The Siemens SENTRON 3VA2463-5HN32-0AA0 is a 3-pole molded case circuit breaker rated for 630 A continuous current at 40 °C, with an ETU350 electronic trip unit designed for line protection. The 630 A figure is the base rating at 40 °C; above that ambient the breaker derates in steps — 612 A at 45 °C, 593 A at 50 °C, down to 520 A at 70 °C — so the real-world continuous current depends on your enclosure temperature, not just the nameplate number. Breaking capacity is the other headline: 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. At 690 V the 9 kA figure is lower, which is typical for this frame size; if your system runs 690 V with high fault potential, verify coordination with the upstream device. The ETU350 release is an electronic trip unit — adjustable, more precise than thermal-magnetic for coordinating with downstream breakers in a selective scheme. Maximum power loss is 162 W, which matters for heat buildup in a sealed enclosure; factor that into your thermal calculation.

Frequently asked questions
What is the breaking capacity of 3VA2463-5HN32-0AA0 at 415 V?
121 kA at 415 V AC. At 240 V it is 187 kA, at 500 V it is 75.6 kA, and at 690 V it is 9 kA.
What does the ETU350 trip unit mean for selectivity?
The ETU350 is an electronic overcurrent release that allows adjustable long-time, short-time, and instantaneous pickup settings. This makes coordination with downstream breakers more precise than a fixed thermal-magnetic release, especially in selective schemes where you need to keep the upstream breaker closed during a downstream fault.
