ATC SLA-440-ALE Monitor/Relay, 430-480 Adjustable, Lock Shaft Adjusted, Surface Mounted, 8 Screw Terminals

Model: SLA-440-ALE   |    Mpn: SLA-440-ALE   |    PartNumber: SLA-440-ALE   |   Asin: B00DWI316W

The ATC Diversified SLA Series is designed to protect 3-phase equipment against Phase Loss, Under Voltage, and Phase Reversal conditions. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (Pick-Up). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the drop out voltages, the relay will de-energize (Drop-Out). On models featuring indicators, the LED glows when all line conditions are normal. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are NOT required. For UL Listed units, with field wiring terminals, copper wire with 60 /75 C rating must be used for control circuitry connections. NOTE: When a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage. However, with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted. The SLA Series is UL Listed under File Number E55826.

Features

  • Delta or Wye Systems
  • Fixed, Lock Shaft, or Screwdriver Adjustment
  • Available up to 480 VAC (625 VAC with E Style)
  • Several Enclosure Styles

Supco APR5 Wire to Wire Adjustable Potential Relay, 30 A Load Current, 110 - 270 VAC Single Phase Operating Voltage

 Ean: 0687152010080   |    PartNumber: APR5   |   Asin: B004XS1ML6

This Supco APR5 wire-to-wire adjustable potential relay is used to start 1-phase, capacitor-type motors in air conditioning and refrigeration applications. It is a replacement part with adjustable settings for wire-to-wire replacement of most potential relays with 110 to 270 VAC pickup voltage. It has a safety time-out of 1 to 1.5 sec, at which point the contacts will open if the motor does not start. It has universal, non-positional mounting and adapters for screw or push-on terminals. This adjustable potential relay replaces 3- and 5-terminal potential relays and is suitable for use with single phase motors or air conditioning and refrigeration compressors up to 5 hp.

Specifications Operating voltage 110-270 VAC Load current 30 amp Time setting range 0.05 100 sec Operating temperature -40 to +150 degrees F Dimensions* 1.5 x 2.25 x 1.75" (H x W x D) *H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Relay switches (also called an electrical relay or an electrical relay switch) use a small amount of power to control a larger source of power connected to electrical devices such as car motors, computers, and lighting installations. A basic relay switch has a control circuit with an electromagnetic coil and a load circuit with contacts and a lever. When current flows into the relay switch, it moves through the coil and a magnetic field is created, which causes the lever in the load circuit to move between contacts, either turning the device on or off. In a normally open (NO) relay switch, when power is supplied to the relay, the load circuit is closed and the power source connected to the relay is turned on. In a normally closed (NC) relay switch, when power is supplied to the relay, the load circuit is open and the power source connected to the relay is turned off. In other types of relay switches, non-moving parts such as transistors or semiconductors can be used as the control circuit to operate the switching mechanism. Relay switches can be controlled with an external switch, such as a light switch, or they can be connected to an automatically switched power source, such as a car ignition. One relay can operate multiple switches, and multiple relays can be operated with a single switch, with each relay operating independently from the other relays in the system.

Supco manufactures test instruments and replacement parts for heating, ventilation, air conditioning, and refrigeration systems. The company, founded in 1945, is headquartered in Allenwood, NJ.
