Hardwire surge protection devices protect against power surges, voltage fluctuations and incorrectly wired shore supply that can cause damages to power distribution systems. These SPDs detect and limit transient voltages and power surges for protecting equipment connected to power and signal lines. Raptor Supplies offers an array of hardwired surge protective devices from brands like Mersen, Sola/Heavy-Duty, Erico, Bussmann and Square D. Some models feature an LED status indicator to provide visual indication for immediate response when the suppressor is damaged. These devices come in IP20 & IP65 enclosures to offer dust-tight operation for indoor & outdoor applications, respectively. These surge protection devices are available in filtering and non-filtering models on Raptor Supplies.
