Product Description P/N: DC21-60C0-0000
Description
The Watlow DC21-60C0-0000 is a solid-state power controller for switching three-phase electric heating loads through two controlled legs. It accepts a low-voltage direct current command and uses zero-cross switching to control loads operating from 277 to 600 volts alternating current.

Information About DC21-60C0-0000
The DC21-60C0-0000 is a DIN-A-MITE Style C controller with integrated power switching components and a fan-cooled heat sink. Its construction incorporates four silicon-controlled rectifiers arranged to switch two legs of a three-phase supply. The control input connects to compatible temperature controllers or other devices providing a 4.5–32-volt direct current contactor signal. Designed for industrial heating panels, this configuration supports DIN-rail or panel installation and has no alarm option fitted.
Key Features:
- Three-Phase Control: Switches two supply legs to regulate power to compatible three-phase heating loads.
- Semiconductor Switching: Uses four silicon-controlled rectifiers for operation without mechanical switching contacts.
- Zero-Cross Operation: Switches near the alternating current voltage zero crossing in response to the command signal.
- Direct Current Input: Accepts a 4.5–32-volt on/off control signal from compatible external equipment.
- Load Current Capacity: Rated for 65 amperes per controlled leg at an ambient temperature of 50°C.
- Forced-Air Cooling: Incorporates a heat sink and a fan requiring a 120-volt alternating current supply.
- Mounting Options: Supports installation on a DIN rail or directly on a panel.
The DC21-60C0-0000 delivers the reliability and precision required for controlled electrical power switching in industrial heating systems.
