It supports a maximum continuous current of 400A and is suitable for voltage levels up to 1000 VDC, offering exceptional performance and peace of mind.

Key Features:

• High peak current carrying capability: Ensures superior performance in extreme conditions.
• Compliance with industry standards: Guarantees quality and reliability.
• Advanced breaking metrics:

• • 1000V/15000A/15μH
  • 800V/20000A/13μH
  • Provides robust protection under high-voltage scenarios.

• Efficient cooling requirements: The customer’s cooling system must maintain terminal connection point temperatures below +125°C.
• Long-term and short-term current capabilities: With a 150mm² busbar:

• • Long-term continuous current: 400A
  • Short-term fast charging: 450A for 40 minutes or 600A for 10 minutes

• Ingress protection: Ensures durability and safety before and after triggering.

The device features precise triggering conditions, with a triggering circuit resistance of 2±0.2Ω and specific current and pulse slope requirements for reliable operation.

It operates within a temperature range of -40°C to 85°C (derating required at higher temperatures) and can be stored at -40°C to 65°C with up to 90% relative humidity.
