LETOP manual contactors offer dual-mode switching: automatic electromagnetic and direct manual control. Features include clear position indicators and current ratings from 16A to 100A, with 2-4 pole configurations supporting AC/DC voltages. The dual-mode operation is mechanically locked so there won’t be any control conflicts. Enhanced contact systems ensure long-term electrical reliability by avoiding manual switching and ensuring frequent contact.
LETOP Manual Modular Contactors are designed for applications where direct manual control is required. These contactors are easy to use and reliable, so you can easily control electrical circuits without the need for automated systems. With a focus on ease of operation and mechanical durability, LETOP contactors are perfect for installations that demand straightforward control solutions.
