* Unless otherwise stated, all bolted neutral terminations G2, H2 are the same as phase terminations G1, H1. 'R' dimension represents the maximum width across mechanism spring guides. 'T' dimension = additional height of connecting barrier. First auxiliary pack adds 24.5mm to side of the switch when attached; each additional auxiliary pack adds a further 10.5mm.

Internal Enclosure Dimensions
These enclosure dimensions are for guidance only as recommended minimum inside enclosure dimensions, for temperature rise considerations.

Note: Larger dimensions may be necessary for the bending and termination of cables, copper, etc..
