It uses a TM210 thermal-magnetic trip unit with fixed overload protection (Ir = 25 A) and fixed short-circuit protection set at 12.8 × In. The neutral conductor is unprotected, and the unit includes a nut keeper kit for DC Power OEM applications in China. The fixed Ir = 25 A and Ii = 12.8 × In (320 A short-circuit pickup) make it a dedicated line-protection device; it is not adjustable, so verify your load current matches 25 A before specifying. The unprotected neutral conductor means the neutral pole does not have overcurrent protection — typical for TN systems where the neutral is bonded to ground and not expected to carry fault current.","metaTitle":"Siemens 3VA1025-3ED42-0AA0-ZD00 Circuit Breaker, 25A, 25kA @","metaDescription":"Siemens 3VA1025-3ED42-0AA0-ZD00 IEC frame 100 circuit breaker, 25A, 25kA breaking capacity @ 415V, 4-pole, TM210.
