The 52297587 is a genuine on-delay contact block tailored for lifting equipment (cranes, hoists), serving as a key auxiliary electrical component in control circuits to realize time-delayed switching of signals.
It works with the main contactor or control relay of lifting equipment to provide time-delayed closing/opening of auxiliary circuits. Typical applications include delaying the start of auxiliary mechanisms (e.g., cooling fans, lubrication pumps) after the main motor starts, or delaying the activation of protective devices (e.g., overload alarms) to avoid false triggers from instant current surges. It ensures sequential and stable operation of the equipment’s electrical system.
As a genuine part, it perfectly fits original control components (e.g., contactors of the same series), ensuring no mismatch in installation and circuit connection.
Adopts precision timing mechanisms with stable delay accuracy, unaffected by industrial site voltage fluctuations or temperature changes.
Sealed structural design resists dust, vibration, and humidity in workshops/warehouses, matching the harsh operating conditions of lifting equipment.
Standardized snap-on design allows quick disassembly and replacement without complex tools, reducing equipment downtime during maintenance.
It is mainly used for maintenance and replacement of CXT series hoists, small-to-medium gantry cranes, and overhead cranes. When the original time-delay contact block fails (e.g., inaccurate delay, contact failure), replacing it with 52297587 restores the normal sequential control of the equipment’s electrical system. For exact parameters (e.g., specific delay range, contact quantity), confirm using the part number 52297587.
