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 threephase 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

NOTES
(*) Relay built with back-to-back thyristors and high performance
optocouplers. Relays have been tested at Teledyne Relays with frequencies
higher than 2000 Hz on a resistive load.
For other loads the user will have to check functionality in nal application.
