The 3VA1196-5EF32-0AB0: Rated at 16 A continuously at ambient temperatures from 40 °C through 55 °C, derating to 15 A at 60 °C through 70 °C. This thermal curve means the breaker holds its full 16 A rating across typical panel internal temperatures; only above 55 °C does a 1 A derate apply, which is relevant if the MCCB sits near transformers or in a tightly packed enclosure. Breaking capacity is 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The TM240 release is thermal-magnetic, meaning it provides both overload (thermal) and short-circuit (magnetic) protection without electronic adjustment. Power loss is 10.6 W maximum — a figure to factor into enclosure thermal calculations when multiple breakers are ganged in a panel.
Auxiliary switch and variant note
This order code includes 2 auxiliary switches (HP design) factory-fitted. The supplied basic switch variant is 3VA11965EF320AA0, which is the core MCCB without auxiliaries. If you need a different auxiliary configuration, the base variant is the reference point for field-installable accessories.
