The Siemens 3VA5145-6EC41-0AA0 is a 4-pole molded-case circuit breaker from the SENTRON series, designed for system protection applications. This breaker operates with a maximum rated operational voltage of 690V AC and 600V DC. It features a permanent rated current (Iu) of 45A at 40°C, with adjustable overload protection (Ir=45A) and fixed short-circuit protection (Ii=5...10 x In).
With a breaking capacity of 150kA at 240V and 65kA at 480V according to UL 489 standards, and 70kA at 415V according to IEC 60947, this circuit breaker ensures reliable protection. It is built with a mechanical service life of typically 15,000 switching cycles and an electrical endurance of 8,000 cycles at 380/415V.
The breaker is suitable for HACR Type applications and mounts via DIN rail. It features a TM230 overcurrent release with LI protection function. The N-conductor is unprotected and not upgradeable. Power loss is a maximum of 10.2W, with 3.4W active power loss per pole under hot operating conditions.
