(1) Electric welding machine, electric
(2) Electric equipment,
(3) Electric products,
(4) Steam heater
(5) High power machinery equipment
(6) Demand Water Heaters
4. Attention of KSD302 large current thermostat
(1) By using the contact temperature type when installed, should
make metal cap surface adhere is accused of mounting surface of the
appliance.
(2) When installation shall not cover surface pressure deformation,
lest affect performance.
(3) To prevent leakage, when using, can't let the fluid
infiltration within the thermostat, lest affect electric
reliability.
(4) This product for bipolar type wiring way, when using, according
to mark symbol, correct connection.
The product should be a headscarf in relative humidity is less than
90%, the environment temperature below 40 ℃ ventilation, clean,
dry, no corrosive gas storage in the warehouse.
Thread copper head thermostat / Thread copper head thermal
protector
1. Thread copper head thermostat’s Principle and structure
Utilize overseas high-quality dished dual metallic piece as
temperature gathering element, will switch installed in water
temperature the temperature sensitive parts, dynamic collection the
temperature change of the water tank, through the disc in metal
temperature deformation, and transient temperature points in
beating principle, with institutions in the role of the two
contacts quickly switched on, start fan, cooling water of the
water, of automobile engine have security role.
2. Thread copper head thermal protector’s use conditions
2.1. relative humidity in + 20 ℃ environment give 95%
2.2. Atmospheric pressure Kpa 86-106
2.3. Working location: any
