The 3VA1020-2ED32-0HH0: Rated insulation voltage Ui of 800 V means the breaker's internal clearances and creepage are designed for 800 V line-to-line systems, so it can be applied on 480 V, 600 V, and 690 V networks without derating the insulation. The 20 A continuous rating holds flat through 50 °C; above that it derates to 19.2 A at 55 °C and 18 A at 70 °C — relevant for a sealed enclosure with limited convection. Breaking capacity at 415 V (32 kA) is the figure that governs most European 400 V industrial panels; the 52.5 kA at 240 V covers North American 240 V delta or split-phase services. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a compact 3-pole MCCB footprint that fits standard SENTRON panel-mounting patterns. Mechanical endurance is 15 000 cycles, adequate for a line-protection breaker that sees infrequent operation.
Auxiliary and Trip Configurations
The shunt trip (STL) allows remote tripping via a control voltage; the undervoltage release is not fitted on this order code. No communication function, phase failure detection, or ground fault monitoring is integrated — this is a straightforward thermal-magnetic line-protection breaker with basic remote-trip capability.
