Its interrupting ratings climb to 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that tell you this breaker can clear high-fault currents on the secondary side of a distribution transformer without welding its contacts or venting arc gas into the enclosure. At 500 V the interrupting rating drops to 30 kA, and at 690 V to 4.5 kA, so it's not a candidate for 690 V high-fault panels unless the available fault current is known to be under that threshold.
Thermal derating — what 200 A means at panel ambient
At 55 °C it drops to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. Maximum power loss is 44.5 W, which matters for enclosure heat-rise calculations when the breaker is fully loaded.
Auxiliaries and releases fitted
The two auxiliary switches provide status feedback (open/closed) to a PLC or indication lamp without needing a separate contact block. If you need those, you're looking at a different suffix in the 3VA1 family.
Dimensions are 105 mm wide, 158 mm high, 70 mm deep. The 70 mm depth means it clears most shallow enclosures, but verify the door-swing clearance if the breaker is mounted near the hinge side. Rated insulation voltage is 800 V, operating temperature range -25 °C to 70 °C, storage range -40 °C to 80 °C. The storage minimum matters if this sits in an unheated warehouse over winter.
