Introduction

Industrial single-phase relays with anti-parallel thyristor output are the most widely used industrial SSRs due to their versatile application possibilities. These relays are suitable for resistive, inductive, and capacitive loads. Zero-switching relays turn on at the zero crossing of the sine wave and turn off at the zero crossing of the current. Instant-on relays with DC control input can be used for phase angle control. Built-in snubbers ensure transient protection. An LED indicates the status of the control input. A snap-on cover ensures touch protection (IP 20). Protected output terminals accommodate cables up to 16 mm in diameter.
