The Siemens 3VA1225-6EF32-0BH0 is a 3-pole IEC frame 250 molded case circuit breaker from the 3VA1 series, rated for line protection with a TM240 thermal-magnetic trip unit. Breaking capacity class H delivers Icu=70kA at 415 V AC — enough to handle high-fault-current scenarios typical in industrial main feeders or large motor branch circuits without cascading upstream.
The breaker includes a nut keeper kit for secure panel mounting, plus an undervoltage release (UVR) at 24 V DC for remote trip on loss of control voltage. Two auxiliary switches (HQ) and one trip alarm switch (HQ) provide status feedback to a PLC or annunciator panel — useful for fault isolation in a motor control center or distribution board.
