The interrupting capacity hits 187 kA at 240 V and still holds 121 kA at 415 V; at 690 V it drops to 4.5 kA, so watch the voltage on high-impedance fault paths. The 3VA2216-5JP32-0AA0 includes a communication function, meaning it can talk to your control system for metering and status — useful for condition monitoring without adding a separate power meter.
The 3VA2216-5JP32-0AA0 measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard 3-pole MCCB footprint that drops into most SENTRON panelboards and distribution blocks.
Trip unit and protection range
The ETU550 is an electronic trip unit with a 240 A minimum to 1 920 A maximum continuous current adjustment band — that is a 8:1 range, giving you flexibility to re-rate the breaker for different loads without swapping hardware. The line protection design (no ground-fault monitoring version) means it is intended for feeder and main breaker duty, not equipment ground-fault protection.
