Spectra Plus - Introduction02Current limiting1The limiting capacity of a circuit breaker is the expression of the breaker’s capacity.In the event of a short circuit, it reduces the let through current to a lower value than theprospective fault current.This characteristic is expressed by the following limiting curves:1. Icc unlimited peak2. Icc limited peak (actual)2The great limiting capacity of Spectra Plus circuit breaker is a result of the optimalcombination of:A light moving part, reducing inertia.A strong current loop, to generate maximum force of repulsion.A slot motor with strong electro-magnetic field to accelerate the opening of thecontact.Contact materials combining good conductivity and high durability.An arc chamber combining a high energy absorption capacity, speed in breaking ofarc and cooling of gases.This combination has enabled an exceptional breaking capacity/volume ratio. Theuse of Spectra Plus circuit breaker enables a great reduction in stresses that normallydevelop during a short-circuit:Reduction in thermal constraints in conductors, increasing their life.Reduction in mechanical constraints due to the reduction of the electrodynamicforces of repulsion between conductors, which reduces the risk of deformation orrupture of the wiring.Reduction in electro-magnetic effects. The electro-magnetic field reduces and causesless damage to neighboring devices and sensors.UseSpectra Plus circuit breakers provide a solution for standard and high performance levelsupto 50kA breaking capacity in 3 frames SE160, SF250 & SG400/630.Suitability for visible isolationSpectra Plus circuit breakers are ideal for fully visible isolation selection. With the handlefree, the indication “open” (green display) is only possible when the main contacts areseparated by a distance of >20mm. Spectra Plus circuit breaker conforms to standards:IEC947-3, IS13947-3 recommended for isolation.Double forward facing insulationSpectra Plus circuit breakers are provided with forward facing spaces designed forinsertion of internal electrical auxiliaries. These spaces are completely insulated from thepower circuit.Accreditation / CertificationIEC947-2, EN60 947.2, IS13947,Lloyd’s Register of Shipping, RINA.

03 Spectra Plus - IntroductionHigh performance electronic protectionThe current sensor output signal for each phase is sampled more than 30 times percycle in order to establish the true RMS value, independent of the network, the natureof the load and the environment of the installation. Hence, Spectra Plus guarantees“correct protection”.Power sourceThe power source can be connected either from upline or downline of the Spectra Pluscircuit breaker, and up to the maximum voltage for use (690V).OrientationA fixed circuit breaker can be mounted as follows:

Spectra Plus - Introduction04Electrical auxiliariesBA bell alarms, AS auxiliary ‘ON/OFF’ switches, ST voltmetric shunt releases and UVundervoltage releases are common to all Spectra circuit breakers. e.g. an AS auxiliary‘ON/OFF’ switch can be installed equally well on an SE 160 or SG 630 circuit breaker.Thus it is not necessary to specify the type of circuit breaker. Only the release voltageand the type of contact (standard or low level) has to be indicated with the order.AssemblyAs this is intended for installation in compartments that are accesssible from thefront, it is not necessary to take off the cover of the circuit breaker.Left-hand compartmentOption of connecting UV or ST releases plus 3 pole BA. 1 or 2 additional AS contactscan be connected to 4 pole SG400 to SG630 circuit breaker (an extra socket isprovided for this).On each circuit breaker, ducts for the wiring are provided enabling the passage of thecables to the right, left, or to the rear side of the device, without increasing its originaldimensions.Right-hand compartmentOption of connecting 1 or 2 AS auxiliary switches.On each circuit breaker, ducts for the wiring are provided enabling the passage of thecables to the right, left, or to the rear side of the device, without increasing its originaldimensions.Maximum possibilities for auxilliariesCircuit Breaker 3P 4PAS 2 2BA 1 1ST or UV 1 1
