Siemens 87hug6mc Pump Control Panel 50 Hp Nema 3/3R

Product Description

The SIEMENS 87hug6mc is a Class 87 surface mount pump control panel designed for three-phase motor control in commercial and industrial applications. Rated for up to 50 horsepower and 90 amps at 600 volts AC, the panel accepts coil voltages ranging from 220 to 480 volts AC and operates at 50/60 Hz. It houses a solid-state overload relay and a HAND/OFF/AUTO selector switch, giving operators direct on-site control with the added flexibility of automatic or remote reset. Licensed electricians and pump system technicians are the primary installers for this panel.

This pump control panel is built for motor control and weather-resistant outdoor installations. Its NEMA 3/3R rated enclosure makes it suitable for surface mounting in exposed outdoor environments where protection against windblown dust and rain is required. The three-pole configuration supports standard three-phase pump motor circuits. The panel measures 41 inches high by 24 inches wide by 8 inches deep, making it appropriate for dedicated wall or structure-mount installations in pump stations, irrigation systems, and similar mechanical applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out all power to the circuit before opening the enclosure or making any wiring connections. Use appropriately rated conductors and verify that supply voltage matches the panel coil voltage range before energizing. Do not install in enclosures or locations that exceed the rated operating temperature range of -4 to 104 degrees F.
