:

Q: How does the MITSUBISHI NV400-SW protect electrical circuits?

A: The NV400-SW employs a thermal-magnetic trip unit to identify and disconnect the supply during overloads or short circuits, thereby preventing equipment damage and minimizing potential hazards.

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

A: The MCCB is designed for panel mounting and uses screw terminal connections. Simply secure the breaker to the panel and connect the incoming and outgoing wires to the respective terminals following safety protocols.

Q: When should auxiliary contacts or alarm switches be used with this breaker?

A: Auxiliary contacts and alarm switches are optional accessories that can be added when you require remote status indication or alarm signaling for events such as tripping or fault detection.

Q: Where is the NV400-SW best utilized?

A: This MCCB is ideally suited for industrial and commercial electrical distribution panels in facilities where robust three-phase protection up to 300A is needed.

Q: What are the usage benefits of its Type C curve characteristic?

A: A Type C tripping curve enables the MCCB to tolerate moderate inrush currents (such as those from motors) without nuisance tripping, making it ideal for protecting both standard and inductive loads.

Q: How does the breaker maintain performance across different temperatures?

A: Designed to operate within a -5C to +40C ambient temperature range, the NV400-SW reliably maintains accurate trip settings and performance stability in typical industrial environments.

Q: What is the rated short-circuit breaking and making capacity of this MCCB?

A: The NV400-SW has a rated short-circuit breaking capacity of 36 kA at 415V AC and a short-circuit making current of approximately 72 kA, ensuring rapid and effective circuit disconnection under fault conditions.
