Integrator's terse spec recap
The Siemens 3VA2216-7MQ32-0AG0 is a SENTRON molded case circuit breaker in a 3-pole, 160 A frame, built for motor protection with an ETU860M electronic trip unit. At 240 V it interrupts 330 kA; at 415 V and 440 V it holds 242 kA, dropping to 4.5 kA at 690 V — the SCCR headroom covers most industrial service-entrance and feeder applications where high fault current is expected. Rated continuous current Iu is 160 A across the full ambient range from 40 °C to 70 °C, so no derating is needed in a warm enclosure. The ETU860M release provides adjustable time-current curves, phase failure detection, and ground fault monitoring via summation current formation on the L-conductor. Communication function is onboard, and the breaker supports integration into a higher-level automation system for remote trip indication and load management.
Panel fit and mounting
The 3VA2216-7MQ32-0AG0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint for DIN-rail or screw-mount panel integration. IP40 on the front means it is protected against tools and small wires entering the enclosure face; the panel builder should plan for a sealed gland plate if washdown is required.
