What it is and what it does
The Siemens SENTRON 3VA2110-5HN36-0DL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with full thermal-magnetic line protection for distribution panels and feeder circuits. Breaking capacity reaches 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — covering most low-voltage fault levels across North American and IEC installations. It ships with a built-in undervoltage release (UVR) and a full auxiliary switch complement: 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ type).
Dimensions and panel fit
At 181 mm high, 105 mm wide, and 86 mm deep, this MCCB fits standard SENTRON mounting footprints and panel cutouts — verify the 105 mm width against your DIN-rail or screw-mount spacing.
