Siemens 5SY4 Series Miniature Circuit Breaker, 4A Current, 400V Rated AC Voltage - 5SY4204-8
This miniature circuit breaker provides overcurrent protection for AC and DC installations, delivering selective interruption for two-pole circuits on a DIN rail. Designed for industrial and infrastructure environments, it operates at up to 400V AC or 60V DC and uses a Type D tripping characteristic suitable for circuits with high inrush currents.
Features & Benefits
• 10kA breaking capacity for EN60898-rated short-circuit protection
• Rated current 4A to protect low-current branch circuits
• Type D tripping to tolerate high motor or transformer inrushes
• Screw terminals with 2.5 to 3.5N·m torque for secure conductor connections
• 2-pole configuration enabling simultaneous disconnection of both conductors
• IP20 touch protection while mounted with conductors connected
• Rated current 4A to protect low-current branch circuits
• Type D tripping to tolerate high motor or transformer inrushes
• Screw terminals with 2.5 to 3.5N·m torque for secure conductor connections
• 2-pole configuration enabling simultaneous disconnection of both conductors
• IP20 touch protection while mounted with conductors connected
Applications
• Suitable for motor starter protection in factory automation panels
• Ideal for transformer secondary circuits with high inrush currents
• Used for selective protection in distribution boards of industrial sites
• Can be used for DC control circuits up to 60V in machinery cabinets
• Ideal for transformer secondary circuits with high inrush currents
• Used for selective protection in distribution boards of industrial sites
• Can be used for DC control circuits up to 60V in machinery cabinets
What conductor sizes can be connected to the device?
Solid and stranded conductors from 0.75mm² up to 35mm² are supported, with finely stranded conductors accepted up to 25mm²
AWG range is 18 to 4.
How does ambient temperature affect the rated current?
The nominal 4A rating varies with temperature: approximate operational currents are 3.76A at 40°C, 3.5A at 50°C, 3.36A at 55°C and 3.22A at 60°C.
What mechanical endurance can be expected from the breaker?
The device typically endures around 10,000 mechanical operating cycles under normal use.
Which installation positions and mounting methods are possible?
It can be mounted in any orientation on a DIN rail using a quick assembly system and occupies two modular width units.
What environmental limits apply during storage and operation?
Operational ambient range is −40°C to 70°C and storage range is −40°C to 75°C, with vibration resistance per IEC 60068-2-6.
