The Siemens SENTRON 3VA2163-5JP32-0AB0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C. Its interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — so it handles high-fault industrial feeds without cascading upstream, especially on 240 V or 415 V distribution.
Dimensions: 105 mm wide, 181 mm high, 86 mm deep (4.13 × 7.13 × 3.39 in). Designed for line protection (feeder duty). Rated insulation voltage 800 V. Communication function built in — supports integration with higher-level control systems. No undervoltage release, no ground-fault monitoring, no trip indicator on this variant.
Operating temperature range -25 °C to 70 °C; storage from -40 °C to 80 °C. Maximum power loss 4 W. The 63 A rating holds steady from 40 °C through 70 °C — no derating needed in warm enclosures.
