(Note 1) The rated Circuit Breakers capacity is 1.5/1 kA for parts with 5 A rated current.
(Note 2) The customer must provide the mounting screws. Use SW-PW-P pan-head screws (M4 × 0.7 × 50).
(Note 3) Only included when an alarm switch (AL) is provided (excluding SHT + AL).
(Note 4) Can install surface plate without tightening nuts from the back (The customer must provide the mounting screws M5 × 0.8 × 30). Here, terminal screws can be tightened from the back of the breaker.
(Note 5) The terminal structure allows back surface wiring.
