The Siemens 3VA5140-5ED11-0AA0 is a 1-pole molded-case circuit breaker from the 3VA5 series, designed for system protection applications. It features a rated operational current of 40A at 40°C, with derating at higher temperatures. The breaker provides a breaking capacity of 35kA at 277V according to UL 489 standards and 5kA at 415V according to IEC 60947 standards.
This circuit breaker is built with a TM210 overcurrent release and offers LI protection function. It has a maximum rated operational voltage of 415V AC and 125V DC, with an insulation voltage of 500V. The mechanical service life is typically 15,000 switching cycles, and electrical endurance varies by voltage and load type, with 8,000 cycles at AC-1 for 380/415V.
Designed for DIN rail mounting, the unit has dimensions of 140mm height, 25.4mm width, and 76.5mm depth. It operates with a maximum power loss of 3.4W. The adjustable response current for short-circuit protection (Ii) ranges from 400A to 400A.
