Crestron part number ZUMNET-JBOX-16A-LV
The Crestron ZUMNET-JBOX-16A-LV is a Zum wired load controller that mounts on a junction box and dims 0-10V LED drivers or 4-wire fluorescent ballasts. It switches loads up to 16A at 100-277V with zero cross switching, and uses Zum Net and Zum Link communication within a Zum wired commercial room lighting system.

About the Crestron ZUMNET-JBOX-16A-LV
Zero cross switching is provided for high inrush lighting loads, with a load rating of 16A at 100-277V AC, 50/60 Hz, or 0.5 HP at 120-277V AC. Switched load types include LED, electronic ballasts, incandescent, magnetic and electronic low-voltage, neon/cold cathode, high-intensity discharge and small motor. The 0-10VDC dimming output handles 60mA maximum sink or source.
Two ZUMNET (LAN) RJ-45 ports connect to the control system or a Zum Net device and daisy-chain onwards, and two ZUMLINK (ROOM) RJ-45 ports daisy-chain in-room Zum Link devices, with 85mA available to power them, including ZUMLINK-KP keypads. Spring clamp inputs take an occupancy sensor, a photo sensor and an override control. It connects over Ethernet to a ZUM-HUB4 control system, sold separately.
The white plastic housing is UL 94 5VA flame rated and mounts to the side of a standard 4 in. square junction box through a 1/2 in. conduit knockout. Wiring is by flying leads: black line, white neutral and red AC power output at 14 AWG, and purple and pink 0-10V dimming leads at 18 AWG. It measures 123 mm high, 108 mm wide and 52 mm deep and is rated for 0 to 40 °C.

Questions about the Crestron ZUMNET-JBOX-16A-LV
What is the Crestron ZUMNET-JBOX-16A-LV?
It is a Zum wired load controller that mounts to a junction box. It provides 0-10V dimming for LED drivers or 4-wire fluorescent ballasts and zero cross switching of loads up to 16A at 100-277V AC, with Zum Net communication for network expansion and Zum Link for in-room control.
What loads can the ZUMNET-JBOX-16A-LV switch?
The load rating is 16A at 100-277V AC, 50/60 Hz, and 0.5 HP at 120-277V AC. Crestron lists LED, electronic ballasts, incandescent, magnetic low-voltage, electronic low-voltage, neon/cold cathode, high-intensity discharge and small motor loads, and zero cross switching is provided for high inrush lighting loads.
How does the ZUMNET-JBOX-16A-LV mount?
It mounts to the side of a standard 4 in. square junction box through a 1/2 in. conduit knockout, and Crestron states it meets the requirements of UL 2043. The white plastic housing is UL 94 5VA flame rated and measures 123 mm high, 108 mm wide and 52 mm deep.
What connects to it?
Two ZUMNET (LAN) RJ-45 ports take the control system or Zum Net connection and daisy-chain further Zum Net devices. Two ZUMLINK (ROOM) RJ-45 ports daisy-chain in-room Zum Link devices and supply 85mA for them, including ZUMLINK-KP keypads. It integrates with Zum keypads and occupancy, vacancy and daylight sensors, and connects over Ethernet to a ZUM-HUB4 control system, all sold separately.
What do the TEST button and LEDs do?
Pressing TEST toggles the switched load output on and off, and pressing and holding it cycles the dimming level. Bi-colour ZUMLINK and ZUMNET status LEDs light green in normal operation and red when a fault is detected. There are also LEDs marked 24V, O, D and OVR.
How much is the Crestron ZUMNET-JBOX-16A-LV?
Crestron asks its dealers to give the price of the ZUMNET-JBOX-16A-LV directly rather than publish it online. Add it to your quote list and we will send you a written quote, with delivery, and installation and programming if you need them.

Is the ZUMNET-JBOX-16A-LV in stock?
We order Crestron for each quote, so availability depends on Crestron's stock at the time. We check it before we quote and put the expected delivery date on your quote, so you know where you stand before you pay.
Can I buy the ZUMNET-JBOX-16A-LV without installation?
Yes. We supply Crestron to end users, with or without installation. Like most Crestron devices of this type, it needs setting up or programming before it works in a system, and we can quote for that too.
