- HMC399 protects 3 poles against overloads and short circuits, with a C curve and 125 A rating. This is a modular DIN-rail breaker, not a molded-case compact breaker.
System position
AC protection: conceptual single-line view.
Overload and short-circuit protection, without integrated residual-current protection. Select separate leakage protection where required.
The closed device supplies L1 / L2 / L3. Downstream branch protection remains separate. PE bypasses every switched pole.

03 · Selection points
Four practical selection points.
Choose by circuit function, conductors and documented electrical limits.
- 01
Pole arrangement
L1, L2 and L3 are switched together. Neutral is not routed through this three-pole device.
- 02
Current and protection function
Curve C: match starting currents and conductor protection to the 125 A rating. Ambient temperature affects the available continuous current; use the Hager derating table.
- 03
Voltage and fault capacity
Only the consistent 400 V capacities are published. Hager records disagree at 230 V; that value and voltage-unspecified Ics values are withheld. Icn and Icu follow different standards.
- 04
Mounting and connections
DIN-rail mounting, 4.5 modules / 80 mm wide. Follow the manufacturer's terminals and installation instructions. The nominal top/bottom terminal torque is 3.6 Nm; the generic 3.5–5 Nm field is not a universal setting.
