Mounting position is unrestricted, which helps when the panel layout is tight and you need to orient breakers sideways or upside-down.
The energy limiting class 3 means it lets through less energy during a fault — better protection for downstream wiring and loads. Neutral conductor switching (1P+N) disconnects both phase and neutral, which is required in some regional wiring codes and adds isolation safety.
Termination and handling
Screw terminals with a specified torque range of 17.7 to 22.1 lbf·in (2.0 to 2.5 N·m). The breaker is sealable — you can lock the toggle in the off position with a padlock for lockout/tagout. Touch protection is built in, so accidental contact with live terminals during maintenance is less likely.
