A company dedicated to safety

KATKO, an industry-leading Finnish manufacturer, produces an extensive range of quality standard approved isolators, safety switches and accessories.

KATKO’s standard isolator and safety switches range from 10A to 630A and up to 1600A for special applications. Built for specialist markets including food production, air quality, heavy industry, hazardous and corrosive areas (ATEX/RINA certified), renewable energy and power distribution.

Safety in the workplace

Every employer wants to protect its workforce from the risk of electrical malfunction and unauthorised tampering with potentially hazardous electrical equipment and systems. Yet the old-fashioned isolator switches still used in many working environments undermine compliance with safety standards and pose risks to the safety and lives of employees.

Responsible institutions are switching to KATKO Safety Switches with their integrated interlocking mechanism which makes them impossible to override or bypass in the ‘PADLOCKED OFF’ position. KATKO Safety Switches have a full range of accreditations, including ATEX, FI, KEMA, CE, UL Listed, BBJ, ESC, RINA, and IEC, making them the switches of choice for factories, public and commercial buildings, hospitals, and hotels all over the world.

Easy installation

KATKO Safety Switches are easy and time-saving to install. Large terminal capacity is standard, and with handle and screws retained in the cover and fixing dimensions moulded into the base, handling could not be simpler. The plug-in switch is easy to remove and replace for quick cabling. With smaller switches, the switch can simply be ‘unplugged’ from the base for ease of wiring and then plugged back in. The auxiliary contacts simply snap onto the top of the switch and can be retrofitted without disturbing the main wiring. The switches include knockouts at the top and bottom for ease of cabling. Neutral and earth terminals are fitted as standard inside the enclosure of the 3-pole switch, and an earth terminal is fitted as standard in the 4-pole switch. The fixing centres are marked on the back of the switch housing.
