The Siemens SENTRON 3VA2225-6HN32-0CL0 is a 3-pole molded case circuit breaker rated for 250 A continuous at 40 °C, with a maximum interrupting capacity of 242 kA at 240 V. This is a line-protection design (not a motor-protection breaker), so it's sized for feeder or main service entrance duty.
The case measures 105 mm wide by 181 mm tall by 86 mm deep — a standard SENTRON 3VA2 frame size that fits the same mounting footprint as other 250 A MCCBs in the family. That 86 mm depth (3.39 in) is the dimension that matters when the gland plate or enclosure door clearance is tight. The breaker ships with the basic switch 3VA2225-6HN32-0AA0 as the supplied switching element; the order code suffix -0CL0 adds the specific UVR and auxiliary contact configuration.
