Product Description P/N: DB20-60C0-0000
Description
The Watlow DB20-60C0-0000 is a solid-state power controller that switches three-phase resistive heating loads through two controlled supply legs. Its direct current command input and zero-cross operation provide on/off heater control, while an integrated heat sink dissipates heat through natural convection.

Information About DB20-60C0-0000
The DB20-60C0-0000 is a DIN-A-MITE Style B controller designed for installation in industrial equipment panels. Four silicon-controlled rectifiers form its power switching assembly, eliminating mechanical switching contacts. The unit accepts commands from compatible temperature controllers providing a 4.5–32-volt direct current signal. This standard configuration supports DIN-rail or panel mounting and operates without an optional alarm output.
Key Features:
- Three-Phase Load Switching: Controls two supply legs for compatible three-phase electric heating circuits.
- Zero-Cross Control: Switches near the alternating current voltage zero crossing in response to an on/off command.
- Natural Convection: Uses passive heat dissipation without a cooling fan or separate fan supply.
- Semiconductor Construction: Employs four silicon-controlled rectifiers for repeated switching without contact wear.
- Direct Current Interface: Accepts a 4.5–32-volt control signal from compatible external equipment.
- Integrated Heat Sink: Combines the power switching assembly and cooling structure in one package.
- Flexible Installation: Fits a standard DIN rail or mounts directly to a panel.
The DB20-60C0-0000 delivers the reliability and precision required for commanded power switching in industrial resistance heating systems.
