The Siemens SENTRON 3VA2010-5HL36-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection duty, carrying a continuous current Iu of 100 A and a maximum breaking capacity of 187 kA at 240 V AC. Its interrupting rating drops to 121 kA at 415 V and 440 V, then 79 kA at 500 V, and 3.4 kA at 690 V — the steep derating above 500 V means this frame is sized for 400 V-class distribution, not 690 V main feeders.
Current derating and thermal limits
Above that, derating is linear: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C.
Footprint is 105 mm wide, 181 mm tall, 86 mm deep — standard 3-pole MCCB dimensions for a 100 A SENTRON frame. Mechanical endurance is 20,000 operations.
