Specifications :

Features :

• Type: Molded Case Circuit Breaker (MCCB)

• Frame Size: K-frame (generally used for current ratings above 100 amps, designed for more demanding applications).

• Poles: 3-pole (3-phase protection).

• Rated Current: 400 Amps (the KD3400 is rated for 400A).

• Voltage Rating: Typically rated for 480V AC but can also be used in other voltage systems, depending on configuration.

• Series: Series C (Siemens Series C breakers offer a combination of thermal and magnetic protection, providing reliable and adjustable protection against overcurrent conditions).

• Interrupting Capacity: The interrupting capacity of the KD3400 is typically 65kA at 480V (this high interrupting rating is one of the reasons why K-frame breakers are suitable for heavy-duty industrial and commercial applications).

Applications:

• Industrial Facilities: Commonly used in industrial motor protection, distribution panels, and switchgear systems.

• Commercial Buildings: Provides overcurrent protection in large electrical panels and switchboards.

• Large Equipment Protection: Used to protect large machinery or distribution circuits where high current levels are involved.

• Motor Protection: Particularly useful for protecting motors, especially when combined with thermal protection settings.
