The Siemens SENTRON 3VA2116-5HN32-0CL0 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. Breaking capacity reaches 187 kA at 240 V AC and 121 kA at 415/440 V, dropping to 75.6 kA at 500 V and 3.7 kA at 690 V — the 690 V figure is low, so verify coordination if the fault level at that voltage exceeds it.
Integrated auxiliaries and releases
The auxiliary switch set provides status feedback for PLC or SCADA inputs. The basic switch assembly is order code 3VA21165HN320AA0, meaning the main contact and arc chamber are a replaceable subassembly if the breaker takes a fault and needs refurbishment rather than full replacement. Maximum power loss is 28 W at rated current, which matters for thermal management in a sealed enclosure.
No IP rating is listed in the spec set, so it is intended for indoor panel installation, not washdown or outdoor exposure.
