MPCB-Testing-Equipments-Thermal-Trip-Test
PC Based Thermal Trip Test System for Motor Protection Circuit Breaker- 30 Station

MPCB Thermal Trip Test Bench -
PC Based (30 stations)

 The SCR Elektroniks make an MPCB (Motor Protection Circuit Breaker) Testing Equipment is a high-precision testing solution designed to evaluate, verify, and calibrate the thermal-magnetic protection mechanisms of Motor Protection Circuit Breakers. Built in strict accordance with international standards primarily IEC 60947-2 (Low-Voltage Switchgear: Circuit Breakers) and IEC 60947-4-1 (Contactors and Motor-Starters) it ensures that MPCBs reliably trip during critical overload and short-circuit fault conditions.
This is a LabVIEW – PC based Test System designed to tests 30 MPCBs for Overload Current Trip.
