Good To Know
Q: Can this contactor be used with a 36V system? A: No, this unit is specifically rated for 48V coil operation; applying 36V may not fully engage the contactor, and higher voltages could damage the coil.
Q: Is this an original Curtis part? A: This is an aftermarket replacement built for Curtis and ZAPI controller systems, not an OEM part, but it matches the SW80B-156 specification for interchangeability.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
