What this MCCB delivers
The Siemens SENTRON 3VA2163-7JP36-0AA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C through 70 °C — no derating needed across that entire ambient span, which simplifies panel layout in warm enclosures (–,). Its ETU550 electronic trip unit supports adjustable overload and short-circuit protection curves, and the breaker carries a communication function for integration into higher-level monitoring systems. The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V (–), giving it strong fault-clearing capability across common low-voltage distribution voltages.
Panel fit and mounting
The 3VA2163-7JP36-0AA0 measures 105 mm wide, 181 mm high, and 86 mm deep (–). It mounts on a DIN rail or can be screw-fixed in a panel. The front face carries IP40 protection, meaning it is protected against tools and small solid objects — standard for enclosed distribution boards. No undervoltage release is fitted, and there is no ground-fault monitoring version; those functions would need an external module or a different variant.
