The Siemens 3VA2116-6HL32-0DL0 is a SENTRON molded case circuit breaker rated for 160 A continuous current (Iu) across a 40 °C to 50 °C ambient — no derating needed in that band. At 55 °C it still holds 154 A, and at 70 °C it delivers 136 A, so it handles warm enclosures without a frame size jump. Breaking capacity hits 242 kA at 240 V and 187 kA at 415/440 V — that puts it in the high-fault tier for industrial mains, meaning it can interrupt a bolted fault at the service entrance without upstream fuses needing to clear first. It ships with an undervoltage release (UVR) fitted — the release is a 3VA9608-0BB25 — and a full auxiliary contact block: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type). That covers status feedback and shunt-trip monitoring without adding a separate accessory.
Dimensions are 181 mm high × 105 mm wide × 86 mm deep — a standard 3-pole MCCB footprint for 160 A frames.
Environmental and compliance range
Operating temperature spans -25 °C to 70 °C; storage range is -40 °C to 80 °C. The 80 °C storage max means it can sit in a hot warehouse or shipping container without degrading the trip unit.
