The overload protection band runs Ir=14 A to 20 A, and the short-circuit magnetic pickup is adjustable Ii=8 to 16 times In. This variant is configured for a DC Power OEM based in China. The 4-pole form factor handles three-phase plus neutral, common in IEC panel builds for industrial or commercial sub-distribution. The nut keeper kit simplifies torque-down on the line and load terminals — a small detail that saves time during panel wiring.","metaTitle":"Siemens 3VA1120-3GF42-0AA0-ZD00 Circuit Breaker, 20A, 25kA @","metaDescription":"Siemens 3VA1120-3GF42-0AA0-ZD00 IEC frame 160 circuit breaker, 20A, Icu=25kA @ 415V, 4-pole.
