Frequently Asked Questions

What is the SIEMENS 5SY62027 supplementary protector used for?

The SIEMENS 5SY62027 is a C-curve, 2-pole supplementary protector rated at 2 A for overcurrent protection in industrial control panels, HVAC equipment, and lighting circuits. It mounts on a DIN rail and is UL1077 listed for branch-circuit protection up to 400V AC.

What are the specifications of the SIEMENS 5SY62027?

The SIEMENS 5SY62027 is a 2 A, C-curve supplementary protector with a max. AIR rating of 5kA at 400V AC. It has a screw-clamp terminal connection, is rated for 400V AC only (not DC), and is part of the 5SY6 series. It is not rated for DC voltage.

Where to buy the SIEMENS 5SY62027 worldwide?

You can source the SIEMENS 5SY62027 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this 5SY6 series supplementary protector.

How to install the SIEMENS 5SY62027 supplementary protector?

Install the SIEMENS 5SY62027 by snapping it onto a standard 35 mm DIN rail. Ensure the circuit is de-energized, then connect phase and load wires to the screw-clamp terminals per the torque specs in the datasheet. The C-curve trips between 5x and 10x rated current for moderate inrush loads.
