MCCB for high-fault panel positions
The line protection version is what you spec for feeder or main breaker duty in a panel, not for motor branch-circuit protection. That UVR coil will drop the breaker if control voltage is lost — a common requirement for emergency-stop circuits or safety interlock schemes.
Interrupting ratings across voltages
The interrupting capacity drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at both 500 V and 690 V.
Current derating and ambient temperature
The 32 A rating holds steady up to 50 °C ambient; at 60 °C it derates to 31 A, and at 70 °C to 30 A. That's minimal thermal drift for a thermal-magnetic MCCB — the TM220 release is well-compensated.
The breaker is 3 inches wide (about 76 mm) and 130 mm tall — standard MCCB footprint for a 3-pole frame at this rating. The IP40 front protection means it's suitable for a closed panel; no additional sealing is required for normal indoor environments.
