Trip release can be reset manually after fault clearing.
Accepts main circuit conductors up to 2x 25 mm² or a single 35 mm² solid or stranded per terminal; screw-type terminals are standard. Required clearances for proper arc and thermal management: 50 mm upward and downward from the breaker body, 10 mm at the sides. Dimensions: 149 mm depth, 55 mm width, 140 mm height. Connector pitch on main terminals is M6.
Depth 149 mm, width 55 mm, height 140 mm. Terminal studs are M6.
No. This is a motor protection circuit breaker for power distribution; it cannot serve as a PLC controller or I/O module.
