This is a switch box primarily designed for disconnecting power circuits and power lines such as motors and control panels. It features a padlock mechanism (can be locked), ensuring safety when operators disconnect and lock it during maintenance. It supports round crimp terminals, which are in high demand in the Japanese market. It complies with IEC60947-3 standards and other international standards as a load switch. It has high dust and water resistance, allowing it to adapt flexibly to installation environments. 【Functions and Features】 - Disconnect switch, disconnector, isolator switch - Compatible with round crimp terminals - High dust and water resistance (IP65/66/67) - Options for resin, iron, or stainless steel boxes - Auxiliary contacts available - Padlock handle (available in red/yellow and black/gray) - Box cannot be opened in the ON position - Supports from 3 poles to 8 poles - Rated operational current up to 315A, series up to 132kW - Compliant with IEC60947-3 standards - Suitable for safety measures in accordance with Article 107 of the Labor Safety and Health Regulations ● For more details, please download the catalog or contact us.

Every year, over 130,000 "caught-in or caught-between" accidents occur according to labor accident statistics. Many of the causes are unexpected restarts during cleaning and maintenance. This book thoroughly explains the lockout-tagout (LOTO) procedures and disconnect switches that serve as fundamental countermeasures, in accordance with the Ministry of Health, Labour and Welfare regulations and the requirements of IEC 60204-1/JIS B 9960-1. The third edition, consisting of 32 pages and over 30 figures and tables, is structured into six chapters: "Legal Obligations and Penalties of LOTO," "Safety Differences between Disconnects and Breakers," "Five-Step Selection Process and Comparison of Terminal Types," "Trap Key Collaboration Achieving Cat4/PLe," and "Implementation Effects in the Food, Automotive, Chemical, and Logistics Industries." It also includes checklists and flowcharts that can be immediately used on-site. Additionally, it features the latest column examining "Are round crimp terminals really essential?" and provides comprehensive navigation from standard compliance to wiring efficiency, using examples from Klaus & Neimer's dustproof and explosion-proof IP66/67 compliant model range. This book is useful for updating safety training materials and preparing investment approval documents for equipment. Download it for free now and elevate your company's safety culture!

This book is a 20-page practical guide systematically summarizing the essential BCP measures for power supply that Japan's manufacturing industry, which frequently faces typhoons, earthquakes, and floods, needs to ensure "operations do not stop due to power outages." Starting with the basics of BCP/BCM, it explains preparations for the most significant obstacle during disasters, "power outages," using abundant illustrations and the latest data (from the Small and Medium Enterprise Agency White Paper and Cabinet Office surveys). Additionally, it clearly organizes the selection points for emergency generators, industrial storage batteries, and high-current cam switches, and includes specifications compliant with IEC60947-3/JIS C8021-3 and layout examples for transfer panels. Furthermore, it introduces four case studies on "construction equipment rental," "building materials manufacturers," "solar power equipment," and "UPS maintenance," presenting the challenges and effects before and after implementation in a quantitative manner. After reading, you will have a concrete action plan that clarifies "which equipment should be prioritized for recovery in your company," "how to shorten power outage recovery times through wiring and switch configurations," and "how to outline a phased implementation procedure that minimizes costs and space." This content is beneficial not only for design and maintenance engineers who are in a hurry to formulate BCP but also for purchasing, production management, and management levels.

With the rapid expansion of direct current applications in renewable energy, EVs, and data centers, the question of "how to choose a DC switch that can be safely disconnected" has become a common challenge for design and maintenance personnel. This document systematically organizes the basics of AC/DC, notable applications, arc discharge countermeasures, and examples of DC switches compliant with IEC60947-3 in 16 pages. It also illustrates the I-V curves by the number of contacts and the test conditions for "disconnection guarantee," allowing for immediate application in field decisions after reading. ● Main Readers Manufacturing industry electrical and mechanical designers / maintenance engineers, renewable energy and power supply personnel, purchasing and management executives ● Expected Outcomes ✓ Understand the essential differences between AC and DC in 30 minutes ✓ Grasp trends and standard requirements in the five major DC markets such as solar power, storage batteries, and railways ✓ Compare the advantages of three patterns of arc suppression and disconnection methods ✓ Quick reference for selecting IP66/67 and DC1000V compliant switches and their implementation effects ✓ Confirm investment recovery images through four case studies in construction machinery, communications, and storage systems As a first step to accelerate decarbonization and BCP measures, download it for free now and share it with your team.
