Front-terminal, four-pole design simplifies wiring and services, reducing installation time and ensuring clear fault visibility during maintenance. This configuration is ideal for compact panelboards and motor control centers where accessibility matters. TMF release delivers precise, fast protection with an opening time around 30 ms, supporting selective coordination and enhanced personnel safety in busy control rooms. Rated current of 100 A and rated operating voltage of 600Y/347 V AC (and 500 V DC) enable reliable protection for medium-scale distributions with minimal voltage drop, improving system uptime. Power loss of 7 W per pole under rated conditions reduces energy waste in large installations, contributing to lower operating costs. Compliance and environmental declarations—RoHS, REACH, CMRT, EPD, and CE DoC—support regulatory alignment and sustainable design. Compatibility with busbar 45.5–80 mm², front-terminal connection, and a tightening torque of 6 N·m streamline installation and service in industrial panels.
