This Siemens 3VA5 series molded-case circuit breaker, part number 3VA5110-5EC32-0AA0, is engineered for robust system protection. It features a 3-pole configuration with a rated operational current of 100A at 40°C, derating to 87A at 70°C. The breaker is designed for a maximum operating voltage of 690V AC and offers significant breaking capacities, including 35kA at 480V according to UL standards and 55kA at 415V according to IEC standards.
With a mechanical service life of 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles at 380/415V AC-1, this circuit breaker is built for durability. It includes overload protection (Ir=100A) and fixed short-circuit protection (Ii=5...10 x In) with the TM230 overcurrent release. The unit is HACR Type compliant.
Mechanically, the breaker has dimensions of 140mm in height, 76.2mm in width, and 76.5mm in depth, with a net weight of 1.034 kg. It is designed for DIN rail mounting, facilitating easy installation in control panels and electrical enclosures. The breaker's insulation voltage is rated at 800V, and it can handle DC operational voltages up to 500V.
