What this MCCB delivers
The Siemens SENTRON 3VA2010-5HL32-0KA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That thermal stability makes it a solid pick for warm enclosures or panels near process heat. Breaking capacity hits 187 kA at 240 V, drops to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. The adjustable trip range spans 150 A to 1 200 A, meaning the same frame can be tuned for different load sizes during commissioning — useful when panel designs evolve.
Maximum power loss is 13.5 W — negligible for panel thermal budgeting, but worth noting if the breaker is in a sealed, uncooled cabinet with other high-current devices.
