The Siemens SENTRON 3VA2163-5HL36-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current at up to 70 °C ambient — no derating needed across that range, which simplifies panel layout when the breaker sits near warm drives or transformers. Its interrupting capacity hits 121 kA at 415 V, meaning it can safely clear a fault well into the high-fault-current range typical of industrial distribution downstream of a large transformer.
Breaking capacity profile
The 3VA2163-5HL36-0AF0 delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the steep drop at 690 V tells you this breaker is optimized for 400–480 V class systems, not 690 V industrial grids. Rated insulation voltage is 800 V.
Dimensions and panel fit
The breaker ships with one auxiliary switch and one trip alarm switch (HQ type) integrated, so you get status feedback without adding external contact blocks.
Environmental and compliance
Operating temperature range spans -25 °C to 70 °C; storage range is -40 °C to 80 °C — the storage low end covers cold warehouse conditions without special handling. Maximum power loss is 4 W, so heat dissipation inside the enclosure is minimal — no forced cooling required for the breaker itself.
