This Surgelogic SSP02SBA16D is a Type 1 surge protection device rated for 160 kA per phase on a 208Y/120 V AC 3-phase 4-wire system. MCOV sits at 150 V — right at the line-to-neutral ceiling for that voltage class, so keep the supply steady; sustained overvoltage will push past the MOV blocks. SCCR of 200 kA means it can ride out the fault current at the service entrance if it's coordinated with the upstream OCPD.
Rating context
Surge current per phase is 160 kA; SCCR is 200 kA. The NEMA 1 enclosure measures 4.40 x 17.90 x 6.90 in.
