Multiquip A200160100 GBX III Control Panel Relay B - OEM Replacement Part

This control panel relay manages critical electrical switching functions within the GBX III series light tower control system, enabling proper lamp operation and power distribution between the upper and lower lighting circuits. Relay B works in conjunction with the control panel switches to activate lighting units when lamp switches are pressed, and coordinates with the breaker system to protect electrical circuits from overload conditions.

Located inside the control box alongside other electrical components including fuses, connectors, and the ECU, this relay is essential for troubleshooting common lighting failures. When all lighting units fail to illuminate despite the ignition key being turned and switches being activated, relay failure is a potential cause alongside tripped breakers or miswiring issues. The relay interfaces with the 120V AC system that powers both upper and lower lamp arrays, making it a critical component for maintaining full operational lighting capacity on jobsites.

During routine electrical component maintenance, technicians should verify that all connectors on the control box are properly seated and functioning. This relay is accessed by opening the control panel door where switches, meters, and the capacitor terminal block are located.
