3 HB General Characteristics HB is a DC High Speed Circuit Breaker (HSCB) mainly for rolling stock applications up to 1800VDC (Metro, Tram, LRV) Designed to Railway Standards, HB models can also be used in Light Rail Wayside current control, as well as inside Energy Conversion equipment and Industrial Power control applications. HB HSCB are based on a standardized body, that carries 2 different types of arc chutes for the nominal voltage differentiation when breaking the current. The main pole arrangement is designed for 1800VDC applications and with a smaller arc chute can be used in 900VDC applications. The HSCB is fully bidirectional without critical currents and with high breaking capability thanks to a metallic fins arc chute architecture and a very high speed of contacts during opening operation. The special shape of the arc chute limits the exit of gas allowing to reduce insulating distances. The activation coil uses an economizing circuit based on an electronic control card that allows to operate the HSCB without need of external control circuits. The electronic card is multivoltage input so that it can cover from 24Vdc to 110Vdc with the same product. The fixing interface can be customized to fit any installation requirement as well as the low voltage connector or wiring scheme. Customized busbars shapes are available on request. The HB series can be provided with box for roof or underframe installation or in a stand alone version for a flexible installation within an existing box. As the breaker can be installed horizontally, the standard box is an innovative solution to allow easy access and maintenance to all the main consumables. The arc chute half-box simply rotates up or down (for roof or underframe installation respectively) instantly allowing free access to the main breaker body and to the arc chute inner parts, for inspection or maintenance, without dismantling the unit from the train. The HB Breaker validation has been carried out to IEC standards, together with our co-development partner. The HB Breaker can be adjusted within 3 different overcurrent trip ranges, whereby the required trip level is then set at factory routine test. Pg 3/8

4 HB Models HB-HSCB follow a talking Part Number System to differentiate between its versions: Series Main digits Box Nominal Voltage Nominal Current Configuration digits Trip Range Version HB N A 0xx The P/N for HB HSCB has 12 digits: R B Sxx 8 main digits + 4 config digits U C Identifies standard / special version "0xx" = standard version, xx = revision index "Sxx" = special version, dedicated docs apply Indicates tripping range "A" = 0,9-1,3kA "C" = 1,8-3,6kA "B" = 1,3-1,8kA Indicates thermal current of the pole (@ 40 C) A A Indicates thermal current of each pole (@ 40 C) V V Indicates Installation mode N No Box R Box for Roof mounting U HB HSCB PART NUMBERING SYSTEM Box for Underfame mounting The main digits identify: 1. number of poles, 2. nominal voltage (external dimension of arc-chutes), 3. thermal current HB P/N & Docs The configuration digit are used to define 1. Trip Range 2. Standard / special versions (e.g. for auxiliary harnessing, special interface arrangements, etc) TP contactors product documentation is released and updated online at and includes: 1. A Product Chart PC for every applicable combination of main digits (standard versions), including all technical details, drawings, configuration information and spares part numbers. 2. A Validation Report VR, including all details of type tests carried out on HB range contactors 3. A Product Manual PM, with detailed installation and maintenance instructions Pg 4/8
