The Siemens SENTRON 3VA2225-6HN32-0AC0 is a 3-pole molded case circuit breaker rated for 250 A continuous current at 40 °C through 50 °C — meaning it holds full current without derating across the typical panel ambient range. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V, 121 kA at 500 V, and 6 kA at 690 V. At 690 V the 6 kA figure is modest; this breaker is not intended for 690 V high-fault applications. Dimensions are 181 mm height, 105 mm width, 86 mm depth — it fits standard SENTRON 3VA panel cutouts.
Integration and auxiliary options
The breaker ships with 2 auxiliary switches (HQ type) pre-installed — no separate auxiliary release or undervoltage release is fitted. The basic switch variant is 3VA2225-6HN32-0AA0. Maximum power loss is 48 W, so factor that into panel thermal calculations.
