Nonstock 11100.9-00 Thermostat Switch 15A Nc Din Rail

Product Description

The NONSTOCK 11100.9-00 is a KTO 111 mechanical thermostat switch with a normally closed (NC) configuration, designed for industrial and commercial temperature control applications. Rated at 15 amps at 120VAC and 10 amps at 250VAC, it features an adjustable setpoint range of 32 degrees F to 140 degrees F. The NC contact opens when temperature rises above the setpoint, making it well suited for controlling electric heaters or triggering signal transmitters when temperature drops below a defined threshold. Push-in terminals secure supply lines and prevent accidental disconnection during operation.

This thermostat switch is intended for use in enclosure thermal management, heater control circuits, and process monitoring systems where a mechanically operated NC contact is required. It mounts on standard DIN rail, fitting cleanly into electrical panels and control cabinets. Typical installers include industrial electricians, panel builders, and controls technicians working on heating control or equipment protection circuits. The adjustable range covers common low-to-moderate temperature monitoring applications in both HVAC auxiliary systems and light industrial environments.

Key Features

• Normally closed contact opens on temperature rise for heater control or under-temperature signal switching
• Adjustable setpoint range from 32 degrees F to 140 degrees F
• Dual voltage rating: 15A at 120VAC and 10A at 250VAC
• DIN rail mount for straightforward integration into standard control panels
• Push-in terminals lock supply lines in place, reducing risk of loose connections
• Mechanical operation with no external power required for switching function

Compatibility

Designed as an OEM-style replacement or direct-fit thermostat switch for DIN rail-mounted control panel assemblies requiring a normally closed, adjustable mechanical temperature switch.

Installation Notes

Installation should be performed by a qualified electrician following applicable NEC requirements. De-energize all circuits in the panel before mounting or wiring the switch. Verify that the supply line amperage does not exceed the rated load for the operating voltage before connecting. Confirm DIN rail is properly grounded and that push-in terminal connections are fully seated before restoring power.
