XBDM HW Bypass Distribution Module
15A, 20A, 30A, 63A
XBDM HW provides UPS maintenance bypass with input and output hardwired terminal block connections.
XBDM HW Bypass Distribution Module
The XBDM HW provides UPS maintenance bypass with hardwired terminal-block input and output. Transfer critical loads from UPS power to utility power with a single bypass switch — so the UPS can be repaired or replaced without ever dropping the load.

Continuous uptime for your critical electronics
The XBDM HW lets you manually transfer critical loads from UPS power to utility power using a bypass switch, enabling UPS repair or replacement without power interruption to the load. Transferring back to protected UPS power is just as easy — simply return the bypass switch to the UPS position.
Available in 15A, 20A, and 30A 120VAC ratings plus a 230VAC/63A model, the XBDM HW uses hardwired terminal-block connections for both utility input and system output. The 15A and 20A models add six 5–15R output receptacles and source-availability LED indicators, and keep connected loads surge protected even when the UPS is in bypass mode.
Built for clean, code-compliant installs
Hardwired input and output terminal blocks for direct connection to utility and load.
The 15A and 20A models also provide six 5–15R output receptacles for connected equipment.
LED indicators on the 15A and 20A models verify availability of UPS and utility sources at a glance.
Loads stay surge protected on the 15A and 20A models even in bypass mode; UPS electronics are protected during normal operation.
The 63A model provides make-before-break transfer and an interlock for the UPS static switch.
Wall and 19″ rack mounting hardware is included in the box.
Two modes of operation
A single bypass switch moves your critical loads between protected UPS power and direct utility power. Output to the connected loads always comes from the XBDM HW — so you can service or swap the UPS without ever dropping the load.
1) Utility mode
Utility power bypasses the UPS system and is supplied to the load directly — used while the UPS is serviced or replaced.
2) UPS mode
Power is routed through the UPS system to the connected load — the normal, fully protected operating state.

XBDM HW — frequently asked questions
What is the difference between the XBDM HW and the XBDM?
Connections. The XBDM HW uses hardwired terminal blocks for utility input and system output, which suits code-driven and permanent installations. The plug-and-receptacle XBDM uses cord connections and provides up to ten output receptacles. The bypass function is the same on both.
Which XBDM HW model matches my UPS?
By current and voltage. The XBDM-15RHW and XBDM-20RHW cover 120 VAC at 15 A and 20 A and add six 5-15R receptacles, LED indicators and surge protection. The XBDM-HW30 covers 120 VAC at 30 A with a 30A/1P input breaker. The XBDM-HW63 covers 230 VAC at 63 A with a 63A/2P breaker.
What is make-before-break transfer, and which model has it?
The XBDM-HW63 only. Make-before-break means the incoming source is connected before the outgoing one is released, so transfer time is 0 ms rather than the 8 ms of the break-before-make models. It also carries a static-switch interlock and is intended for use with a UPS that supports one; the P91 5-10 kVA is the current platform in that capacity range, and interlock support should be confirmed for the specific model before ordering.
Is the load surge protected during bypass?
On the 15 A and 20 A models, yes: 6500 A maximum spike current, 114 J energy dissipation and 330 VAC maximum clamping voltage, active in both modes. The HW30 and HW63 do not include surge protection.
What comes in the box?
Standard 19-inch rack mounting hardware and the user manual. Input cord sets and connectors are available as options.
What warranty applies?
Three years in the USA and Canada.
