17 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.
AC Voltage Rating
C-Curve, 2-Pole UL1077 DIN Rail-Mount Supplementary Protectors
C-curve two-pole supplementary protectors trip instantaneously when the current load exceeds five to ten times the rating of the device. These breakers mount on standard 35mm DIN rail and are UL1077 listed for use as supplementary protection from damage caused by overcurrents and short circuits. They protect two circuits at the same time and are used when protection against medium-level short circuit faults is desired, such as in control panels, lighting, and coils.

D-Curve, 2-Pole UL1077 DIN Rail-Mount Supplementary Protectors
D-curve two-pole supplementary protectors trip instantaneously when the current load exceeds ten to 20 times the rating of the device. These breakers mount on standard 35mm DIN rail and are UL1077 listed for use as supplementary protection from damage caused by overcurrents and short circuits. They protect two circuits at the same time and are used when protection against high-level short circuit faults is desired, such as in motors, transformers, and power supplies.

B-Curve, 2-Pole UL1077 DIN Rail-Mount Supplementary Protectors
B-curve two-pole supplementary protectors trip instantaneously when the current load exceeds three to five times the rating of the device. These breakers mount on standard 35mm DIN rail and are UL1077 listed for use as supplementary protection from damage caused by overcurrents and short circuits. They protect two circuits at the same time and are used when protection against low-level short circuit faults is desired, such as in PLC wiring, lighting, and appliances.
