HLC3400 | Circuit Breaker | 400A | 3-Pole | 600V

Introducing HLC3400 — an industrial circuit breaker engineered for reliability in demanding electrical environments. With a robust 400A rating across a 3-pole configuration and a 600V operating range, this unit is designed for maintenance, retrofit, and replacement tasks where exact specifications matter most.

Designed for 3-phase systems, the HLC3400 provides dependable overcurrent protection for panels and distribution boards that require precise current handling and voltage rating. The 400A rating ensures you can protect feeder circuits and main distribution paths without oversizing components, helping keep equipment safe and downtime minimal.

• Amperage: 400A
• Pole configuration: 3-Pole
