Product Description This comprehensive security switch is different from ordinary 80N switch, but also from ordinary lighting integrated security, it is our coal production for many years through the research, the 80N certain power switch and lighting protection devices combined, given the extension of the decades old equipment new life. Product attributes 1, the comprehensive security portfolio as mine new products, and access to national utility model patent certificate. Patent number: ZL2006200113585. 2, the domestic original lighting protection devices and ordinary 80N starters combined mining combination switch devices. Comprehensive security portfolio not only saves installation space, but also save the cost of production, greatly improving production efficiency. 3, the use of lighting circuits for the pilot to control the starter, so that the illumination signal circuit must first be turned on using the starter section, in full compliance with underground procedures, to ensure the safe use of electricity, to prevent illegal operations radically. 4, the use of advanced self-test circuits, reasonable and efficient protection features make the device more secure. 5, while providing two voltage levels of 127V and 36V lighting or signaling load, and have insulation monitoring and overload protection, greatly improving the safety of equipment, flexibility and adaptability. 6, using the pull-mounted internal chassis, easy to operate, easy to maintain.
