Siemens 5SY4 Series Miniature Circuit Breaker, 32A Current, 10kA Breaking Capacity - 5SY4332-8

This miniature circuit-breaker provides overcurrent protection for three-phase installations and is intended for DIN-rail mounting in industrial and infrastructure settings. It is suitable for alternating and direct voltage systems, offering multi-pole switching and touch protection while operating across standard 50/60 Hz supplies.

Features and Benefits:

• Type D tripping characteristic for high inrush current handling
• Rated for 400 V AC supply enabling three-phase system use
• 60 V DC rating for compatibility with low-voltage DC circuits
• 10 kA breaking capacity per EN 60898 for domestic/industrial faults
• IP20 protection class allowing safe handling with conductors fitted

Applications

• Suitable for motor-start circuits with high inrush currents
• Used with distribution boards in industrial installations
• Ideal for mixed AC/DC power systems requiring Compact protection
• Can be used for three-pole isolation on DIN-rail panels

What conductor sizes can be connected to this device?

It accepts solid and stranded conductors from 0.75 mm² up to 35 mm² and finely stranded cores up to 25 mm².

How should torque be applied to the terminals during installation?

Tighten screw terminals between 2.5 N·m and 3.5 N·m to ensure secure connections.

What environmental conditions affect its operating limits?

It operates between -40 °C and 70 °C and tolerates varying relative humidity up to specified maxima at elevated temperatures.

What mechanical endurance can installers expect from the unit?

Typical mechanical life is approximately 10,000 operating cycles under normal use.

How Compact is the product for panel-design considerations?

The device occupies 3 modular width units and is designed for DIN-rail fastening for space-efficient mounting.
