At 45 mm wide, 58 mm tall, and 73 mm deep, it fits into tight panel layouts where space on the DIN rail is at a premium.
The contactor is rated for AC-3 switching duty at up to 750 operations per hour — that's the mechanical life you can expect when cycling a motor load under normal conditions. For heavier AC-4 duty (plugging, inching), the rate drops to 250 ops/h, which tells you this frame is meant for standard starting, not frequent reversing. Auxiliary contacts are built in, so you don't need a separate add-on block for basic feedback or interlocking. The coil is screw-terminated, which is what most panel wiremen expect — no special tooling needed.
Mounting and wiring notes
That gives you options when laying out a dense panel, but keep the clearance in mind — at least 10 mm upward and downward, 6 mm to the side, for arc flash and cooling. Wire preparation is straightforward: strip to the length the terminal requires, use ferrules on stranded if you want a tidy connection. The clamp accepts two conductors of the same size for looping power through multiple contactors.
No need to hunt surplus or worry about a phased-out part.
