Siemens 5SX23 C20 Three-Phase Circuit Breaker

Siemens 5SX23-C20 is a three-pole molded-case circuit breaker from the 5SX family, rated for 20 A and featuring a C-type trip curve, designed to provide overcurrent protection for three-phase circuits in industrial control panels and electrical distribution. The 5SX23 designation identifies a 3-pole device, while the C20 suffix confirms the 20 A nominal current rating on a C-curve protective profile. Within the 5SX23 family, current ratings span from 1 A to 32 A, and variants showcase different trip characteristics including B, C, or D; the C20 variant is specifically the 20 A C-curve option. This breaker is commonly used to safeguard three-phase loads, such as motors and other equipment in standard industrial distributions, and is intended for Siemens-compatible installations requiring a compact, modular protection device.
