Compatibility and Installation

Cross-reference: Lewmar DC66-46P. The DC66-53P may be suitable as a replacement where its specifications match the original installation. This cross-reference does not establish suitability for every system using DC66-46P.

Before ordering or installation, compare coil voltage and duty cycle, motor load and switching requirements, terminal arrangement, wiring and polarity, coil suppression, switching timing, mounting dimensions and environmental requirements. Do not assume identical wiring, mounting or drop-in interchangeability. Have suitability and installation checked by a qualified technician.

Coil suppression can affect release timing and compatibility with the control circuit. Check the exact configuration of both contactors rather than relying on part-number similarity.

Applications

• Windlass and thruster motor control, where load and duty requirements are suitable
• Hydraulic pump systems
• Industrial DC motor reversing
