K-ELECTRIC 353063 4-pólový 63A DIN lištový prepínač záťaže 400V AC

In industrial control panels and building service distribution boards, maintaining supply continuity during source changeover is critical. The K-ELECTRIC 353063 is a 4-pole load transfer switch rated at 63 A, engineered for manual switching between two independent power sources. Its DIN rail mounting and compact 4-module width make it a practical choice for electricians and panel builders integrating backup generator or secondary feeder changeover in commercial and light industrial installations.

Why choose it

The switch's robust construction and clear three-position operation allow safe, unambiguous source selection. Its high insulation voltage and impulse rating provide reliable isolation in demanding electrical environments. The compact DIN rail design saves space in distribution boards while simplifying installation and wiring.

Ideal use cases

• Manual transfer between utility and backup generator in small commercial buildings
• Changeover between two feeders in industrial control panels
• Isolation and source selection in HVAC, pumping, and lighting distribution circuits
• Retrofit projects requiring a DIN rail mountable 63 A transfer switch

Good to know

The switch is intended for manual operation and does not include automatic transfer logic. It should be installed in an enclosure providing appropriate protection against accidental contact. Always verify local wiring regulations and ensure the connected load does not exceed the rated current.
