What this MCCB delivers for the panel
The Siemens SENTRON 3VA2110-6HN36-0CA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current across the full operating temperature range from 40 °C to 70 °C — no derating needed up to that ceiling. Its interrupting capacity hits 242 kA at 240 V and still holds 187 kA at 415 V, which gives you serious fault-clearing headroom on a 480 V or 400 V distribution panel without cascading upstream breakers. The 86 mm depth and 105 mm width keep it within a standard MCCB footprint for retrofit into existing SENTRON or legacy Siemens panels.
Line protection with undervoltage release
This breaker is built for line protection — feeder or main distribution duty — not motor branch-circuit protection. It ships with an integrated undervoltage release (UVR) that trips the breaker when supply voltage drops below a set threshold, which is a common requirement for safety disconnects on conveyor lines or process skids where a brownout must drop the load. The UVR is factory-fitted, so you avoid the separate aux module and wiring step.
