When it’s necessary to test circuit breakers and protective relay systems, a secondary injection test set is the main piece of electrical test equipment companies utilize. Secondary injection testing differs from the standard primary injection testing method in that there is no current flowing and contacts remain closed during the testing process.
Because trip units serve a critical role in electrical systems, companies must actively test them to prevent electrical faults from causing equipment failure or accidents, and testing pinpoints any defects in the trip unit or other protective systems ensuring that systems are functioning normally.
A full function test kit, the Square D by Schneider S33595 Secondary Injection Test Set is designed to perform tests on Micrologic, NT and STR Trip units.
The Square D S33595 consists of a signal-injection box which can be used alone or with a supporting personal computer (PC). The optional test kit software is compatible with Windows® 95, 98 and Windows NT® operating systems.
