It's built for standard motor starting duty (AC-3 utilisation category), meaning it's designed to switch three-phase induction motors on and off under full load — the kind of work you'd see on a conveyor, pump, or fan in a panel that needs local push-button control.
Motor power coverage and control voltage
The starter covers a practical range of motor sizes: 15 kW at 380/400 V and 415 V, 18.5 kW at 500 V and 660/690 V, and 7.5 kW at 220/230 V — all at 50/60 Hz. That's enough for a mid-size pump or a small compressor. The control circuit is 24 V AC, which keeps the push-button voltage safe for operators and lets you tie into a standard control transformer without a separate DC supply.
What the standards tell you
The starter complies with IEC 60947-4-1, the standard for contactors and motor-starters. That's the benchmark for AC-3 switching duty, thermal performance, and coordination with upstream protection. The associated fuse rating is 32 A, 14 x 51 mm aM — so if you're building a new panel or replacing a failed unit, make sure the fuse holder matches that cartridge size.
Dimensions are 186 mm wide, 330 mm tall, and 175.5 mm deep. The polycarbonate enclosure has cable entries pre-punched for ISO20, ISO25, ISO32, and ISO40 glands — two at the top and two at the bottom. That gives you flexibility for incoming supply and outgoing motor cables without drilling. The enclosure is standalone; it doesn't snap onto DIN rail, so plan for direct panel or wall mounting with clearance for the door swing if the push-buttons need access.
