Description
The Hyundai HMX 40 is a heavy-duty auxiliary contactor relay manufactured by Hyundai Heavy Industries Co., Ltd. (Made in Korea). Unlike standard contactors designed for direct motor loads, the HMX series is optimized for intermediate control logic, interlocking, and pilot-duty switching. The 40 configuration provides 4 Normally Open (NO) main auxiliary contacts across all four poles.
Built to meet rigorous marine and offshore environment demands, these units feature marine type-approvals from LR, BV, NK, KR, and ABS, ensuring reliable performance against engine room vibration, ambient humidity, and temperature variations.
