The Siemens SENTRON 3VA2116-5HL36-0DA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current (no derating needed across the full 40–70 °C operating range — it holds 160 A flat from 40 °C up to 70 °C). That thermal stability matters when you're packing breakers into a warm enclosure: you don't lose ampacity as the cabinet heats up. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For a 160 A frame, that's high-end interrupting capability, likely driven by the SENTRON 3VA platform's arc-quenching chamber design.
Line protection with undervoltage release — what it does and where it fits
No ground-fault monitoring, no communication function, no voltage trigger, and no trip indicator on this SKU. It's a straightforward thermal-magnetic or electronic-trip line protection breaker with UVR — no frills, no extra failure points. The basic switch assembly is order code 3VA21165HL360AA0.
The 105 mm width is a 3-pole frame.
