What this MCCB is and where it fits
The Siemens SENTRON 3VA2110-5KP32-0HL0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels and switchboards. It carries a breaking capacity of 187 kA at 240 V AC, tapering to 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V — figures that define its fault-interruption capability across common industrial voltages. The unit includes a shunt trip release (STL), two auxiliary switches plus a trip alarm and an electrical alarm switch (HQ), and a communication function for integration into monitored systems.
Key ratings and what they mean for your panel
The 100 A continuous rating holds flat across the entire operating temperature range from -25 °C to 70 °C — no derating needed up to 70 °C, which simplifies panel layout in warm enclosures. The 187 kA at 240 V is the highest interrupting rating on this frame; at 690 V the same breaker interrupts 3.7 kA, so verify the available fault current at your system voltage. The 10 W maximum power loss is modest for a 100 A frame, keeping heat buildup manageable in a crowded DIN-rail or panel-mount arrangement.
Dimensions and panel integration
The breaker measures 86 mm deep, 105 mm wide, and 181 mm high. The 105 mm width for a 3-pole 100 A frame is standard for SENTRON 3VA2 breakers — it fits the same mounting footprint as other 3VA2 three-pole units, so a panel laid out for a 3VA2116-5JP32-0AE0 will accept this breaker without rewiring, provided the continuous current and trip characteristics match the application.
