Phoenix Contact 0790530 High Current Connector Bolt OTTA2.5 Series is a high-performance terminal bolt designed for securely terminating crimp terminal rings in electrical applications. Rated to operate at 800V and usable in harsh environments from -60°C to 105°C, this connector bolt ensures safe and reliable connections in industrial and commercial electrical systems.
The bolt termination accepts M4 (6mm² cross-sectional area) or M6 (25mm² cross-sectional area) crimp terminal rings with ease. The innovative hinged cover wings hold the nut securely, allowing for quick, secure connection and disconnection using a screwdriver. These folding wings also provide protection by covering live metal parts, reducing the risk of electrical shock, while enabling marking and identification using supplied marker strips.
Additional design features include spring-loaded, captive spacers that prevent screw loosening caused by vibration, ensuring sustained connection integrity. The universal mounting foot supports installation on both ‘top-hat’ and ‘G’ profile DIN rails for versatile mounting options in electrical control panels.
This product meets rigorous international standards, having approvals such as IECEE CB, LR, UL, VDE, EAC, DNV, and CSA certifications, making it suitable for global industrial, manufacturing, electrical distribution, and power connector applications.
