160 A MCCB with flat thermal response to 70 °C
The Siemens SENTRON 3VA2116-5HN36-0AG0 is a 3-pole molded case circuit breaker rated 160 A continuous current, with a rated insulation voltage of 800 V. It holds its full 160 A rating across the entire ambient range from 40 °C to 70 °C — no derating curve to chase when the panel runs hot. Interrupting capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V, so it handles high-fault service entrance or distribution positions where the available fault current is substantial.
Panel fit and integration
Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard MCCB footprint for a 160 A frame. The supplied basic switch is 3VA21165HN360AA0, and the auxiliary switch configuration is one auxiliary switch plus one trip alarm switch (HP type). No undervoltage release, no ground-fault monitoring, no communication function on this variant — it's a straight line-protection breaker. Maximum power loss is 25.5 W, so account for that in enclosed panel thermal calculations.
