What this MCCB delivers — and what it doesn't
The Siemens 3VA2116-5HN36-0JL0 is a SENTRON 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, which simplifies panel thermal budgeting. Interrupting capacity is 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is low, so confirm fault current at that voltage before specifying. This is a line-protection design (not motor-protection) with no undervoltage release, no ground-fault monitoring, and no communication function — it is a straightforward thermal-magnetic MCCB with a shunt trip (STL) and a complement of auxiliary switches: 2 auxiliary + 1 trip alarm + 1 electrical alarm switch HQ.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a 3-pole frame that occupies standard MCCB panel space; verify the mounting footprint against your existing backplate or DIN-rail adapter. Maximum power loss is 25.5 W — factor this into enclosure ventilation calculations, especially in sealed cabinets.
