The 3VA2010-6HL32-0BA0: The interrupting capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4 kA at 690 V. This SCCR headroom means it can be applied in high-fault-capacity industrial panels without cascading upstream.
Ratings and fit
Rated insulation voltage Ui is 800 V, which covers 480 V and 600 V class systems with margin. The breaker is rated for 100 A continuously up to 50 °C; above that, derate linearly to 85 A at 70 °C. This thermal curve is critical for panel builders calculating fill factor and heat rise inside the enclosure. Dimensions are 181 mm height, 105 mm width, and 86 mm depth. The 105 mm width is the standard 3-pole MCCB footprint for DIN-rail or panel-mount integration; verify gland-plate clearance for the 86 mm depth, which is shallower than many older frame designs. Maximum power loss is 16 W at rated current — a modest figure that simplifies thermal management in a sealed enclosure.
Release and compliance
This MCCB is fitted with an ETU320 electronic overcurrent release (design of the overcurrent release) and an undervoltage release (UVR) as the auxiliary release. The UVR ensures the breaker trips on loss of control voltage — a standard requirement for safety circuits and emergency-stop chains. Mechanical endurance is rated at 20,000 operations (latching endurance). The operating temperature range is -25 °C to +70 °C, with storage from -40 °C to +80 °C. The part carries no auxiliary contact version or communication function — it is a standalone line-protection device.
