TRIAC (Solid State Relay) Controllers
CCT Series Triac (SSR) Controllers
Up to 750 A, 1 or 3 Phases
Option: Overheat temperature sensor, and 120-1-60 control input
Technology
Cristal Controls solid state relay (SSR) is recommended for use with proportional temperature controllers and other applications where long life and solid state reliability are required. They provide ON-OFF control for any electrical resistance or HID lighting load.
The solid state relay control is suitable for all processes, that have either long or short-timed cycles. However, the shorter the cycle time, the better is your control.
Applications
- Resistive loads such as commercial duct heaters
- Lighting control
- Electronic boilers
- Electronic humidifiers
- Industrial & commercial ovens and furnaces
- Mine heaters
- Integrated circuit processing equipment
- Temperature control
- Replacement of magnetic or mercury contactors
Advantages
- Modulates the power nearest to the demand and reduces energy costs and power consumption
- Keeps the temperature closer to the desired set point for maximum comfort
- Higher precision, superior than contactors
- Fast adjustment and installation
- Zero-crossing operation and silent arcless switching
- Cycles once per second; very fast and quiet
- No maintenance, due to less mechanical parts failure
- Life expectation higher than 1 000 000 000 operations
- Does not create RFI (radio frequency interference) and will not affect sensitive electronic equipment
- Epoxy thermally protected, for humidity protection, overheat or contaminated environment protection
Specifications
- Accepts many input signals: 24 Vac, 3-32 Vdc (120-1 V and 240-1 V on request)
- Provides ON/OFF or pulse control for any electrical resistance or HID lights
- Security factor of 2, i.e. 600 V surge protected and built for 1200 V
- From 10 to 750 A and a maximum of 600 V
- 1 or 3-phase (on 3-phases applications, 3 legs cut-off is available)
- Mounted on an aluminium heat sink
- CSA and C US certified
- The controller must be mounted in a ventilated area
- 2-year exclusive warranty
Available options

Difference between SSR and SSR NEMA-4
NEMA-4 TRIACs are designed so the heat sink is completely outside the enclosure and all the electronic controls are located inside the enclosure. |
