160 A MCCB with full-rated thermal performance
The Siemens 3VA2116-5JQ32-0AH0 is a SENTRON 3-pole molded case circuit breaker rated at 160 A continuous current, and it holds that rating across the full ambient temperature range from 40 °C through 70 °C — no derating curve to chase for standard panel environments. Interrupting capacity reaches 187 kA at 240 V, stepping down to 121 kA at 415 V and 440 V, and 75.6 kA at 500 V; at 690 V the rating drops to 3.7 kA, which defines the upper voltage boundary for this frame.
Electrical ratings and trip characteristics
The thermal-magnetic trip unit is set at a fixed rating of 160 A full-scale, with an initial pickup value of 32 A — this is the long-time delay threshold, not the instantaneous magnetic pickup.
