MBR2-D Thermal Overload Relay
Application:
This series of thermal overload relay can be used in the circuit of 50Hz or 60Hz, rated insulation voltage 660V, rated current 0.1-93A for protecting the phase break when the electric motor is overload. The relay has different mechanism and temperature compensation & can be pluged in MBC1-D series AC contactor. It is the most advanced thermal relay in the nineties in the world. The products comply with IEC 60947-5.
Characteristics:
a. Fundamental parameter of the main circuit
(a). Rated insulation voltage 660V.
(b). Rated working current 25,36,93A separately.
(c). The regulator seal of rated setting current.
