Siemens 5SY4 Series Miniature Circuit Breaker, 2A Rated Current, 400V Rated AC Voltage - 5SY4102-8

This miniature circuit-breaker provides single-pole overcurrent protection for AC and DC installations, designed for DIN‑rail mounting in infrastructure and industrial environments. It operates with a Type D tripping characteristic and supports 50/60 Hz supply systems, offering touch‑protected screw terminals and halogen‑free construction for standard electrical distribution applications.

Features and Benefits:

• 10 kA breaking capacity ensures secure fault interruption
• 60 V DC rating permits use in low-voltage DC circuits
• Type D tripping characteristic clears high inrush currents
• IP20 protection delivers Basic contact prevention with conductors connected
• 18 mm width enables Compact multi‑module panel layouts

Applications

• Suitable for industrial motor-start protection
• Ideal for mixed AC/DC control panels
• Used with DIN‑rail distribution assemblies
• Can be used for infrastructure electrical distribution
• Suitable for installations requiring UL1077‑approved components

What current at elevated temperatures should be expected?

Rated operational current is 2 A under standard conditions with reduced values at higher ambient temperatures, down to 1.7 A at 60 °C.

What conductor sizes can be terminated with the screw terminals?

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

How many mechanical operations is the device specified for?

Mechanical service life is typically 10,000 operating cycles.

What are the torque requirements for Terminal tightening?

Tightening torque ranges from 2.5 N·m to 3.5 N·m (22 lbf·in to 31 lbf·in).

What environmental temperature range can it tolerate in operation?

Operational ambient temperature ranges from -40 °C up to a maximum of 70 °C.
