This series of thermal relays can be used in the circuit (frequency 50or60HZ, rated insulation voltage 660V, rated current 0.1-96A) for protecting the phase break when the electric motor is overload.
The relays have different mechanism and temperature compensation & can be plugged in KL1-D series AC contactor. It is the most advanced thermal relay in the nineties in the world.
a. Fundamental parameter of the main circuit:The relays have different mechanism and temperature compensation & can be plugged in KL1-D series AC contactor. It is the most advanced thermal relay in the nineties in the world.
(a). Rated insulation voltage 660V
(b). Rated working current 25, 36, 93A separately
(c). The regulator seal of rated setting current and setting.
(d). Current of the thermal component (see list 1)
b. Auxiliary circuit
(a). There is one pair of NO/and N/C contact with electric insulation.
(b). Rated insulation voltage 500V
(c). Rated frequency 50-60HZ.
(d). Use group, rated working voltage, appoint thermal current and rated current.
