1-Pole, UL1077 DIN-Rail Mount Supplementary Protectors

42 products
One-pole supplementary protectors are used in a single circuit to interrupt currents in the event of an overload. 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, and control power transformers.

DC-Only Rated, 1-Pole UL1077 DIN Rail-Mount Supplementary Protectors

DC-Only Rated, 1-Pole UL1077 DIN Rail-Mount Supplementary Protectors
DC-only one-pole supplementary protectors mount on standard 35mm DIN rail and provide more support than protectors used for both AC and DC voltage applications. These protectors are used with a single circuit 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.
