MCCB for high-fault line protection
The 200 A rating at 40 °C is the continuous current you size the feeder for; the breaker holds that rating up to 50 °C, then derates linearly to 176 A at 70 °C, so panel ambient temperature directly affects your available ampacity. Breaking capacity is the headline spec: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Rated insulation voltage is 800 V, and operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C. This is a straightforward, high-interrupting-capacity breaker for fixed feeder protection where selectivity and coordination are done with time-current curves at the system level.
Dimensions: 105 mm wide, 158 mm high, 70 mm deep. The 3-pole frame is the standard 105 mm width for this SENTRON frame size — verify your enclosure's mounting plate space and busbar pitch before committing the BOM. The 70 mm depth means it fits shallow backpanels, but leave clearance for the arc chute exhaust and cable bending radius below the line-side lugs. Max power loss is 42 W at rated current. The auxiliary switch configuration is 1 auxiliary switch + 1 trip alarm switch HQ, which gives you a remote status contact and a separate alarm contact on trip — useful for PLC inputs or annunciator panels.
