What this 100 A MCCB carries — and where it fits
The Siemens SENTRON 3VA2010-6JP46-0CA0 is a 4-pole molded case circuit breaker rated 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity reaches 242 kA at 240 V AC and holds 187 kA at 415 V and 440 V, then drops to 121 kA at 500 V and 3 kA at 690 V — so the voltage class of your system determines the fault-clearing headroom. The breaker carries its full 100 A without derating across the ambient range from 40 °C to 70 °C, which simplifies panel layout when the breaker sits near other heat sources.
Integrated undervoltage release and communication
This variant ships with an undervoltage release (UVR) fitted — the auxiliary release design is listed as undervoltage release (UVR), so it drops the breaker when control voltage falls below the dropout threshold. It also carries a communication function onboard, which means it can report status or accept remote trip commands over the SENTRON communication bus without an add-on module. The power loss at full load is 16 W maximum, a figure to include in your enclosure thermal budget.
Panel fit — dimensions and mounting
The breaker measures 86 mm deep, 140 mm wide, and 181 mm high. It mounts on a DIN rail or can be screw-fixed to a backplate. The 4-pole format means it occupies four module widths in a standard distribution board. Rated insulation voltage is 800 V, so it suits 400 V and 480 V systems with margin to spare.
