Miniature Circuit Breaker · 2 Pole 2A 5kA · D Curve Supplementary Protector · Noark Electrical B1E2D2
What this product is for
The Noark Electrical B1E2D2 is a 2-pole UL 1077 miniature circuit breaker used for supplementary protection in control panels and equipment. It is rated 2A with a 5kA interrupting rating at 480Y/277VAC and uses a D-curve trip characteristic for circuits with higher inrush current.
Use for
Use this breaker for supplementary protection of control circuits, lighting circuits, business equipment, and appliances where a 2-pole 480Y/277VAC device is required. It is suited to 35 mm DIN rail panel layouts and applications where compact width matters.
Avoid for
Do not use this model where branch-circuit protection is required unless the equipment design specifically permits a UL 1077 supplementary protector. For feeder or branch protection, electricians typically need a breaker listed to branch-circuit standards rather than a supplementary protector.
Best for
Best for OEM equipment, industrial control panels, machinery, and commercial assemblies that need compact supplementary overcurrent protection with a D-curve response. This trip curve is commonly used where transformer, solenoid, or other inductive loads may create short inrush peaks.
Installed in
Installed in DIN rail control enclosures, machine panels, automation cabinets, and equipment assemblies. The breaker mounts on standard 35 mm DIN rail and has an 18 mm width per pole, for an overall width of approximately 1.42 in (36 mm).
Why this product exists
This product gives panel builders a compact supplementary protector for equipment-level overcurrent protection where a 2-pole 2A device is needed. It helps protect downstream components while fitting standard DIN rail layouts used across industrial and commercial equipment.
Compared with similar products
Compared with Noark branch-circuit breaker lines such as B1H or B1N, the B1E series is intended for supplementary protection under UL 1077. Compared with B- or C-curve versions, a D-curve breaker allows a higher instantaneous trip threshold, which is typically preferred for inductive loads with higher startup current. Actual suitability depends on the equipment design, load profile, and local electrical code.
