This Siemens 3VA5225-1MU36-0AA0 is a 3-pole molded-case circuit breaker from the 3VA5 series, specifically designed for starter protection applications. It operates at a rated insulation voltage of 800V and an operating voltage of 690V AC.
The breaker offers a high breaking capacity, with a maximum short-circuit current (Icu) of 200 kA at 240V and 110 kA at 415V. The operating short-circuit current (Ics) is also 200 kA at 240V and 110 kA at 415V. Its short-circuit making capacity (Icm) is 440 kA at 240V and 242 kA at 415V.
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of 8,000 cycles at 380/415V and 4,000 cycles at 690V, this circuit breaker is built for durability. It has a maximum power loss of 58W and an active power loss per pole of 19.33W in hot operating state.
The unit features front connections with circular conductor terminals on both sides, supporting conductor cross-sections from 6 AWG to 350 kcmil. It is designed for DIN rail mounting and has dimensions of 185mm height, 105mm width, and 83mm depth. An optional motor drive accessory is available.
