Information About HKD3400
The HKD3400 is part of Eaton’s Series C lineup, utilizing a rugged K-Frame molded case design optimized for robust electrical distribution environments. It incorporates a fixed thermal-magnetic trip mechanism that ensures consistent protection performance across three-phase circuits. Supporting operation at 600 VAC and 250 VDC with 50/60 Hz compatibility, it integrates easily as a complete breaker unit with line and load terminations. With interrupting ratings up to 100 kAIC at 240 VAC and 65 kAIC at 480 VAC, the HKD3400 is engineered for installations requiring strong fault-handling capability and long-term durability.
Key Features
- 400A molded case breaker: Supports high-capacity electrical distribution.
- 3-pole K-Frame design: Suitable for three-phase power systems.
- Fixed thermal–fixed magnetic trip: Ensures stable overload and fault protection.
- Rated 600 VAC / 250 VDC: Supports a wide range of AC and DC applications.
- High interrupting capability: 100 kAIC at 240 VAC; 65 kAIC at 480 VAC.
- Durable aluminum construction: Provides strength for demanding environments.
- Series C compatibility: Designed for use in industrial and commercial installations.
- Line and load configuration: Simplifies integration into distribution equipment.
The HKD3400 delivers the reliability and precision required for high-capacity overcurrent protection in Series C K-Frame electrical systems.
