It is a 3-pole unit designed for line protection, with an adjustable thermal-magnetic trip that covers 240 A to 1 920 A, so it fits a broad range of feeder and main breaker applications in distribution panels.
Breaking capacity — what it handles at fault
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V. The drop to 4.5 kA at 690 V is expected for a 160 A frame; if your system runs 690 V, verify the available fault current stays under that ceiling.
Shunt trip and panel fit
The basic switch variant is 3VA2216-5HL32-0AA0; this -0HA0 suffix adds the shunt trip.
