The thermal-magnetic release holds the full 32 A up to 50 °C; above that the continuous current derates to 30.72 A at 55 °C and 28.8 A at 70 °C, so a panel builder running the breaker near its limit in a warm enclosure should account for the derating curve. ## Selectivity and coordination The 121 kA at 240 V and 75.6 kA at 415 V interrupting ratings mean this breaker can sit at the service entrance or as a main feeder in a panel fed by a transformer with high fault current, without needing an upstream current-limiting fuse. The TM210 release is fixed thermal-magnetic — no electronic trip unit, no adjustable long-time or short-time pickup. That makes coordination with downstream breakers a matter of checking the time-current curve overlap; for a 32 A feeder protecting a panel of 16 A or 20 A branch breakers, the 3VA1032-4ED32-0HH0 typically provides full selectivity up to its instantaneous threshold. The rated insulation voltage of 800 V covers 690 V systems, and the interrupting rating at 690 V drops to 11.9 kA — still adequate for most 690 V motor drives with limited fault current. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a compact footprint for a 32 A MCCB with 121 kA interrupting capacity. A shunt trip release (STL) is built in, with the auxiliary trip coil order code 3VA9688-0BL30 for remote tripping applications.","metaTitle":"Siemens 3VA1032-4ED32-0HH0 SENTRON MCCB, 32 A, 121 kA at 240","metaDescription":"Siemens 3VA1032-4ED32-0HH0 SENTRON molded case circuit breaker, 3-pole, 32 A, TM210 release, 121 kA at 240 V.
