Multi-Amp SR-90 Universal Protective Relay Test Set

The Multi-Amp SR-90 Universal Protective Relay Test Set is a multi-purpose, two-piece test set that accurately and efficiently tests electromechanical and solid-state protective relays.It is field portable and has sufficient power (1.4 kVA) for testing any protective device requiring up to 420 amperes.

The SR-90 is designed so the main control section (Unit 1) and the auxiliary section (Unit 2) can be used independently for testing simple protective devices. To perform testing of more complex relays, Units 1 and 2 are easily interconnected to provide four simultaneous outputs of ac current or ac voltage, and dc current or DC voltage.

Multi-Amp SR-90 Applications:

The Multi-Amp SR-90 is designed for calibrating, acceptance testing and troubleshooting of protective relays, small molded-case circuit breakers and motor overload relays, and for timing circuit breakers.

This test set is ideal for field, shop or laboratory use at utilities, manufacturing plants, commercial complexes or other facilities that perform preventive maintenance on electrical equipment.
