Overview

The nVent THERM26C (SKU: THERM26C) is a mechanical thermostat controller designed for precise temperature regulation in industrial enclosures. It registers ambient air temperature and reliably switches inductive and resistive loads via a snap-action contact. This unit features a control range of 5 to 60 degrees Celsius and operates at 230V AC. Its compact dimensions (2.64x1.97x1.50 inches / 67x50x38 mm) and lightweight design (2.00 oz / 60g) facilitate easy integration. The THERM26C is designed for vertical mounting on a standard 35 mm DIN rail (EN 60715). Key features include a bimetal sensor, switching capacity of 10 A resistive / 4 A inductive @ 230V AC (NC contact), and a durable UL94V-0 plastic housing. It offers IP20 protection. An optional integrated resistor (RF) can be connected to improve the switch temperature difference control. Compliant with CE standards, the THERM26C is ideal for maintaining optimal operating conditions for sensitive equipment in control cabinets and automation systems.

How to Install the THERM26C Temperature Controller

This guide provides step-by-step instructions for installing and configuring the THERM26C temperature controller in an electric cabinet.

Estimated time: 45m

Tools needed:

Screwdriver, Wire strippers, Multimeter

Supplies needed:

Mounting screws, Terminal connectors

  1. Mount the controller

    Secure the THERM26C controller to the upper area of the electric cabinet using the integrated clips. Ensure it is level and firmly attached.

  2. Connect the wiring

    Use heat-resistant cables to connect the thermostat to the appropriate terminals. Ensure that the clamping screws are fully tightened on terminals without connected wires.

  3. Configure the temperature settings

    Set the desired temperature on the controller, allowing for the maximum hysteresis of 5K +2/-3K. Verify the settings using a multimeter to ensure proper voltage levels.
