Siemens 3VA2463-5JP32-0AF0 — 630 A SENTRON MCCB for Line Protection
This 3-pole breaker delivers a breaking capacity of 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — covering most low-voltage fault scenarios in a single frame. It carries a communication function, making it suitable for integration into monitored or automated power schemes where trip events and load data need to be reported upstream.
Derate to 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C — the full thermal curve is defined for panel design. Maximum power loss is 162 W, which matters for enclosure heat rise calculations when the breaker is loaded near its rating in a sealed cabinet.
