N-Series N-Series CIRCUIT BREAKER Carling Technologies’ high-performance N-Series hydraulic-magnetic circuit breaker is ideally suited for the rigors and confined spaces of telecom and datacom power distribution units and rack systems. Its innovative, low profile design features easily accessible load and line terminals and sliding barriers for effortless installation. With the integration of an optional current transformer, the N-Series is capable of sensing power fluctuations down to a level of 1%. This optional capability provides precise current monitoring and reporting required for back billing of the actual power consumed by datacenter storage and routing devices. This feature also facilitates load adjustments and maximizes efficiency. A patent pending, flush-rocker actuator and push-to-reset guard offer additional protection against accidental switching. 1-2 poles; ratings: 1-30 amps up to 240 VAC, 277 VAC, 120/240 VAC; 22,000 Amps Max Interrupting Capacity; UL 489 Compliant Sliding Terminal Barriers; EN60947-2 Certified Resources: Download 3D CAD Files IGS IGS STP Watch Product Video Product Highlights: Typical Applications: 240 VAC, 277 VAC, 120/240 VAC UL 489 Compliant Sliding Terminal Barriers 22,000 Amps Max Interrupting Capacity 1 – 30 Amps Current Rating Optional Current Transformer EN60947-2 Certified Telecom/Datacom - PDU’s - Data Servers - Data Storage Carling Technologies, Inc. 60 Johnson Avenue, Plainville, CT 06062 Email: [email protected] Application Support: [email protected] Phone: 860.793.9281 Fax: 860.793.9231 www.carlingtech.com 2 | N-Series Circuit Breaker - Design Features N-Series DESIGN FEATURES CURRENT TRANSFORMER Remote current sensing via molex connector GRIDS (5x) Arc deionizing splitter plates that increase arc voltage for quick interrupt UPPER ARC RUNNER Optional, for 277 VAC rated breakers “ 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 Email: [email protected] Application Support: [email protected] Phone: (860) 793–9281 Fax: (860) 793–9231 www.carlingtech.com N-Series Circuit Breaker - General Specifications | 3 Electrical Current Metering Integrated current transformer. Measurement range: 1-30 Amps. Voltage output: 10mV per Amp according to the formula below: 2(Amp) ≤ I ≤ 30(Amp) V = 0.01× I ± 2% (with current metering codes 1 or 2) V = 0.01× I ±1% (with current metering codes 3 or 4) V V10 I I10 V10 I10 0.85% Where V=CT output in volts V10 =CT output in volts with I=I10 =10 (A); I=primary current in amperage (50/60 Hz). Phase shift between primary current and CT output is 0.25±0.25°. Maximum crest factor of primary current is 1.73. R1 shall be integrated in the breaker.
