The fourth engineering type 76 overcurrent relay is one of the most widely used overcurrent devices in the transit industry today. This device is so widely used for protection in the transit industry that it has worked to protect against many accidents over its history of deployment. Now a required technology in many transit systems worldwide, this device supports bolted faults, arcing faults, severe overload, and more.
Built-in a solid-state design with rugged construction, this is a low-maintenance option for monitoring adverse conditions and ensuring that overcurrent charges can be detected easily. The unique bi-directional mode indicating field switchable monitor is configured in this device.
Detected channels include instant overcurrent ranges of 10 to 300 mV, and short-term overcurrent ranges of can do 110 mV. With longtime overcurrent and rate of rise technology, the calibration controls allow for a preset thrash and an easy internal power supply that operates on a massive range of DC inputs. The device can be used without any shots and works with positive and negative conductors in DC networks.
These devices offer field calibration from skilled engineers that can set them up to suit the requirements of any worldwide rail system. The system is insulated with a current monitor and overcurrent relay, and in the type 76 version, it can coordinate with other monitors, such as the type LXXXII automatic reclosing relay. Controls can be calibrated to the mini volt to ensure each channel has its own feeder current settings and support.
