Siemens 3VA2216-7KQ42-0AA0 SENTRON MCCB, 160 A, 4-Pole, 330

The Siemens SENTRON 3VA2216-7KQ42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated for 160 A continuous current across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to the enclosure's thermal limit. That 160 A is the full-scale value, with an adjustable thermal-magnetic trip starting at 32 A, so it covers a wide band of downstream protection without swapping the breaker body. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 4.5 kA at 690 V. At 690 V the capacity drops to 4.5 kA, so if the circuit runs at that voltage, upstream coordination must limit fault current below that threshold. Ground-fault monitoring is built in via summation current formation on the L + N conductors, so it detects leakage without a separate GFCI module — a space saver on the DIN rail. Communication function is present, meaning it can report status or trip events to a higher-level system, though the protocol is not specified in this listing.
