The Anly ASR100AAH is a 100A Solid State Relay built for AC to AC switching in industrial control panels. It takes an 80 to 280VAC control signal and switches loads across a 48 to 480VAC range, so a low current signal from a controller, timer or thermostat can drive a heavy resistive or inductive load without any mechanical contact in the path.

Because a Solid State Relay switches through semiconductors rather than moving contacts, it has no arcing, no contact wear and no audible click. That gives it a far longer service life than an electromechanical contactor on high cycle duty, which is why an SSR is the standard choice for heater control, oven zones and any application where the load is switched thousands of times a day.

The unit measures 57mm by 43mm by 25.3mm and mounts flat to a panel or heatsink plate. At 100A continuous, a properly sized heatsink is essential, since the internal semiconductors dissipate heat in proportion to load current. It carries UL, C-UL and CE approvals, so it suits export panels and inspected installations.

Common Applications

Electric heater and heating element control, plastic injection and extrusion barrel zones, industrial ovens and furnaces, packaging and sealing machines, temperature controlled process lines, lighting control, and any panel where an AC control signal has to switch a high current AC load repeatedly. In most of these builds the SSR is driven by a temperature controller or a digital timer mounted on the same panel door.

Choosing the Right Model

If your controller gives a DC output rather than an AC signal, use the 100A Solid State Relay DC to AC version instead, which accepts 4 to 32VDC from a PLC card. For lighter loads the same Anly series covers a 40A Solid State Relay and a 25A Solid State Relay, and DC loads are handled by the 25A DC to DC SSR. Our complete Solid State Relay range lists every current rating we hold in stock.

FAQ

What does a 100A Solid State Relay do?

It switches an AC load of up to 100 amps using an electronic control signal instead of a mechanical contact. Applying the control voltage turns the output on, removing it turns the output off, with no moving parts involved.

What is the difference between AC to AC and DC to AC SSR?

It refers to the control input. This model accepts an 80 to 280VAC control signal, while a DC to AC model takes 4 to 32VDC from a PLC or controller output. The load side is AC in both cases.

Does a 100A SSR need a heatsink?

Yes. At high load currents the relay generates significant heat and must be mounted on an adequately sized heatsink with thermal paste. Running 100A without proper heat dissipation will shorten its life considerably.

Can it switch a motor?

It can switch inductive loads, but starting current and power factor must be accounted for when sizing. For most motor duty a correctly rated contactor or purpose built motor starter is the safer choice.

Is it suitable for 415V three phase?

The load range extends to 480VAC, so it works at 415V. This is a single phase device, so three units are needed to switch all three phases.
