What this breaker does on the line
The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and 76 kA at 440 V — numbers that tell you this breaker is built for high-fault panels where the available short-circuit current is substantial. At 500 V and 690 V it still holds 17 kA, so it covers 480 V and 600 V class systems without derating the interrupting rating below the fault level.
Thermal-magnetic curve and temperature derating
The overcurrent release is a TM220 — a fixed thermal-magnetic trip unit. At 55 °C it drops to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A.
Auxiliaries and panel fit
Dimensions are 130 mm tall, 3 in wide, 2.8 in deep. If you need those functions, you're looking at a different suffix in the 3VA family.
