Its breaking capacity hits 242 kA at 240 V AC, dropping to 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V — that 242 kA figure at 240 V tells you this is built for high-fault utility entrance or sub-distribution panels where available short-circuit current is extreme.
Line protection design with auxiliary switch provision
This MCCB is designed for line protection (cable/feeder protection), not motor protection — no adjustable thermal or magnetic trip settings are listed for motor starting duty. It ships with two HQ auxiliary switches built in, giving you status feedback for PLC or SCADA monitoring without an add-on module. Power loss is 4 W maximum at rated load.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard SENTRON 3VA2 frame size that fits existing 3VA panel cutouts and busbar arrangements.
