Omron G3NA-220B-UTU 100-240VAC Single Phase SSR: Technical Guide, Applications and Installation

The Omron G3NA-220B-UTU 100-240VAC is a Single Phase SSR developed for engineers who understand that the cost of an unplanned stop far exceeds the cost of a quality component. Rated at 100-240V AC, it addresses real challenges found in AC control circuits without overcomplicating installation or maintenance.

Omron’s strength lies in offering complete automation subsystems rather than isolated components. The Omron Sensor lineup complements the relay and switch range by providing the detection layer, so the entire signal chain — from physical event to control output — stays within one trusted supplier.

Understanding the Omron G3NA-220B-UTU 100-240VAC Single Phase SSR

The Omron G3NA-220B-UTU 100-240VAC is a Single Phase SSR rated at 100-240V AC, built to handle AC control circuits reliably over a long service life. Key engineering features include ac control input, zero-cross switching, optical isolation, and the unit mounts via heatsink or panel.

Technically, the Omron G3NA-220B-UTU 100-240VAC delivers ac control input, zero-cross switching, optical isolation. Matching the 100-240V AC control bus requires no extra hardware, which keeps commissioning time short and the panel design clean.

Application Scenarios

The Omron G3NA-220B-UTU 100-240VAC Single Phase SSR is commonly specified for the following applications:

  • Ac control circuits
  • Single-phase heater and motor control

Across these use cases, the consistent thread is a need for dependable switching over a large number of operations, often in environments where an unplanned fault would create significant disruption. The Omron G3NA-220B-UTU 100-240VAC is designed with exactly those conditions in mind.

Getting It Right at Installation

Commissioning the Omron G3NA-220B-UTU 100-240VAC Single Phase SSR is straightforward. Snap or screw it into position on the DIN rail, connect cables at the correct terminals, and confirm polarity where applicable. During the first powered test, verify that the indicator LED (where fitted) responds correctly and that the output contacts behave as expected under a controlled test load.

For ongoing maintenance, periodically inspect for contact discolouration, check terminal screws for loosening, and look for any signs of heat stress on the housing. Catching these early avoids the much larger cost of an unplanned production stop.

Why Engineers Choose Omron

Specifying the Omron G3NA-220B-UTU 100-240VAC Single Phase SSR also means specifying into an ecosystem. Omron’s portfolio covers relays, sensors, PLCs, power supplies, and more — all engineered to work together. When a component does eventually need replacing, compatibility with the rest of the system is guaranteed, which is something off-brand alternatives simply cannot offer.

Frequently Asked Questions

What applications is the Omron G3NA-220B-UTU 100-240VAC designed for?

The Omron G3NA-220B-UTU 100-240VAC Single Phase SSR is designed primarily for AC control circuits, single-phase heater and motor control. Its construction and contact ratings make it well suited to both continuous-duty and intermittent switching in these environments.

What coil voltage does the Omron G3NA-220B-UTU 100-240VAC use?
