Test Setup for Screwless Terminals

Screwless Terminal Testing for Switches & Sockets

Two test systems to check screwless terminals: the Electric and Thermal Stress System checks the effect of current and heat cycling, and the Deflection Test checks the effect of load and rotation on the terminal. Both are designed as per IS 1293 and IS 3854.

Voltage

Range 0-99.9 mV, resolution 0.1 mV, accuracy 0.5% ± 1 count.

Timer

ON and OFF time 0-99 min 59 sec each (preset 30 min), resolution 1 sec.

Counter

0-9999 cycles (preset 192), resolution 1 count.

Data Logging

Logs date, time and voltage at 1 to 50 hr intervals (preset 24 hr). Saved direct to pen drive, viewable on PC.

General

Supply 230 V ± 10%, 50 Hz. Painted MS panel, labelled meters and LEDs, master ON / OFF switch. Calibration: NABL.

Deflection Test

Checks the effect of load and rotation on screwless terminals.

Current

Specified current passed through the terminal under test, 0-30.0 A variable, resolution 0.1 A, accuracy 0.5% ± 1 count. Variation within 5% using suitable resistance.

Voltage

Voltage drop across the terminal measured over 0-99.9 mV, resolution 0.1 mV, accuracy 0.5% ± 1 count.

Loads

Applied through weights: 0.25 N, 0.5 N, 1 N.

Directions

Assembly mounted on different holes to check voltage drop in 12 directions, 30° apart.

Mechanical Assembly

Mounts the terminal under test, allows insertion and removal of conductors of suitable length and cross section, and clamps the voltage measuring points.

General

All units in a single assembly. Supply 230 V ± 10%, 50 Hz. Painted MS panel. Calibration: NABL.
