What this MCCB carries and where it fits
The 3VA2110-6HN32-0DA0 is a SENTRON molded case circuit breaker (MCCB) rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up near the kiln or the drive cabinet. Three-pole design, line-protection function, and an integrated undervoltage release (UVR) that trips the breaker when supply voltage drops below the dropout threshold — standard for safety circuits that need to kill power on loss of control voltage. Breaking capacity hits 242 kA at 240 V and 187 kA at 415 V, so it handles high-fault-current scenarios typical of large transformer secondaries or busway feeds without cascading upstream.
Sizing and coordination for the real panel
Rated insulation voltage is 800 V. The 100 A continuous rating is flat from 40 °C to 70 °C. Maximum power loss is 12.5 W, so ventilation requirements in the panel are modest for this frame size. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — fits standard SENTRON 3VA mounting footprints. The 86 mm depth is the same as many 3VA2 frame breakers, so a panel laid out for a 3VA1020 will accept this unit without re-drilling the mounting plate.
