The Siemens 3VA1025-2ED36-0CH0 is a 3-pole IEC frame 100 molded case circuit breaker (MCCB) rated at 25 A continuous, with a fixed thermal-magnetic TM210 trip unit. The short-circuit pickup is fixed at 12.8 times In (320 A), so motor inrush or transformer magnetizing current won't cause nuisance trips on start-up. The clamp-type terminals accept copper conductors without lugs — common in panel builds where speed and a clean wireway matter.
Integration notes
The undervoltage release coil draws a continuous holding current when energized; verify the control transformer VA budget before wiring. If the coil drops out below roughly 85% of rated voltage, the breaker trips — that's the intended behavior for undervoltage protection, not a fault.
