At 415/440 V the 121 kA rating still covers heavy industrial fault levels. The drop to 75.6 kA at 500 V and 3.7 kA at 690 V means this breaker is not suited for 690 V main feeders with high fault current — for that voltage class you would step up to a higher-rated frame. The 100 A continuous rating is flat across the temperature range, so no thermal derating tables are needed for panel design. ## Physical Fit and Auxiliary Configuration A communication function is built in, enabling integration with energy management or SCADA systems. Maximum power dissipation is 10 W at rated load, which is modest for a 100 A frame — panel ventilation requirements are minimal.","metaTitle":"Siemens 3VA2110-5JQ32-0KL0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5JQ32-0KL0 molded case circuit breaker, 100 A, 3-pole, 187 kA interrupting at 240 V.
