3NT01L-H7897

3NT | SERIES FIXED TEMPERATURE THERMOSTATS Introduction Automatic reset thermostat designed to meet your specific application requirements. Its patented and tamper proof snap action bi-metal disc provides reliable and repeatable switch actuation. The 3NT is suitable for electrical loads ranging from dry circuits to 10A @ 240 VAC. The core of the 3NT is the proven 1NT thermostat. Recognized by UL/CSA and KEMA/ENEC agencies, hundreds of millions of the 1NT device are in the field today used in a variety of HVAC, appliance, automotive and specialty applications. Manufactured at ISO 9001 certified manufacturing sites, its dry seal allows direct integration of the thermostat into a wire harness eliminating the need for extra connections. Features • Automatic reset • Small and easy to mount • Fast thermal response • Innovative dry seal design - protects from moisture and dust • Reliable 100K cycle life • High temperature - to 275ºF (135ºC) Applications • HVAC • Commercial • Dehumidifiers • Freezers • Heat pumps • Ice makers • Refrigerators • Condensing or moist environments SPECIFICATIONS Agency UL (USA, Canada) Electrical Ratings ENEC (Europe) Operating Temperature Ambient Temperature Temperature rating Minimum Nominal Temperature Differential Dielectric Strength Standard Wire Leads Cycles x1000 Volts FLA LRA 100 100 30 30 100 120 Vac 240 Vac 120 Vac 240 Vac 30 Vdc 5.8 2.9 10.0 10.0 34.8 17.4 40.0 40.0 30 240 Vac Amps (resistive) VA 10 10 125 125 1 16 -20 to 135ºC (-4 to 275ºF) -40ºC to maximum wire lead insulation PVC - 105ºC XLP - 125ºC (Allow 15ºC de-rating below wire insulation rating at maximum 10A current) 8ºC (15ºF) 750 Vrms 1500 Vrms terminals to case 18 AWG (1/32” or 1/16” wall thickness in either 105°C PVC or 125°C XLPE) 16 AWG (1/32” wall thickness in 105°C PVC) Page 1 Copyright © 2018 Sensata Technologies, Inc. www.sensata.com 3NT DRY SEAL DESIGN HOUSING LOCKING CONNECTORS O-RING WIRE LEAD ASSEMBLY 1NT THERMOSTAT 3NT CUP Important Notice: The 3NT is not hermetically sealed, and should not be submerged in liquid.
