^{AS1 Series Current Sensing Switches combine a current transformer, signal conditioner and limit alarm into a single package for use in status monitoring or proof of operation applications. Offering an extended setpoint range of 1–150 A and universal, solid-state outputs, the self-powered AS1 can be tailored to provide accurate and dependable digital indication of overcurrent conditions across a broad range of applications. Available in solid-core case styles or in a split-core case to maximize ease of installation.} 

Current Sensing Switch Ap​plications

Electronic Proof of Flow

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

Conveyors^​

  • Detects jams and overloads.

  • Interlocks multiple conveyor sections.

Lighting Circui^​t_​s_​

  • Proof positi​ve that the lamp is energized.

Electrical Heate^​rs

  • Faster response than temperature sensors.
