DC Overcurrent Protection Relay

The type 76 DC overcurrent relay is designed to be one of the most widely used protective overcurrent devices on the market. This device sees use across the transportation industry. As a device that has been successfully used across every major transportation system, this product delivers protection against trolley wires, third rails, substations, and feeder controls. As a design for remote overload conditions as well as intermediate overload conditions, this is a product that can prevent failures.

As a device that can also prevent severe overloads, it comes with a solid-state design with extremely rugged construction. As low maintenance and dependable solution, this is a relay that can perform even under the most adverse conditions.

Features

LED meters produce easy and accurate readout.

A construction this designed in a modular format for a variety of fits. A draw-out construction for reliability.

Detector channels can include a rate of rise, long-time overcurrent, short-term overcurrent and instant overcurrent charge protection.

The device can be used with any shut off an internal power supply ensures there can be auto compensation for DC inputs. Calibration controls on the device allow for preset thresholds and a series of delays within every protective channel. These delays ensure there can be verified accuracy with any shut off and full verification on any failure.

The device works on negative conductors and positive conductors on DC networks and includes easy field calibration solutions.

A DC overcurrent relay in type 76 format remains an insulated current monitor that works for both negative and positive conductors. This is an essential piece of technology for a standalone relay. This device is also widely compatible with other types of safety relays. It works in conjunction with the tightly to automatic reclosing relay and in combination with other reclose relays.

When used in conjunction with one of these relays the device will automatically interrupt fault and reclose in order to continue service. Control panel functions are calibrated in millivolts to ensure that the relay can be widely compatible with any shunt. Built-in calibration components on the device also ensure accurate field calibration. The relay is designed to be set up in just a few minutes with widely accurate readouts and protection. Each channel comes with preset items to ensure fast setup.
