Current surge protection is provided through sneak current fuses or resettable PTCs. The UP3B-75 fits all 66 Type M Blocks. Features dual indicator lights-protection OK and ground OK. Provides the fastest response to transient voltages (2-5 nanoseconds) by quickly diverting damaging surges to ground and resetting. Scale the protection to the system size. Protect only the lines requiring protection. Eliminate expensive five-pin blocks while using economical 66 Blocks. Eliminate redundant
The UP3B-75 is ideal for retrofit applications-just remove the bridging clips from the block and replace them with the UltraLinx protector. Add the ground connection and the pair is protected!
