NK AS1-NOR-FT-GO – Current Sensing Relay, Normally Open (Mechanical), Solid-core, Top Terminals, Go/No-Go Version (Fixed-Setpoint)

NK AS1-NOR-FT-GO – Current Sensing Relay, Normally Open (Mechanical), Solid-core, Top Terminals, Go/No-Go Version (Fixed-Setpoint)

• AS1 NOR-FT-GO
• Current sensing switch
• Output rating= normally open (mechanical)
• Case style= solid-core, top terminals
• Options = go/no-go version (fixed-setpoint)

AS1 NOR-FT-Go Series Current Sensing Switches provide an electromechanical relay contact. The output of this specialized switch allows the sensor to control much more current than other AS1 models. This contact can control loads up to 5 A, AC or DC. Solid-state contacts generally have a much lower capacity, making this sensor much more versatile than most self-powered models. Available in a solid-core case only.

Current Sensing Switch Applications

Electronic Proof of Flow

• Current sensing switches eliminate the need for multiple conduits or duct penetrations and are more reliable than electromechanical pressure or flow switches.

Compressor Monitoring

• Detect when the compressor is running.
• Allows for time of use logging; helps maintenance scheduling.

Heaters

• Sense system operation.

Fan Interlocks

• Sense system operation.
• Use to turn on a duct booster fan when clothes dryer is energized.

Current Sensing Switch Features

Electromechanical Output

• N.O. mechanical output relay for detection of current; closes on current increase.

Fixed Setpoint

• Cuts installation and operating costs.

Self-powered

• Reduces installation time and costs.

Integral Mounting Feet

• Built-in feet for direct panel mounting or attachment of DIN rail compatible brackets.*

UL/cUL and CE Approved

• Accepted worldwide.
