HMDL3400 - 400Amp Circuit Breaker Description
HMDL3400 - 400Amp Circuit Breaker
When an existing electrical system calls for an Eaton HMDL3400, getting the specifications right matters. This 400A, three-pole molded-case circuit breaker is part of Eaton's Series C line and uses the MDL frame, an HMDL breaker configuration, and a T186 trip type. It operates at 50–60 Hz and carries interrupting ratings of 100 kAIC at 240 VAC and 65 kAIC at 480 VAC. Those details are especially important when you're replacing a breaker in existing or legacy equipment, where the correct form, fit, and electrical ratings must match the application.

Where It Works Best
The Eaton HMDL3400 makes the most sense for existing electrical distribution equipment designed for a 400A, three-pole HMDL Series C molded-case circuit breaker with an MDL frame. That makes it particularly relevant for maintenance and replacement work where keeping the original breaker configuration is important.
