Utiliti Controls

Miniature Thermostat (SN-9)

We are one of the foremost Manufacturer, Exporter and Supplier of Miniature Thermostat (SN-9). The Miniature Thermostat (SN-9) provides high speed contact separation resulting in outstanding life cycle characteristics at electrical loads up to 8 amps. The Miniature Thermostat (SN-9) offered by us are well known for their reliability, compact size, versatile and cost effective design.

SN-9 of Utiliti controls is a product which is the smallest of disc thermostats. It is just 5mm X 14.5 mm in size. 100% factory inspected for continuity, function and contact resistance. PPS( polyproplene sulphide) base provides: low cost, high temperature capability, clean processing, high impact strength.

Designed for single- and threeâphase motors. Protects against overheating on all running conditions including: running overloads, increased ambient temperature, blocked motor ventilation, line voltage fluctuation, locked rotor, short circuit conditions etc.

Motor Protection
As a motor winding thermostat, the SN-9 can be mounted conveniently on the end turns of the motor windings. The small size and variety of available brackets afford flexibility in the method of attaching the thermostat. The hermetic construction allows the thermostat to withstand dipping and baking operations on the windings.
Automatic and Manual Reset
Automatic or manual reset systems may be obtained using these thermostats with either manual or automatic type motor starters. When more than one motor winding thermostat is used, they should be connected in series so that the opening of any one thermostat will actuate the controller and shut down the motor.
