Siemens 3VA2116-5HN32-0AH0 — 160 A MCCB, 3-Pole, 187 kA IC
The Siemens SENTRON 3VA2116-5HN32-0AH0 is a 3-pole molded case circuit breaker rated for 160 A continuous current at 40 °C through 70 °C — no derating needed across that full ambient span, which simplifies panel design in warm enclosures. Interrupting capacity reaches 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V. It's a straight thermal-magnetic or electronic-trip MCCB for feeder or main service.
Mounting & panel fit
The width of 105 mm is the 3-pole frame footprint; verify busbar or lug spacing against the panel layout. Maximum power loss is 25.5 W at rated current.
That's a fixed assembly — you're not adding a field-installable accessory block. The supplied basic switch order code is 3VA21165HN320AA0, which confirms the internal mechanism variant.
