For installation in assemblies such as panelboards, switchboards, motor control centers, switchgear and machinery control panels, the 210+ electronic trip units are available in two types, LI and LSI. Both versions include a seven-position dial to set current rating (ampacity) of the breaker. The LI version also includes an adjustable instantaneous protection setting. The LSI version includes a short delay setting with magnitude and time delay options to improve coordination when protecting against electrical faults in a system.

Available features on the new electronic trip unit include two dials for simplified setup during installation, including an ampacity dial with seven ANSI ratings on each frame; tighter tolerances on protection curves from thermal magnetic breakers; a status indication light to provide user situational awareness; a test port for secondary injection testing; and a tamper-protection clear cover with a slot for a wire seal.
