Allen-Bradley 1336-SN-SP16A Inverter Snubber Module

The Allen-Bradley 1336-SN-SP16A Inverter Snubber Module is a single‑sided PCB designed to absorb voltage spikes generated during inverter switching, protecting the drive’s IGBT and power semiconductors in Frame F 1336-series systems. It is installed inside Allen-Bradley 1336 PLUS, 1336 PLUS II, 1336 FORCE, and 1336 IMPACT drives to suppress transients for reliable high‑power motor control. Specified for 460 VAC to 575 VAC input and a maximum drive rating up to 800 HP, this internal‑mount snubber PCB fits Frame F drives and weighs approximately 1 lb (0.45 kg). Common applications include industrial automation setups using 1336 series drives in conveyors, pumps, compressors, fans, and manufacturing equipment. For reference, common replacements include the 1336-SN-SP14A, 1336-SN-SP17A, and 1336-SNMX3-SP8A snubber PCBs.
