Overload behaviour

PULS Overload Design™: No switch-off at
overload/short-circuit, instead: up to 1.5 ⋅ Irated.
So you need no oversizing to start awkward
loads.

Protection

Unit is protected against (also permanent) shortcircuit, overload and open-circuit.

Design details – for your advantage:• All terminals are easy to reach as mounted on the front panel.
• Input and output are strictly apart from each other (input below, output above) and so cannot be mixed up• Mounting and connection do not require any screwdriver→ Easy, quick, durable and reliable installation
