Product Description

The Myers Power Products High Speed DC Trip Unit offers state-of-the-art, microcontroller-based overcurrent protection for DC circuits in traction power and other applications. The High Speed DC Trip Unit features a Hall effect sensor, which provides both directional and bi-directional current sensing; a front LED panel that allows settings to be programmed in either amps or seconds and displays last trip data; a momentary alarm relay; and an integrated 16-character ammeter. Optional features include supervisory (remote) trip capabilities and integrated lockout relay.

The Myers High Speed DC Trip Unit is integrated into new FBK Breakers and sold as an upgrade for existing FBK Breakers, replacing the original ABB trip unit. The High Speed DC Trip Unit is easily replaceable, plugging directly into the existing wiring harness using the instructions below.
