Thermal Overload Relay

TYPE: PK-1, PC-1, PC-2/3

TYPE PK - 1
TYPE PC - 1
TYPE PC - 2/3


    Salient Features

    • All relays are bearing  ISI mark  as per IS/IEC 60947 (Part-4/Section-1) .
    • Relay cover full range of current

        PK - 1    : 2.5 Amp to 14 Amp.
        PC - 1    : 1 Amp to 18 Amp.
        PC – 2/3 : 9 Amp to 42 Amp.

    • The triple pole bimetallic thermal overload relay is of the hand-reset type. It unmistakably indicates overload. A temperature compensation device prevents the relay from being affected by variation in ambient temperature.
    • The entire relay unit is housed in Bakelite enclosure and is accurately calibrated and individually tested on an automatic test bench. Setting can be adjusted by means of a pointer.
    • Satisfactory operation at all ambient temperatures from  –5 ᵒC  to  55 ᵒC with the help of temperature compensating device.
    • PK1, PC1, PC2/3 relays are manual reset type.
    • These relays are provided with auxiliary contacts having thermal capacity of 6A and 2A, AC-15 at 415V, 50Hz.
    • These relays are suitable for direct mounting on Type PC contactors.
    • PK1, PC1, and PC2/3 relays are suitable for trip class of 10A as per IS: 60947 (Part-4/Section-1).
    • Compact and most reliably designed.
