FEATURES/BENEFITS
• Three-phase solid-state relay in a compact SIP
package
• High-temperature plastic housing for mechanical
ruggedness
• Tight zero-cross window for low EMI
• Exposed ceramic baseplate for reduced thermal
resistance
DESCRIPTION
The Series C3P three-phase AC solid-state relays
are designed to control medium amounts of power in
three-phase applications. Optical isolation ensures
complete protection of the C3P’s control circuit from
load transients. The C3P’s compact plastic housing
provides a low-cost alternative to large metallic three-
phase contactors. The C3P is designed with
heatsinking in mind. The ceramic baseplate provides
excellent thermal performance. The relay’s tight zero-
cross window greatly reduces EMI.
APPLICATIONS
• Heating control
• HVAC controls
• Light/Lamp control
• Three-phase AC loads
