It is rated 20 A at 40 °C and delivers an interrupting capacity of 52.5 kA at 240 V, with derated values at higher voltages: 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V.
At 60 °C and 65 °C it derates to 19 A, and at 70 °C it remains at 19 A. This means the part can be applied in a warm enclosure without losing headroom until the ambient exceeds 55 °C.
The basic switch assembly is order code 3VA10202ED360AA0.
This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time.
The interrupting capacity is 52.5 kA at 240 V.
The depth is 70 mm and the width is 76.2 mm.
