Sensata | Crydom Solid-State Relay, 8pF I/O Capacitance, 4000Vrms Dielectric Strength - HA Series - HA4875

Switch to this solid-state relay from Sensata | Crydom for steady and safe control of your electrical loads. It opens and closes your circuit when its integrated sensor receives a control signal, eliminating the need for manual operation. As it has no moving parts, this component is immune to mechanical wear, so you can take maintenance off your to-do list. It's a sure fit for small spaces, thanks to its compact dimensions of 57.3 (L) x 44.5 (W) x 22.6mm (D). This device is a reliable workmate for managing large-scale lighting systems and motors in manufacturing applications.

Features & Benefits

• Aluminium baseplate is resistant to corrosion and impact

• Wide operating temperature range between -40°C and +80°C to stand up to demanding conditions

• Dielectric strength of 4000Vrms shows it offers effective insulation to prevent electrical hazards

• Low I/O capacitance of 8pF for high-integrity signal transmission

• Stops burning in 10 seconds or less for safety in the event of a fire
