Specification for TenderActi 9 RCCBs_spec_V1.doc

Residual Current Devices (RCDs):RCDs shall be of approved design and make and must be tested and validated as per respective IEC standards and shall carry CE marking.RCDs shall have IP 20 Degree of Protection shall be ensured to prevent electrical shocks by accidental touch to any live parts, by providing finger touch proof terminals.

Basic technical parameters, rating, operating voltage, etc. shall be printed on front face of RCDs for ease of identification. RCDs shall have clear indication of Tripping on fault on front facia.

RCDs must be voltage independent and purely current operated. For electrically disturbed networks, Super Immunised type RCDs shall be provided, which shall be immune to electrical impurities (viz. Harmonics, pulsated DC components, transient over-voltages) and Corrosive atmosphere (viz. humid environments, chemical gases, dust etc)Operating knob shall have provision to lock in ON / OFF condition without affecting any automatic tripping

The material used to manufacture RCDs shall be 100% recyclable and must comply to RoHS and REACH standards.

RCDs shall be suitable for field-fittable Protection auxiliaries (viz. Over-voltage release, Under-voltage release, Shunt trip) and Indication Auxiliaries (like Auxiliary Contact, Trip alarm contact).

The circuit breakers shall be communication ready to indicate the status of the device (On/Off/Trip), Number of On/Off cycles and Number of Tripping over universally open Modbus protocol, so as to have seamless connectivity with any Energy and Building Management System.Residual Current Circuit Breakers (RCCBs):

RCCBs must conform to IS12640 and IEC/EN 61008 standards.RCCBs shall be suitable for operation at 230V/415V, 50Hz supply. The RCCB ratings shall be available from 25A-125A in SPN and TPN versions with the sensitivity of 30mA (for personal protection) and 100/300mA (for Fire protection), as per the BOQ requirements. RCCBs shall carry ISI marking. The RCCB manufacturer (through the bidder) has to submit the valid BIS license certificate at the time of offer submission.

RCCBs shall have bi-connect facility to terminate fork type busbar and wires, simultaneously. Terminal capacity shall be minimum 25 sq.mm. for ratings up to 32A, and 35 sq.mm. for ratings above 32A, to ensure perfect termination of wires and cables. Terminals of RCCBs shall have captive screws. RCCB with Over Current Protection (RCBOs): 2 module versionRCBOs must confirm to IEC/EN 61009 standards.RCBOs shall be suitable for operation at 230V/415V, 50Hz supply. The RCBO ratings shall be available from 6A-40A in SPN version with the sensitivity of 30mA (for personal protection) and 300mA (for Fire protection), as per the BOQ requirements. RCCB with Over Current Protection (RCBOs): RCD Add on module versionRCD Add on module must confirm to IEC/EN 61009 standards.RCD Add on module, when integrated with MCB shall provide protection against Over load, Short Circuit and Earth Leakages

RCD Add on module shall be adaptable to mount MCB as per desired rating of the loads and wires to ensure precise protection to the installation

RCD Add on module shall be suitable for operation at 230V/415V, 50Hz supply. The RCD Add on module ratings shall be available till 125A in SPN, TP and TPN version with the sensitivity of 30mA (for personal protection) and 100/300mA (for Fire protection), as per the BOQ requirements.
