120 HWCP 20 or 120 HWCP 20 CB: 120 Volt AC 3-Wire Single Phase (20 Amp) CB indicates built-in circuit breaker. This
is a hardwired in-line series (AC) surge suppressor and is designed to
protect branch circuits, fire alarm or dedicated PLC equipment with a
maximum current draw of 20 amps. It provides both common and normal three-phase noise filtration. UL 1449 listed and rated 400V peak for L-N, L-G, N-G. This unit is available with (120HWCP20CB) or without (120HWCP20) a circuit breaker.
ILDCP Series Models: These are UL listed 497B in-line series screw terminal multi-stage hybrid devices. These
units are designed not only to protect equipment but also reduce the
incidence of false alarms due to its close clamping ability at
high-induced voltages. There is a ground lug provided. Only use if you have a common ground i.e. single ground for entire system to prevent ground loops.
FA-30: 30 Volts DC to be used on the initiating circuits and addressable loops operating at 24V DC that are drawing less than 1 amp.
FA-60: 60
Volts DC to be used on the initiating circuits and addressable loops
operating above 24V DC (38V DC) that are drawing less than 1 amp.
DLT TOS 200: 200 Volts DC to be used on equipment connected to your telecommunication lines with ring voltage. i.e.(RJ31X)
* For notification appliance circuits that draw up to 3 amps add NC after the part number.
