Siemens 5SY4 Series Miniature Circuit Breaker, 16A Current, 3P Poles - 5SY4316-6


This miniature circuit breaker provides three-pole overload and short-circuit protection for AC and DC systems. Designed for DIN-rail mounting in industrial and infrastructure installations, it operates at up to 400 V AC and is rated for 60 V DC. The device employs a Type B tripping characteristic suitable for circuits with mainly resistive loads and is intended for installations where compact, modular protection is required.

Features and Benefits:


• 10 kA breaking capacity for EN 60898-1 provides effective fault interruption
• Type B tripping characteristic protects predominantly resistive circuits
• 16 A rated current supports common distribution circuits
• Screw terminals accept up to 35 mm² conductors for secure connections
• IP20 protection ensures finger-contact safety in panel environments

Applications


• Suitable for distribution boards in industrial installations
• Ideal for protecting lighting and socket circuits
• Used with single- and multi-phase AC systems up to 400 V
• Can be used in DC control circuits up to 60 V
• Suitable for infrastructure projects requiring modular protection

What mounting method is required for installation?


It is designed for DIN-rail mounting allowing Rapid Snap-on installation.

How does the device handle thermal stress at elevated temperatures?


Operational current is derated with temperature: 15.23 A at 40 °C down to 13.57 A at 60 °C.

What conductor types and sizes can be connected?


Solid, stranded and finely stranded conductors can be used from 0.75 mm² up to 35 mm², with core-end processing up to 25 mm².

What mechanical endurance can be expected from switching operations?


The breaker is specified for a typical mechanical service life of 10,000 operating cycles.

Which approvals and standards apply to this product?


It meets IEC/EN 60898-1 and IEC/EN 60947-2 and holds UL1077 recognition.

Standards

Standards: EN 60898; DIN VDE 0641; Part 11; IEC 60898
