Product Identification and Core Ratings
The main power circuit accepts stranded conductors from 16 to 70 mm², and the auxiliary circuit accepts solid or stranded conductors from 0.5 to 4 mm² depending on the number of conductors per clamp.
Mounting is by screw fixing, with the contactor designed for a vertical mounting surface. It can be rotated ±90° or tilted ±22.5° forward and backward, offering flexibility in panel layout. The overall dimensions are 172 mm height, 120 mm width, and 170 mm depth, which defines the panel space required for a single unit. These limits govern both the panel ambient conditions and the logistics environment.
Switching Performance and Duty Ratings
The contactor is rated for different switching frequencies depending on the duty category: AC-1 (resistive) at 800 operations per hour, AC-2 at 400 ops/h, AC-3 (motor start/run) at 1000 ops/h, AC-3e at 1000 ops/h, and AC-4 (plugging/inching) at 130 ops/h. The arcing time is 10-15 ms, and the operating time (both AC and DC) is 40-60 ms. Mechanical life typically 10,000,000 operations.
