Compact surge protector for LED drivers

The Hubbell BSP3-347 is a ballast-rated surge protection device built for 347 V, 50/60 Hz lighting circuits. It fits inside luminaires or remote driver enclosures where transient voltage suppression is required. Installers working on commercial or industrial LED projects use it to shield drivers from line surges.

Rated for continuous 347 V operation

The unit handles sustained 347 V at both 50 Hz and 60 Hz without derating. Its IP65 enclosure resists dust and water jets, so it remains sealed during prolonged exposure in damp or outdoor locations. ROhS compliance confirms restricted substance limits for regulated projects.

Verify voltage, frequency and mounting space

Confirm the supply is 347 V at 50 Hz or 60 Hz before wiring. Check that the driver enclosure has room for the compact module and that the ingress protection rating matches the installation environment. Ensure local codes accept this surge protector for the intended lighting circuit.

Questions about this item

Will the BSP3-347 make noise or get hot running continuously on a 347V 50/60Hz circuit?

The BSP3-347 is a compact surge-protection device with no moving parts, so it produces no audible noise and negligible heat during continuous operation on 347V 50/60Hz circuits.

What wiring or fixtures must I already have to install this BSP3-347 surge protector?

You need a 347V AC supply at 50Hz or 60Hz and an LED driver or ballast circuit to protect; the IP65-rated unit connects in-line with that circuit.

Can the BSP3-347 protect an older magnetic ballast running at 347V 60Hz?

Yes, the device is rated for 347V at 50/60Hz and will suppress surges on any compatible ballast or LED driver circuit, including older magnetic types.
