Product Description

The RANCO A30-2311 is a constant differential defrost cycle control, a single-pole single-throw (SPST) device with a 30-inch capillary. It operates at 120/240V AC and is designed for defrost cycle management in industrial equipment.

Frequently Asked Questions

What is the RANCO A30-2311 defrost cycle control used for?

The RANCO A30-2311 is a constant differential defrost cycle control used in industrial refrigeration and HVAC systems. It manages defrost cycles by sensing temperature via its 30-inch capillary and switching a single-pole single-throw (SPST) contact at 120/240V AC to terminate defrost and resume normal cooling.

What are the specifications of the RANCO A30-2311?

The RANCO A30-2311 is a constant differential defrost control with SPST switch action, a 30-inch capillary, and a voltage rating of 120/240V AC. It is designed for defrost cycle management in industrial equipment. For detailed electrical ratings and differential settings, consult the manufacturer's datasheet.
