Product details

What this 3VA2340-5JP32-0AF0 is and what it carries

It's the communication-enabled variant of the base switch 3VA2340-5JP32-0AA0, adding a communication function for remote monitoring or integration into a higher-level control system. Breaking capacity is the headline here: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V.

Above that, it derates linearly: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C.

Dimensions: 248 mm height, 138 mm width, 110 mm depth.

Auxiliary contacts and communication

No undervoltage release or shunt trip is included — those would be added as external modules if needed. The communication function is onboard, so this breaker can report status and trip events over a bus system without an add-on gateway.
