GE IAC66K57A Time-overcurrent relay

The GE IAC66K57A has the following specifications:

• Voltage: 240 VAC
• Current: 100-200 amps
• Trip time: 0.1-10 seconds
• Trip current: 150-250 amps
• Magnetic trip current: 400 amps

The relay is housed in a black plastic enclosure with a red handle. The front of the enclosure has a terminal block for the incoming and outgoing circuit conductors. The back of the enclosure has a terminal block for the trip coil.

The GE IAC66K57A is used in a variety of applications, including:

• Motor protection
• Lighting protection
• Appliance protection

The relay is typically installed in a panelboard or junction box. It is connected to the circuit conductors by means of lugs or wire nuts. The trip coil is connected to a 240-volt AC source.

The GE IAC66K57A is a reliable and easy-to-use TOR that is ideal for a variety of applications.

Here are some additional details about the relay:

• The thermal trip element is made of a bimetallic strip that bends when the current exceeds a preset value. The bending of the strip opens the circuit.
• The magnetic trip element is made of an electromagnet that pulls in a plunger when the current exceeds a preset value. The plunger opens the circuit.
• The relay has a reset button that can be used to reset the relay after it has tripped.

The GE IAC66K57A is a valuable tool for protecting electrical circuits from overloads and short circuits.
