The Siemens SENTRON 3VA2116-5HL46-0AA0 is a 4-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. It carries an ETU320 electronic trip unit, which means the protection curve is adjustable for selective coordination downstream.
The interrupting ratings climb to 187 kA at 240 V AC, drop to 121 kA at 415 V and 440 V, then to 75.6 kA at 500 V, and settle at 3.7 kA at 690 V.
No undervoltage release or shunt trip is built in.
