Siemens 3VA2216-5HN42-0AA0

The 3VA22 4P Circuit Breaker is designed for low voltage applications, featuring a medium breaking capacity classified as M. It operates at a rated voltage of 690V, with a short-circuit breaking capacity of 55kA at 415V. The device is equipped with an ETU350 electronic trip unit for precise overload and short-circuit protection, adjustable between 63A and 160A.

With dimensions of 5.5 inches in width, 7.1 inches in height, and 4.2 inches in depth, this built-in device is suitable for DIN rail mounting. It supports connection via a lug terminal/nut keeper and provides front-side electrical connection. The operational temperature range extends from -25 °C to 70 °C, ensuring functionality in diverse environments, while the device maintains an IP40 protection rating.

Notably, the circuit breaker has a mechanical service life of approximately 25,000 operating cycles and can handle electrical endurance up to 12,000 cycles under AC-1 conditions at 415V. The absence of integrated earth fault protection and under voltage release indicates a straightforward design focused on line protection.

This unit is compliant with IEC standards and features a low global warming potential, emphasizing efficient environmental performance.
