Fotek SSR-75VA 75A AC Solid State Relay Module, 24–380V AC

Description

Fotek SSR-75VA 75A AC Solid State Relay Module

The **Fotek SSR-75VA solid state relay** is a single-phase electronic switching module designed to control compatible AC loads without the moving contacts used in conventional electromechanical relays. It is intended for applications where electronic switching can support frequent operation and reduced mechanical contact wear.

The uploaded product image identifies the model as **SSR-75VA**. Although the supplied product name says KSR-75VA, the label and Fotek’s official product listing support SSR-75VA as the correct model designation.

Key Product Specifications

– **Brand:** Fotek
– **Model:** SSR-75VA
– **Product type:** Single-phase solid state relay module
– **Maximum rated load current:** 75 A
– **Maximum rated load-voltage range:** 24–380V AC
– **Control method:** Variable-resistor control
– **Control resistor specification shown on label:** 500 kΩ, ¼ W
– **Mounting:** Panel mounting through the module’s mounting points

The 75 A figure is a maximum rated current, not a guarantee that the relay can continuously carry 75 A under every ambient temperature or installation condition. The exact control wiring and operating limits should be checked against the manufacturer’s documentation.

Main Features and Benefits

Electronic AC Switching
Solid state switching uses semiconductor components rather than mechanical contacts. This can be useful in applications that require frequent switching.

High-Current Load Control
The SSR-75VA is rated for loads up to 75 A under the manufacturer’s specified conditions. Actual capacity depends on load characteristics, ambient temperature, installation, and heat dissipation.

Variable-Resistor Control
The product label identifies a variable-resistor control arrangement and specifies a 500 kΩ, ¼ W resistor. Follow the correct wiring diagram and control method for this particular model.

Compact Panel-Mount Construction
The module’s mounting holes support installation in a suitable electrical panel or equipment assembly.

Typical Applications

Depending on the load and control design, the SSR-75VA may be considered for:

– Industrial heating control
– Temperature-control systems
– Compatible resistive AC loads
– Industrial process equipment
– Automated AC load switching

Confirm suitability for the specific load before installation. Motor, transformer, lamp, and other inductive or high-inrush loads may require additional consideration.

Installation and Safety Guidance

Solid state relays generate heat during operation. A suitable heat sink and appropriate thermal management may be essential, particularly at higher load currents. Follow Fotek’s installation guidance and derate the relay as required for ambient temperature and cooling conditions.

Also verify the wiring diagram, control input requirements, load current, AC voltage, enclosure, and overcurrent protection. Solid state relays may have off-state leakage current and can fail in a conducting state, so they should not be treated as an isolation device or the sole means of electrical disconnection.
