3VA4190-4ED34-0AA0

The Siemens SENTRON series 3VA4190-4ED34-0AA0 molded case circuit breaker is engineered for versatility in electrical distribution systems. This unit supports a continuous current rating of 90 Amperes and can function effectively within a rated system voltage of 690 Volts AC. The circuit breaker is structured for 3-phase applications, making it valuable in multiple industrial settings.

One of its notable features is the adjustable response delay time, which is set at just 1 millisecond, allowing for quick reaction to fault conditions. The device showcases a power loss of 5.9 Watts at rated continuous current, while the maximum power loss can reach up to 17.7 Watts during operation.

This circuit breaker provides substantial breaking capacities, with figures detailed as follows: 65 kiloamperes at 240 Volts AC, 25 kiloamperes for 277/480 Volts AC, and 14 kiloamperes at 347/600 Volts AC. For overcurrent protection, it includes both long-time and instantaneous trip functions (LI).

The 3VA4190-4ED34-0AA0 supports conductor cross-sections ranging from 8 to 3/0 AWG, allowing for flexibility in wiring setups. This device features a terminal connection of load side lugs for easy installation and connectivity. Highly rated for performance, it operates efficiently across 50 to 60 Hertz, ensuring broad compatibility across varying frequency applications. The protection class is designated as IP40 for the front part of the breaker, which provides adequate defense against dust and accidental contact.
