This Siemens 3VA5190-5EC32-1AA0 is a 3-pole molded-case circuit breaker designed for system protection. It operates at a rated voltage of 690V AC and has a nominal current rating of 90A at 40°C, with derated values at higher temperatures.
The circuit breaker offers a breaking capacity of 35kA at 480V, 85kA at 240V, and 18kA at 600Y/347V. It utilizes a TM230 trip unit with LI protection function, featuring fixed overload protection (Ir=90A) and adjustable short-circuit protection (Ii=5...10 x In).
With a mechanical service life of typically 20,000 switching cycles and electrical endurance ratings of up to 8,000 cycles, this breaker is built for durability. It has a maximum power loss of 21.4W and an active power loss of 7.13W per pole under hot operating conditions. The dimensions are 140mm in height, 76.2mm in width, and 76.5mm in depth. It is designed for front connection with a nut keeper kit terminal type and supports conductor cross-sections from 12 x 1 mm up to 17 x 6.5 mm.
This breaker is UL489 listed and HACR Type approved. It is suitable for DIN rail mounting and features a rocker lever actuator. The device construction is a built-in type with fixed built-in technique.
