N-Series Hydraulic-Magnetic Circuit Breaker P ROD UC T W E BP A GE request sample, configure part, watch video Low Profile Datacom/Telecom Applications The N-Series is a full-featured hydraulic-magnetic circuit breaker packaged in an innovative low profile design to meet the smaller size requirements of datacom/telecom power distribution units and rack systems. Its features include easy access line and load terminals with UL 489 compliant sliding terminal barriers, an optional current transformer capable of sensing current down to a level of 1%, and a patented flush rocker actuator with push-toreset guard to protect against inadvertent actuation. The N-Series is available as a one or two pole configuration with ratings from 1 to 30 amps, up to 277VAC for one pole or 120/240VAC for two poles with a max IC of 22,000 amps. 1-2 1-30 120/240 22,000 Amps Poles Amps Typical Applications ∙ Power Distribution Units www.carlingtech.com ∙ Data Servers 860.793.9281 ∙ Data Storage sales@carlingtech.com VAC Max Interrupting Capacity Design Features CURRENT TRANSFORMER Remote current sensing via Molex® connector UPPER ARC RUNNER Optional, for 277 VAC rated breakers GRIDS (5x) Arc deionizing splitter plates that increase arc voltage for quick interrupt “ LOAD “ “ LINE “ TERMINAL Allows for easy hook-up of wires on both sides of the breaker LOWER ARC RUNNER Motivates arc off of the stationary contact SLIDING TERMINAL BARRIERS 2. Tech Specs Environmental Electrical Dielectric Strength Current Ratings UL, CSA-1960V 50/60 Hz for one minute between all electrically isolated terminals.
