Siemens 3VA4190-6ED34-0AA0 Molded Case Circuit Breaker

Siemens 3VA4190-6ED34-0AA0 is a three-pole molded-case circuit breaker (MCCB) in the Siemens 3VA4 UL frame family, designed for branch-circuit protection in commercial and light-industrial power systems. It carries an In rating of 90 A with a thermal-magnetic TM210 trip unit (FTFM) and fixed short-circuit protection Ii = 10 x In, offering reliable coordination for overloads and faults. The device provides a 65 kA short-circuit interrupting capacity at 480 V, making it suitable for feeders and equipment protected against high fault currents. It uses lug-type load termination (LD LUG) and weighs about 0.743 kg, with a compact form factor that fits standard switchboards and panelboards. The 3P configuration (three-pole) supports balanced three-phase protection for motors, transformers, and distribution networks, and the HACR-type rating indicates suitability for HVAC installations under UL 489 requirements. Rated for AC operation up to 480 V line-to-line, this MCCB delivers dependable performance in environments where 90 A nominal load and 65 kA fault clearance are appropriate, while maintaining robust mechanical endurance and electrical endurance across thousands of switching cycles. Siemens’ 3VA4 family is recognized for its precise protection, durable construction, and straightforward field installation, making the 3VA4190-6ED34-0AA0 a precise choice for protecting critical loads in modern electrical distributions.
