The Siemens 3VA2116-5JP36-0AF0 is a SENTRON molded case circuit breaker (MCCB) in the 3VA2 series, configured as a 3-pole line protection device with an ETU550 electronic trip unit. It carries a rated continuous current (Iu) of 160 A across the full ambient temperature range from 40 °C through 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting. The breaking capacity figures tell you where it can sit in a fault-current study: 187 kA at 240 V, 121 kA at 415 V and 440 V, 76 kA at 500 V, and 3.8 kA at 690 V.
Footprint is 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB form factor for DIN-rail or direct-panel mounting.
Environmental and endurance specs
