Product Code : SCL-EELE-12854
Indian Lab Suppliers supplies the Fuse, MCB & Bimetallic Relay Characteristics Trainer (Product ID: 12854) as part of its electronics engineering lab equipment range. It is a protection trainer for plotting the time-current characteristics of a fuse, an MCB and a bimetallic overload relay.
Quick Answer
A current injector, built from a 230 V / 1 A dimmer and a short-circuit transformer with 0-2-8 V / 12 A secondary taps, drives a chosen current through the 2 A rewireable fuse, 2 A MCB or 2 A bimetallic relay, while a 20 A AC ammeter and an elapsed-time counter with 1 ms resolution record the trip. A Hall-sensor zero-current detector panel (up to 20 A, 2.1 kV isolation) with a DC voltage transducer and relay contacts stops the timer. A control supply panel feeds DC to the signal panels and distributes single-phase AC through three 4 A MCBs, all on an aluminium profile panel system with 4 mm shrouded sockets. An air circuit breaker (400 A, 415 V) and an 11 kV SF6 breaker are offered as options for high-voltage labs; please confirm them at quotation, and apply test currents only under supervision.
