Panel integration: the contactor occupies a 70 mm width footprint, 146 mm height, 139 mm depth. The front face is rated IP20 with a cover or box terminal; the terminal area itself is IP00. Pollution degree 3 applies, meaning the contactor tolerates conductive pollution typical of industrial enclosures. Side-by-side mounting is permitted.
Mechanical life typical: 10,000,000 operations. Switching frequencies: up to 900 cycles/hour at AC-1, 400 at AC-2, 1000 at AC-3, 300 at AC-4 (–).
This part is sourced to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The depth is 139 mm.
The solid terminal accepts 2x (0.25... 2.5 mm²).
