Why this 3-Pole 400A breaker fits your power system

In three-phase electrical networks, a 3-pole circuit breaker disconnects all live conductors simultaneously when an overcurrent or fault occurs. This cohesive disconnection prevents partial tripping and helps protect motors, drives, and associated control gear from damage. The 400A rating makes it suitable for high-capacity feeders and large equipment loads commonly found in industrial facilities and commercial operations.

Ideal use cases

• Main feeder protection in distribution panels and switchboards
• Protection for motors and motor control centers in industrial environments
• OEM applications requiring robust 3-phase overcurrent protection in custom panel builds
• Panelboard and control panel upgrades where reliable trip performance matters
