The Carlo Gavazzi RA2A60D40M is a compact and reliable two-pole AC solid state relay (SSR) designed for switching and control of demanding inductive AC loads in industrial automation and electrical control systems. As part of the Carlo Gavazzi RA2A solid state relay series, it combines dual control, zero-cross switching and high-current AC switching in a compact panel-mount housing.
This solid state relay uses zero-cross switching to activate each output semiconductor at the first zero crossing of the line voltage. The RA2A60D40M is specifically configured for inductive loads, while its semiconductor output, LED indication and FASTON power connections provide dependable operation and straightforward installation in industrial control equipment.
With a rated operational current of 40 A per pole for AC-51 loads and 15 A per pole for AC-53a loads, together with an operating voltage range of 42–660 V AC, the RA2A60D40M is suitable for demanding AC switching applications. Its two independently controlled poles allow separate AC circuits to be switched from a single compact relay housing.
Solid state relays such as the Carlo Gavazzi RA2A60D40M use semiconductor switching rather than mechanical contacts, providing fast and reliable control of AC loads. The zero-cross switching function activates each output at the first zero crossing of the line voltage, helping provide controlled switching and reduce electrical disturbance.
The RA2A..M configuration is specifically intended for demanding inductive loads and uses Direct Copper Bonding technology within its semiconductor construction. The two independently controlled poles allow separate AC circuits to be switched from one relay housing, while suitable heatsinking helps maintain thermal performance when operating at higher load currents.
