  • Product description and use method:


    □ XRNC, BR1, BR2, BRW, BRN, BRW2, BR, RN, RNYI, RNG, RW type fuses are used for the internal fault protection of a single capacitor in a star-connected capacitor combination in power systems of 10KV and below. Can reliably and quickly disconnect the faulty capacitor. In order to avoid the explosion accident that may be caused by the breakdown of components inside the capacitor, the power grid will continue to operate safely.

    This product is suitable for indoor AC 50Hz, rated voltage 3.6, 7.2, 12KV system as short circuit protection of power capacitor bank. Under the specified conditions of use, the fuse can reliably break any current between the melting current and the breaking current Fault current.
