The DS250E is an extreme duty Type 1+2 designed to protect the entrance of the electrical installation. The DS250E is a one-pole SPD and can be used in common mode or common and differential mode. DS250E AC surge protectors are designed to be connected in multi-pole configuration to protect single-phase, 3-phase and 3-phase+neutral AC networks. This SPD is DIN rail compatible,
