Carlo Gavazzi RZ3A60A55 3-Pole Panel Mount SSR Zero-Cross Switching

The Carlo Gavazzi RZ3A60A55 is a three-pole, panel-mount solid state relay (SSR) featuring zero-crossing switching technology. Designed for demanding HVAC, building automation, and industrial control applications, this SSR delivers silent, arc-free switching with no moving parts — eliminating the wear and maintenance concerns associated with electromechanical contactors.

Zero-Cross Switching Technology

The RZ3A60A55 switches AC loads at the zero-crossing point of the voltage waveform, dramatically reducing electrical noise and electromagnetic interference (EMI). This makes it an ideal choice for sensitive control environments where signal integrity and equipment longevity are priorities.

Three-Pole Configuration

With three independent output poles in a single compact housing, this SSR is well suited for controlling three-phase loads such as electric heating elements, motors, and other balanced three-phase HVAC equipment — all from a single panel-mount device.

Key Features

• Three-pole solid state relay in a single panel-mount package
• Zero-cross switching for reduced EMI and extended load life
• No mechanical contacts — silent, spark-free operation
• Compact panel-mount form factor for easy enclosure installation
• Suitable for three-phase resistive and inductive load control
• Designed for HVAC, building automation, and industrial control systems
• Carlo Gavazzi quality construction for long-term reliability

Applications

• Three-phase electric heating element control
• HVAC equipment switching and load management
• Building automation and energy management systems
• Industrial process control panels
• Motor and resistive load switching

Why Choose a Solid State Relay?

Unlike traditional electromechanical relays and contactors, solid state relays offer virtually unlimited switching cycles, silent operation, and immunity to vibration and shock. The absence of mechanical contacts means no arcing, no contact bounce, and no audible clicking — resulting in a longer service life and reduced maintenance costs over the life of the installation.
