The introduction of the disconnection switch and trap key system allows for the implementation of the highest safety level category 4 and performance level e in compliance with ISO safety standards without complex calculations. ■ A must-see for those involved in safety measures and occupational health with the following challenges! - Is there a safety measure that ensures on-site users always take "correct actions"? - Are there safe and simple risk measures that do not require tedious information gathering or complex calculations? If you have such concerns... Consider safety measures that can be easily implemented with the disconnection switch + trap key system. ■ Benefits of the disconnection switch + trap key system Access to hazardous areas is only possible through predetermined procedures, and the key can only be returned to resume power supply when the protective fence/door of the hazardous area is closed, making it more reliable and safe than lockout or tagout. ■ Three points of the disconnection switch + trap key system (1) Easily achieve category 4, PLe (2) Anyone can enter hazardous areas with the assurance that the hazard source is isolated (3) No electrical wiring is needed, making retrofitting easy. Applicable in explosion-proof areas as well.

"Power outages" can occur at any time due to earthquakes, typhoons, and other factors. Recently, as part of business continuity planning (BCP), we often hear from clients asking about the actual measures taken to prevent power outages in factories. For those who have postponed power outage measures due to reasons such as "cost constraints," we would like to introduce the "Emergency Manual Power Switch" from Klaus & Neimer, a specialist manufacturer of safety switches. This product allows for the switching of power and machinery with just one switch. It is low-cost and does not require complicated wiring checks, making it easy to install. Additionally, since it is manually switched, it is immediately clear whether you are using "normal" or "emergency" power, helping to reduce the occurrence of mistakes. We are currently offering a carefully explained BCP strategy handbook that emphasizes the importance of "securing power." It is perfect for those who are considering power outage measures. Please feel free to download and take a look.

Accidents caused by being caught or entangled account for 27% of labor accidents in the manufacturing industry. Every year, injuries and fatalities occur due to unexpected movements of equipment and facilities or unanticipated restarts. Various measures, including lockout/tagout, have been implemented to prevent such accidents. One of these measures is the "disconnect switch," which ensures that the power supply can be reliably cut off. However, selecting the appropriate product for the site requires correct knowledge. The handbook "Knowledge and Safety Measures for Disconnect Switches" by industrial switch manufacturer Klaus & Naimer covers the necessary knowledge for selecting disconnect switches. The latest edition explains the following content: [Contents] ■ What are lockout and tagout? ■ What is a disconnect switch? ■ Differences from regular switches and breakers ■ How to select a disconnect switch ■ Case studies *Please be sure to check the handbook from the "PDF Download" link below!
