ASCO Power Technologies S50A120V2P Surge Protection Device

ASCO Power Technologies SPDee Series S50A120V2P Surge Protection Device is a compact, line-side surge protector for 120/240 VAC systems that guards electrical distribution panels and attached equipment from transient overvoltages. Configured as a two-pole, split-phase unit with two hot conductors and a neutral, it supports 120/240 VAC operation at 50/60 Hz to match standard North American power infrastructure. The device delivers up to 50 kA of surge current per mode, providing robust protection against lightning and utility switching transients while remaining suitable for both commercial and light-industrial environments. SPDee Series units use large block 50 kA thermal-protected MOVs to clamp overvoltage events and dissipate surge energy, helping minimize the risk of component damage and downtime. This model, designated S50A120V2P, belongs to ASCO’s SPDee family of surge suppressors designed to be installed in panelboards or at power distribution interfaces to safeguard sensitive electronics and control equipment. Its voltage rating of 120/240 VAC and dual-hot-plus-neutral configuration make it compatible with common split-phase service; the 50/60 Hz compatibility ensures operation across standard regional power frequencies. When selecting surge protection for 120/240 V circuits, S50A120V2P offers a straightforward solution that integrates with existing electrical infrastructure without requiring custom adaptations, helping maintain uptime for critical loads while providing a clear protection path for transient events.
