Siemens 3VA2 Series Circuit Breaker, 400A Current, 690V Rated AC Voltage - 3VA2340-5HL32-0AA0

This circuit breaker provides three-pole protection for line circuits in industrial installations. It is a moulded-case device designed for thermal-magnetic and electronic overcurrent protection with adjustable long-time and instantaneous settings, suitable for distribution and motor-protection tasks up to 690V AC. The unit is intended for front-terminated connection and includes options for motor drive accessories.

Features and Benefits:

• 55kA breaking capacity delivers high short-circuit interruption performance
• Adjustable Ir160A to 400A enables tailored overload protection
• Ii600A to 4000A setting range gives scalable short-circuit response
• 800V insulation rating supports higher voltage system resilience
• 6 000 electrical cycles at 380/415V offers prolonged switching life

Applications

• Used for line protection in industrial power distribution
• Suitable for motor feeder protection with adjustable trips
• Ideal for switchboard integration requiring front terminals
• Used with flat-bar connections in Compact installations
• Suitable for environments needing VDE EAC CCC approvals

What Terminal type does it use for the main current circuit?

It uses front terminals with nut keeper kit for secure connections.

How does ambient temperature affect the rated current?

Rated current remains 400A up to 50°C then derates progressively to 340A at 70°C.

What are typical electrical endurance figures at rated voltages?

Electrical endurance is 6 000 cycles at 380/415V and 4 200 cycles at 690V.

What protection functions are not included in the Basic unit?

It does not include undervoltage release, voltage trigger, trip indicator or earth-fault monitoring.

What ingress protection applies to the front of the device?

The front face has an IP40 protection rating.
