Solid State Relay Carlo Gavazzi RA4450-D08 (50A, 440V AC, Control 3-32V DC)

Solid State Relay Carlo Gavazzi RA4450-D08 (50A, 440V AC, Control 3-32V DC)

Product Description

Industrial-grade, single-phase Solid State Relay (SSR) manufactured by the renowned European brand Carlo Gavazzi. This device is designed for contactless switching of high-power alternating current (AC) loads via a direct current (DC) control signal. Featuring a Zero Switching (Zero Cross) function, it significantly minimizes electromagnetic interference (EMI) and extends the operational lifetime of both the relay and the connected equipment. The housing is built in the standard "hockey puck" form factor with a heavy-duty metal baseplate for efficient heat dissipation.
