Lewden RCBO-20/30/SPA 1 Module Single Pole B Curve Type A RCBO 20A 6kA 30mA

Single module RCBOs are suitable for use in TN-S,TN-C-S, & TT * network systems. (* when used in conjunction with a 2 pole mains isolation switch). Note that alone, single pole RCBOs are not considered as a suitable means of isolation on systems with IT & TT earthing arrangements, where it may be necessary to disconnect the neutral connection in order to achieve safe isolation of individual circuits.

RCCB / RCBO OPTIONS
Lewden RCCBs and RCBOs are available in both type AC and type A versions, offering the installer the option to choose the correct protection device for the load application. The range also includes 100A rated RCCBs in type A, in 30mA and 100mA time delayed versions.

Protection against overcurrent
RCCBs do not provide protection against overload or short circuits. They must be used in conjunction with MCB devices to provide circuit protection against overloads and short circuit faults.

Power supply polarity
Lewden type A & AC RCCBs are not polarity sensitive. The devices can be mains fed from either the upper or lower terminal sets. On 2 pole devices, Line and Neutral connections can be transposed to either to the left or right (e.g. Line IN/OUT can be made on either pole 1-2 or 3-4) On 4 pole devices, Line and Neutral connections must be strictly terminated according to the terminal markings on the device. 4P devices are suitable for use in circuits with and without a neutral supply connection (3 and 4 wire systems), due to the integral test circuit being connected between two of the phases.

Earth system
RCCBs are suitable for use in TN-S,TN-C-S, & TT network systems. Where used within a split load consumer unit installed in domestic premises forming part of a TT network, the double pole main switch of the consumer unit should incorporate an S type time delayed RCCB, e.g. 100mA S type RCCB
