Why Choose the Carlo Gavazzi RA40110H10NCS Solid State Relay?
The Carlo Gavazzi RA40110H10NCS is a high-current single-phase AC solid state relay (SSR) designed for reliable switching and monitoring of demanding industrial AC loads. As part of the Carlo Gavazzi RA series, this SENSE version combines zero-cross switching with integrated system monitoring and a normally closed NPN alarm output for enhanced control and diagnostic capability.
The RA40110H10NCS provides semiconductor-based AC switching without mechanical contacts, helping deliver fast and dependable operation in industrial automation and electrical control systems. Its integrated sensing and monitoring functionality can provide additional indication of relay or load conditions, while the panel-mount construction allows straightforward installation with suitable heatsinking.
With a rated operational current of 110 A AC for AC-51 loads and 30 A AC for AC-53a loads, together with a 150–440 V AC operating voltage, the RA40110H10NCS is suited to high-current industrial switching applications. The relay uses a 20–32 V DC external supply and provides an NPN normally closed alarm output for system monitoring.

Reliable High-Current Switching with System Monitoring
Solid state relays such as the Carlo Gavazzi RA40110H10NCS use semiconductor switching rather than mechanical contacts, providing reliable high-current control of AC loads. The zero-voltage switching function activates the output around the zero crossing of the AC waveform, helping provide controlled switching and reduce electrical disturbance.
The SENSE functionality adds system monitoring to the switching circuit, making the RA40110H10NCS suitable for applications where the condition of the relay and connected load needs to be supervised. Its normally closed NPN alarm output can be incorporated into a control system for diagnostic and fault signalling.
Typical Applications
- Industrial automation control panels.
- High-current AC load switching.
- Industrial heating and temperature control systems.
- Production and processing machinery.
- Motor and machinery control applications.
- OEM equipment requiring load monitoring.
- Electrical control cabinets and industrial power systems.
