Overcurrent breaker S 301 1P B 20 A 6000 A DX3 series 407433

Protection of Installations and Equipment – Legrand DX3 Circuit Breaker

This single-pole circuit breaker from Legrand’s DX3 series provides reliable protection for your electrical installation. Designed to safeguard circuits with a rated current of 20A, it offers effective protection against overloads and short circuits. The B characteristic makes it ideal for circuits with resistive and inductive loads featuring moderate inrush currents, such as lighting and socket outlets.

This breaker stands out with its compact dimensions—just one module (18mm) wide—enabling efficient use of space in distribution boards. The flush mounting further enhances the aesthetic appearance of the installation. The rated short-circuit breaking capacity of 6kA at 230V and 10kA in accordance with IEC 60947-2 ensures safety in the event of a fault.
