ART815650.book Page 19 Lundi, 6. février 2006 10:18 10 Functions and characteristics General characteristics 0 DB101079 DB101078 Compliance with standards The mark indicates that the product meets both US and Canadian safety requirements. Vigirex relays are designed to comply with the following standards: b IEC/EN 60755: general rules for residual-current protection devices b IEC/EN 60947-2 annex M: low-voltage switchgear and controlgear, part 2 (circuit breakers) b IEC/EN 60947-5-1: low-voltage switchgear and controlgear, part 5-1 (electromechanical devices) b IEC/EN 61000-4-2: electrostatic-discharge immunity test b IEC/EN 61000-4-3: radiated, radio-frequency, electromagnetic-field immunity test b IEC/EN 61000-4-4: electrical fast transient/burst immunity test b IEC/EN 61000-4-5: surge immunity test b IEC/EN 61000-4-6: immunity to conducted disturbances, induced by radiofrequency fields b CISPR 11: limits and methods of measurement of electromagnetic disturbance characteristics of industrial, scientific and medical (ISM) radiofrequency equipment b mandatory for CE marking: v EN 61000-6-2: immunity to industrial environments v EN 50081-1: emissions for commercial and residential environments b IEC/EN 60664-1: insulation coordination for equipment within low-voltage systems, part 1 b EN 50102: degrees of protection provided by electrical enclosures against external mechanical impact b IEC 60364 and NF C 15100: installation rules for low-voltage electrical distribution b UL 1053 and CSA 22.2 No. 144: relays RH10, RH21 and RH99 up to and including 220/240 V comply with these standards. Ground fault sensing and relaying equipment UL 1053 and CSA 22.2 No. 144 for North American and North American influenced markets The basic standard used to investigate products in this category is UL1053 "GroundFault Sensing and Relaying Equipment". The Listing Mark of Underwriters Laboratories Inc. on the products is the only method provided by UL to identify products manufactured under its Listing and Follow Up Service. The Listing Mark for these products includes the name and/or symbol of Underwriters Laboratories Inc. (as illustrated on the label) together with the word "LISTED", a control number and the following product name "Ground Fault Sensing and Relaying Equipment". This category covers ground fault current sensing devices, relaying equipment, or combinations of ground fault current sensing devices and relaying equipment which will operate to cause a disconnecting means to function at predetermined values of ground fault current in accordance with the National Electrical Code, ANSI/NFPA70. The RH99, RH21 and RH10 (M and P) ground fault relays are control powered ground-fault protection devices used to protect an electrical distribution system from ground faults. The relay receives input from sensors, processes the information and if necessary closes output contacts which will cause the associated protection device to trip. The product is a class 1 combination ground fault current sensor and relay. This equipment is intended to operate devices with shunt trip coils such as moulded case circuit breakers, moulded case switches and the like, which constitute the disconnecting means, by opening all ungrounded conductors at predetermined values of ground fault current. This product is designed to protect circuits of not more than 600 V AC, 50/60 Hz only. The relay should be marked with the following electrical ratings, for the two types M and P: b type M: DIN format (Multi 9 type fast mounting or screw mounting) b type P: front-panel mount (on panel, door, etc.) b ratings: v fixed I∆n threshold (a number of choices) and no time delay (instantaneous) or v selectable I∆n threshold from 0.03 to 30 A and user-selectable time delay from 0 to 4.5 s (see settings on pages 36 to 41) b input voltages: v AC: 20 to 24 V AC, 48 V AC, 110 to 130V AC or 220 to 240 V AC, 50/60 Hz, or v DC: 12 to 48 V DC b maximum consumption: 4 W. 19
