Control voltage is 120VAC or 230VAC or 24-48VDC or 125VDC. Check circuit breaker front cover for Trip Unit power requirements. A remote Stack Light, Annunciator Panel or other remote indication device can be connected to verify that the Digitrip is in the Maintenance Mode. Relay in GF Alarm/PS Module closes when Maintenance Mode is armed.
The trip units operate the basic overcurrent protection functions through current sensors mounted in the breaker, eliminating the need for external control power. When a breaker trips, an LED on the trip unit indicates the cause of the trip. Each model offers unique features: - 520: Protection only. - 520M: Current metering.
This instruction book specifically covers the application of Digitrip 520/520M units installed in Series NRX circuit breakers. The Digitrip trip units are circuit breaker subsystems that provide the protective functions of a circuit breaker. The primary function of the trip unit is circuit protection but some models offer additional features ...

This protection is functional even when Instantaneous is set to the OFF position. For Standard Frame rated 3200A and less of MDSC type, an additional Instantaneous Trip Module is provided in the breaker set to pickup at 160.0kA Instantaneous peak current level (85kA symmetrical RMS with 15% power factor).
