The 2910356 is a Type 1/2 surge protective device for two-channel, 120V AC power systems. It operates with a maximum continuous voltage (MCOV) of 175V AC (L-N) and 264V AC (N-G). This SPD provides a UL-rated nominal discharge current (In) of 20 kA and can handle a maximum surge current of 65 kA per phase. Key features include a high short-circuit current rating (SCCR) of 200 kA, a pluggable two-section design for 35 mm DIN rail mounting, and both optical and remote contact signaling for fault indication. Its robust design and high ratings make it suitable for protecting sensitive equipment in TN-S and TT power distribution systems.
