Panoramica

FEATURES

Its magnetic holding structure is divided into two types: K type adopts single coil and two-contact self-locking design, which is suitable for simple control occasions; while 2K type adopts double coil and three-contact self-locking design, which provides stronger holding force and stability and is suitable for more complex applications.

In terms of installation, CZW50A-K provides a variety of bracket types, including horizontal installation (default), single vertical, two vertical, two horizontal, etc., so that users can choose according to actual needs.

The contactor also has a variety of functional options, such as with suppression diode (l), with pre-charge resistor ®, increased rated current (U), continuous operation (CO) and intermittent operation (IN) to meet different working conditions and performance requirements.

The coil rated voltage range of CZW50A-K is wide, including 12V, 24V, 36V, 48V, 60V and 72V, ensuring its compatibility and reliability in a variety of voltage environments. This contactor is an indispensable component in industrial automation and electrical control systems.
