Noark Miniature Circuit Breaker UL 489

These branch circuit breakers are available in two terminal configurations: standard box terminals that accept multiple conductors and ring-tongue terminals. All breakers mount on standard 35 mm DIN rail. Bus connectors and feeder terminal facilitate mounting and wiring of multiple miniature circuit breaker arrays in control panel assemblies. Breakers can also be reverse feed.

Specifications:
· Canadian Standards Association (CSA) C22.2 No. 5-02 standard for branch circuit protection.
· UL 489A requirements covering single pole DC circuit breakers intended for use as a branch circuit
over current and short circuit protection in communications equipment
· UL 486 standard for connection terminals which allows the user to apply field wiring directly to the breaker.
· IEC 60947-2 standard for industrial applications of circuit protection.
· These devices are RoHS compliant.
· Dinrail Mount.
· Captive Terminal Screws.
· B, C, D Curves to 20 AMPS.
· 1,2,3 Poles.
· Maximum 480VAC (2 and 3 POLE), 277VAC Single Pole.
· 14-4 AWG Termination Wire Size.

CURVE INFORMATION:
· B (3-5 In): Protection for people and big length cables in TN and IT system.
· C (5-10 In): Protecting for resistive and inductive loads with low inrush current.
· D (10-14 In): Protecting for circuits which supply loads with high inrush current at the circuit closing (LV/LV transformers, breakdown lamps).
·D Curve is for industrial area, it is slowest.
