What the ratings mean for fit
The Siemens SENTRON 3VA2116-5HL36-0DL0 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. That flat thermal curve simplifies panel design: you size the bus and enclosure for 160 A and don't recalculate for elevated cabinet temperatures. The breaking capacity is 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 187 kA at 240 V is the headline number, but the 121 kA at 415 V is what governs most industrial distribution panels in North American 480Y/277 V or European 400 V systems — it safely interrupts a fault up to that level without cascading upstream, which is the SCCR the panel label needs. The 3.7 kA at 690 V is a residual capability for high-voltage low-fault-current applications; don't rely on it for a 690 V main. The breaker includes an undervoltage release (UVR) and a trip indicator, plus a complement of 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch — enough for remote status monitoring without an add-on module.
Panel integration and mounting
The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures designed for SENTRON 3VA frames. The 86 mm depth is the dimension to check against the enclosure door clearance and the bus-bar standoff. The 28 W maximum power loss at rated current is the heat the enclosure must dissipate; for a 160 A breaker in a sealed cabinet, that usually means either a larger enclosure or forced ventilation above 40 °C ambient.
