The Siemens SENTRON 3VA2216-5HK32-0AA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C ambient — no derating needed across that entire span, which simplifies panel thermal budgeting when the breaker sits near other heat sources. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — the 415 V figure is the one most often checked for IEC industrial installations, and at 121 kA it handles high-fault scenarios without cascading upstream.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — the width matches the standard 3-pole MCCB footprint for Siemens SENTRON 3VA2 fixed breakers, so it drops into existing panel cutouts and busbar arrangements without re-drilling.
Insulation voltage is rated 800 V, and the operating temperature range spans -25 °C to +70 °C, with storage from -40 °C to +80 °C.
