The TM210 thermal-magnetic trip unit provides line protection; the FTFM designation indicates a fixed thermal and fixed magnetic setting, so no field adjustment of the trip curve is possible — the part ships with the settings locked at the factory. The breaker includes a factory-installed shunt trip accessory wired to the left side, rated 208–277 V AC 50/60 Hz and 220–250 V DC. This is the remote-trip coil, not an undervoltage release; it requires a sustained control voltage to hold the mechanism closed and trips the breaker when the control voltage is removed or interrupted. For panel integration, the neutral conductor is unprotected (solid neutral) and terminates via clamp connection — the same clamp style used on the phase poles. The fixed-trip configuration and factory-fitted shunt trip mean the order code must match the BOM exactly — field conversion from a base breaker is not practical.","metaTitle":"Siemens 3VA1025-3ED46-0KD0 Circuit Breaker, 25A, 25kA @ 415V","metaDescription":"Siemens 3VA1025-3ED46-0KD0 IEC 4-pole circuit breaker, 25A, 25kA breaking capacity at 415V AC.
