The 63 A rating holds across the full ambient range from 40 °C to 70 °C (no derating needed up to the maximum operating temperature), so it fits warm enclosures without a current penalty. It carries a built-in shunt trip (STL) release rated 12-30 V DC / 24 V AC 50/60 Hz, plus two HQ auxiliary switches (form C, CO contacts). The shunt trip allows remote or emergency trip initiation via a control signal; the auxiliary switches report the main contact position back to the PLC or status panel. No undervoltage release is fitted, and no communication module is integrated. ## DIN-rail mounting and wiring Dimensions are 70 mm deep, 101.6 mm wide, 130 mm tall. Front terminals accept busbar connection for the main circuit. Mechanical service life is 15,000 switching cycles typical.","metaTitle":"Siemens 3VA1163-1AA42-0HC0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens SENTRON 3VA1163-1AA42-0HC0 switch disconnector, 63 A rated across 40-70°C, 4-pole, shunt trip 12-30V DC, 2 HQ aux contacts.
