Test Equipments for Thermal Overload Relays

We design and manufacture test equipments and automation solutions for testing and production of Thermal Over-load Relays.
Some of our recent solutions are listed here. These facilitate testing of relays as per IEC 60947-4-1 and others. Please write to us for more details.

PC based Thermal Trip Routine (production) test bench for Overload Relays

This is a multi-station thermal trip (characterisitics) routine (production) test system for Overlaod relays. It is available with 1, 6, 12, 24 or 48 stations. The entire test sequence is programmed and is controlled by customisable Testware running on PC. The operator has to select the type of relay (model or SAP code) to be tested once on starting the bench, and then just load the relays in the jigs (electro-pneumatic fixtures).
The accompanying PC based Testware is intuitive, has secured database and exports reports easily for statistical analysis such as pareto analysis, bell-curve etc.

• The system is available with individual current source available in different ranges from DC 0.2A to 100A/24V max (with regulation of 0.2%).
• Specially designed jigs for ease and operator safety (can be integrated on an automated assembly).
• No risk to operator as max voltage is 24V DC; does not require skilled operator.
• Ergonomic design; Pneumatic fixtures to quick load/unload all stations by one operator.
• Fully scalable to suit any production load : 1 Station, 2 Station ...... 48 Stations.
• Reporting for Data Analysis.
• Modular design for easy maintenance & to ensure zero break down.
• Lower power consumption as each station goes in sleep mode automatically after trip.
