Siemens 3VA2 Series Molded Case Circuit Breaker, 400A Operational Current, 690V Rated AC Voltage - 3VA2340-6HL42-0AA0

This moulded case circuit breaker provides line protection for industrial AC systems up to 690V and is configured with four poles for comprehensive multi-conductor protection. It employs an ETU320 overcurrent release with LI protection to deliver adjustable overload and short-circuit settings and is intended for front-terminated installations where reliable switching and high endurance are required.

Features and Benefits:

• 85kA breaking capacity delivers robust fault interruption
• Adjustable Ir 160A to 400A enables tailored overload protection
• Ii setting range 600A to 4000A supports selective short-circuit response
• Neutral protection configurable OFF/50%/100% permits system flexibility
• Front Terminal nut keeper aids secure conductor connections

Applications

• Suitable for main distribution boards in industrial plants
• Used for three-phase motor feeder protection
• Ideal for power centres requiring high interrupting capacity
• Can be used in installations needing adjustable NEUTRAL protection
• Suitable for retrofit where front-connected breakers are required

What is the expected electrical endurance under rated conditions?

It achieves 6000 operating cycles at 380/415V in AC-1 duty and 4200 cycles at 690V.

How does temperature affect the rated operational current?

The operational current remains 400A up to 55°C then reduces progressively to 340A at 70°C.

What are the short-circuit making capacity values?

Peak making capacity reaches 242kA at 240V and 187kA at 415V for dynamic fault conditions.

Which approvals support use in varied regulatory regions?

It carries CCC, CE and EAC approvals for cross-market acceptance.

What is the typical mechanical service life?

The device is specified for around 20 000 mechanical operating cycles.
