Siemens 3VA5 Series Circuit Breaker, 300A Current Rating, 65kA Breaking Capacity - 3VA5330-6EF41-0AA0
This circuit breaker provides overcurrent protection and switching for industrial electrical systems, designed for fixed-panel installation in three-phase networks up to high voltages. It combines a thermal‑magnetic trip arrangement with four‑pole switching to manage both AC and DC supply environments commonly encountered in automation and heavy electrical installations.
Features and Benefits:
• 300A rating enables sustained high-current operation and load management
• 65 kA breaking capacity ensures safe interruption of short-circuit faults
• Type H trip characteristic allows discrimination in selective protection schemes
• Thermal‑magnetic operation offers combined overload and short‑circuit response
• Rated for 690V AC and 600V DC operation for versatile system compatibility
• 65 kA breaking capacity ensures safe interruption of short-circuit faults
• Type H trip characteristic allows discrimination in selective protection schemes
• Thermal‑magnetic operation offers combined overload and short‑circuit response
• Rated for 690V AC and 600V DC operation for versatile system compatibility
Applications
• Suitable for distribution panels in industrial automation plants
• Ideal for motor control centres requiring selective protection
• Used with high‑voltage switchgear in manufacturing facilities
• Can be used for DC‑fed systems in energy storage and conversion setups
• Used for electrical distribution in marine or offshore installations

What mounting arrangement is required for installation?
It is designed for fixed mounting within switchboards or enclosures and requires secure attachment points for panel integration.
How many poles does it switch and why is that useful?
It switches four poles, enabling simultaneous isolation of all conductors including the NEUTRAL where needed for complete circuit disconnection.
What approvals indicate suitability for international deployments?
It carries a range of approvals from recognised bodies, supporting use across different regulatory regions.
How does the trip mechanism respond to sustained overload versus instantaneous fault?
The thermal element provides time‑dependent overload tripping, while the magnetic element triggers Rapid interruption for high‑magnitude short circuits.
What Terminal configuration is provided for connection?
The product is supplied without fitted Terminal accessories, allowing installers to select compatible termination hardware.
