Briggs & Stratton 50 A NEMA 4 Low Voltage Module for Symphony II Transfer Switch

The Briggs & Stratton Symphony II Low‑Voltage Module brings intelligent, priority‑based load control to thermostatically operated appliances. Rated at 50 A and enclosed in a rugged NEMA 4 plastic housing, it lets your Symphony II transfer switch manage a central A/C — or any 120‑volt comfort load — without stressing the generator.

• 50 A low‑voltage load‑management module
• Handles one 120 V thermostatically controlled circuit (central A/C, furnace blower, etc.)
• NEMA 4 rain‑, dust‑, and ice‑resistant enclosure (indoor/outdoor rated)
• Designed exclusively for Briggs & Stratton Symphony II transfer switches and compatible standby generators
• Priority logic sheds and restores loads to prevent generator overloads
• Plug‑and‑play 18 AWG control wiring; mounts right at the appliance
• Link up to eight modules per system for whole‑house management
• UL listed • 3‑year limited warranty

Smart comfort control

During an outage, Symphony II constantly reads generator output and energizes the connected A/C only when capacity is available. Your home stays cool without tripping breakers or stalling the engine.

Simple, tool‑free programming

Set a few DIP switches to Essential, Managed, or Deferred; the transfer switch instantly recognizes the module and follows your priority plan — no laptops or field firmware needed.

Built for harsh spots

The gasketed NEMA 4 enclosure shrugs off rain, dust, hose‑down water, and sleet. Install it in the attic, near the condenser, or on an exterior wall with total confidence.

Fast, clean installation

A compact 8.75'' x 5.5'' x 3'' footprint and pre‑drilled flanges let techs mount the box in minutes. Low‑voltage wiring means no conduit wrestling or heavy conductors.
