It carries a continuous current rating of 63 A across the full ambient range from 40 °C to 70 °C, meaning no derating needed when the panel runs hot — that's the same 63 A at 70 °C as it is at 40 °C. The adjustable thermal-magnetic trip unit covers a range from 95 A minimum to 756 A maximum, so you set the instantaneous pickup to match the inrush of your motor or transformer load without swapping the breaker body.
This MCCB interrupts 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. At 690 V the capacity drops to 3.7 kA, so verify your available fault current if you're using this on a 690 V system.
At 105 mm wide, 181 mm tall, and 86 mm deep, this 3-pole MCCB fits standard panel cutouts for SENTRON 3VA2 frames. The depth of 86 mm (3.39 in) matters when you're laying out bus bars or rear-access wiring — make sure your enclosure depth clears it with room for cable bending radius.
Auxiliary and communication options
The base switch variant is 3VA21635JP320AA0. Communication function is built in, which on the 3VA2 platform typically means PROFIBUS or PROFINET capability for integration into a higher-level control system.
