Timer Relay / Industrial Control Relay

MK-03 Phase Failure and Phase Sequence Relay

The MK-03 phase monitoring relay supervises phase failure and phase sequence in three-phase control systems. Its changeover output can be incorporated into machinery control circuits where the supply condition must be checked before operation.

Model

MK-03

Product Type

Three-phase phase-failure and phase-sequence monitoring relay

Application Focus

Three-phase power monitoring and motor-control protection circuits

MK-03 phase failure and phase sequence relay

Buyer Overview

KANGGE ELECTRIC supplies the MK-03 series for importers, distributors, panel builders, machinery manufacturers, contractors and OEM electrical-equipment buyers.

MK-03 Quick Selection: Confirm the exact model, rated voltage, three-wire or four-wire connection, output-contact requirement, application and quantity before quotation.

Product Advantages

•Phase failure and sequence protection helps define the MK-03 application; check the complete wiring and control-circuit requirements before selection.
•The 50/60Hz three-phase relay has a listed operating range of (0.9-1.1) x Un.
•The single changeover monitoring relay output is rated at 8A and 2000VA for a resistive load.
•For phase relay voltage selection, 120V AC and 220V AC use a neutral connection, while 380V AC and 440V AC use three wires.
