Rated current and breaking capacity
The Siemens 3VA2163-7HL32-0AA0 is a SENTRON molded case circuit breaker (MCCB) rated for a continuous current of 63 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel thermal budgeting for a cold-storage or freezer line where ambient stays well below 40 °C. Breaking capacity is voltage-dependent: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Trip unit and protection design
Insulation voltage is rated at 800 V.
