1 Single Phase

Load Types:

Inductive - Instantaneous Control (or Random Relay) designed for motors AC-53 and inductive loads

General - Zero Voltage Control (or Zero Crossing Relay) designed for most types of loads mainly resistive AC-51 but with a bit of inductance

Resistive - Zero Voltage Control (or Zero Crossing Relay) designed for resistive loads AC-51 e.g. Heating Elements
