The Siemens 3VA5150-4EC36-0AA0 is a 3-pole molded-case circuit breaker designed for system protection. It features an operational current rating of 50A at 40°C, with derated values at higher temperatures.
This circuit breaker operates at a rated voltage of 690V AC and has a maximum DC operational voltage of 500V. Its breaking capacity according to UL 489 is 25kA at 480V, and according to IEC 60947, it is 36kA at 415V and 5kA at 690V. The overcurrent release is of type TM230 with LI protection function.
Designed for DIN rail mounting, this breaker has a mechanical service life of typically 20,000 switching cycles. It is approved by CCC, CE, UL489, and VDE.
Key electrical specifications include an insulation voltage of 800V and a maximum power loss of 12W. The active power loss per pole at rated current and hot operating state is 4W. Electrical endurance varies by voltage and load type, with 8,000 cycles at AC-1 for 380/415V and 4,000 cycles at AC-1 for 690V.
