AGLD series ground fault sensors keep machinery and their operators safe from accidental shocks.

The large, one piece solid-core design allows for installation over wires feeding heavy loads. The output relay will change state at any point between 5 and 100 mA, or 80 and 950 mA. A delay can be set to allow down stream protection to activate before this sensor, keeping the main circuit protection hot and the equipment energized while the smaller faults are cleared.

AGLD Series

Instruction Manual

The large LED display shows the precise trip point and the extra delay clearly, in any light condition. The display flashes when there is current sensed over the trip point. AGLD series relays monitor all current carrying wires in single or three phase systems to detect ground faults. They provide a contact output that can operate relays, contactors or signal automation systems.

All low-current ground-fault relays are sensitive devices that require reasonable care in system design to avoid false trips caused by high electrical noise levels. Keep in mind that the best way to reduce noise in a system is to suppress it at its source.


  • Monitor Large Machines
    • Detect fault currents before damage can occur. Connect the output to a shunt trip breaker operating solenoid or to the circuit powering a connector coil.
  • Water Delivery and Treatment
    • Detect moisture ingress in submersible pumps.
  • Heating Processes
    • If an element shorts to ground, the sensor will activate to de-energize the circuit, keeping safety at the forefront.


  • Electromechanical Relay Output
    • Provides both normally open and normally closed contacts.
    • Compatible with most automation and control systems.
  • Externally Powered
    • A choice of fail safe or standard operation.
  • Simple Field Setpoint Adjustment
    • Single turn potentiometer with setpoint shown on display.
    • Adjustable delay shown when knob is turned.
  • Large Solid-Core Case
    • Large sensing window provides ample space for multiple conductors.
  • DIN Rail Mount
    • Simple snap onto DIN rail
  • Designed for UL, CUL and CE Approval
    • Accepted around the world.

IDEC Switches

LW Silhouette Series switches make a personal statement about style with sharp lines and stunning colors. Projecting only 2mm when mounted on a panel, these switches provide a sleek, updated look while maintaining the highest levels of reliability. LW Silhouette switches are perfect for industries requiring a hygienic surface. A smooth design cuts down on surface area preventing dust and other particles from accumulating on the machine.

SSAC Controls

SSAC LLC8 Series is a low cost, single-probe conductive liquid level control designed for low liquid level cutoff protection. It offers a factory fixed time delay of 1 - 60s and is available for input voltages of 24, 120, or 230VAC. LED indicator illuminates whenever the LLC8's isolated, 10A, SPDT output relay is energized. Sense resistance is fixed from 5K - 250KΩ. Available with manual/automatic reset or a special manual reset
