Frequently bought together

The 4-pole D-curve circuit breaker is designed to protect circuits with strongly inductive loads or high capacitances, such as industrial motors and transformers. Due to its ability to trip when the current exceeds 10 to 20 times the rated current, it prevents unwanted trips during current peaks. It has a short-circuit rating of 10 kA, ensuring safety even during electrical faults.

 

The trip curve D of circuit breakers is designed to protect circuits with strongly inductive loads or high capacitances, such as transformers or heavy industrial machinery.

 

This curve trips when the current exceeds 10 to 20 times the rated current, making it suitable for handling extremely high inrush currents, typical in industrial devices that require large amounts of power at startup.

 

D-curve circuit breakers prevent unwanted tripping caused by current spikes during operation of such equipment.

 

Features:

  • Number of poles: 4
  • Class of trip characteristic D

  • Insulation voltage at maximum DC rating: 440V
  • Protection class: IP20, with conductors connected
  • Height: 90mm
  • Width: 72 mm
  • Depth 76 mm
  • Number of width modular units 4
  • Ambient temperature during operation: -25/+55 degrees
  • Ambient temperature during storage: -40/+75 degrees
