2-Pole, UL1077 DIN Rail-Mount Supplementary Protectors
Available8 products
Two-pole supplementary protectors protect two circuits from current overloads at the same time. They're UL1077 listed for use as extra protection from electrical damage for devices that already have branch circuit protection or where branch circuit protection isn't required. These protectors follow trip curves to determine when they will interrupt the current. If the current exceeds a device's rating up to a certain factor, the circuit breaker will have a delayed trip to prevent nuisance tripping. If the current exceeds the device's rating at or above that factor, it will immediately trip. They're mounted on standard 35mm DIN rail in applications like luminaires, appliances, control circuits, control power transformers, and other electrical equipment.

DC-Only Rated, 2-Pole UL1077 DIN Rail-Mount Supplementary Protectors
DC-only two-pole supplementary protectors mount on standard 35mm DIN rail and provide more support than protectors used for both AC and DC voltage applications. They protect two circuits at the same time in semi-conductor machines, communication equipment, process control panels, computers, and other DC-powered equipment. They're UL1077 listed for use as supplementary protection from damage caused by overcurrents and short circuits.
