Product Description

JR28-200 New Original 200A thermal Over Current Protection relay thermal relays types

Product Description

 

    This series of thermal relay can be used in the circuit of 50Hz or 60Hz,rated insulation

voltage 660V,rated current 0.1-96A for protecting the phase break when the electric motor is

overload. The relay has different mechanism and temperature compensation & can be

plugged in LC1-D series AC contactor.It is the most advanced thermal relay in the nineties in the world.

 

      A.Fundamental parameter of the main circuit
(a).Rated insulation voltage 660V.
(b).Rated working current 25,36,93A separately.
