The Siemens SENTRON 3VA2116-6HL32-0BL0 is a 3-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting ratings are what set this frame apart: 242 kA at 240 V, 187 kA at 415 V and at 440 V, 121 kA at 500 V, and 3.7 kA at 690 V.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for a 160 A frame. The 160 A rating holds flat across the operating band — no derating curve to calculate for typical industrial ambient conditions.
