It provides line protection via a TM240 thermal-magnetic trip unit with adjustable overload protection (Ir = 44 A to 63 A) and short-circuit protection (Ii = 5 to 10 × In). The ATAM designation indicates it includes a neutral conductor protection module at 100% and a nut keeper kit, configured for DC Power OEM applications in China. The adjustable Ir (44–63 A) lets you match the overload pickup to the actual load current, avoiding nuisance trips while still protecting the downstream cable. The Ii range of 5–10× In (315–630 A) gives flexibility for motor-start inrush or transformer magnetizing current without sacrificing short-circuit protection. The nut keeper kit simplifies torque-controlled lug connections for DC Power OEM builds. The neutral conductor protection at 100% ensures the neutral is not overloaded in single-phase or unbalanced three-phase circuits — a common requirement in IEC distribution boards.","metaTitle":"Siemens 3VA1163-3GF42-0AA0-ZD00 Circuit Breaker, 63A, 25kA @","metaDescription":"Siemens 3VA1163-3GF42-0AA0-ZD00 IEC frame 160, 4-pole, 63A, Icu=25kA @ 415V, TM240, ATAM.
