The Siemens SENTRON 3VA5220-1MH36-0AA0 is a 3-pole molded-case circuit breaker designed for starter protection applications. It features a 200A operational current rating across a wide temperature range from 40°C to 70°C and a rated insulation voltage of 800V with an operating voltage of 690V AC.
This circuit breaker has a high breaking capacity, with a maximum short-circuit current (Icu) of 200 kA at 240V and 110 kA at 415V. It also boasts a significant short-circuit making capacity (Icm) of 440 kA at 240V and 242 kA at 415V. The mechanical service life is rated at a typical 20,000 switching cycles, with electrical endurance varying based on voltage and current conditions.
Designed for front connection with circular conductor terminals on both sides, it accommodates stranded conductors from 6 AWG to 350 kcmil. The unit has a compact mechanical design with dimensions of 185mm height, 105mm width, and 83mm depth. It is suitable for DIN rail mounting.
This breaker is UL 489 listed and is considered HACR Type. It operates without overload protection, focusing on short-circuit protection with an adjustable Ii range of 6 to 12 times the nominal current.
