It carries fixed thermal-magnetic line protection (TM210) with Ir set at 25 A and short-circuit pickup Ii at 12.8 × In. The N conductor is protected at 100%. The fixed Ir at 25 A and Ii at 12.8 × In (320 A) means this unit is pre-configured for a specific load; no thermal dial adjustment is possible. The 100% N protection suits 4-wire systems where neutral current can approach phase current, common in harmonic-rich loads like VFD-fed lines.","metaTitle":"Siemens 3VA1125-4GD42-0AA0-ZD00 Circuit Breaker, 25A, 36kA @","metaDescription":"Siemens 3VA1125-4GD42-0AA0-ZD00 IEC frame 160 circuit breaker, 25A, 36kA breaking capacity @ 415V.
