The Siemens SENTRON 3VA2010-5HL36-0AJ0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, with a maximum breaking capacity of 187 kA at 240 V AC.
At 240 V the breaker interrupts 187 kA; at 415 V and 440 V that drops to 121 kA, then 75.6 kA at 500 V, and 3 kA at 690 V.
The 86 mm depth fits standard MCCB mounting plates and leaves room for rear-connected busbars or cable lugs without forcing a deeper enclosure.
