Standard blocks: 1-24 poles Special arrangements: 25-52 poles Back-connected switch blocks

• A = Width of Switch Block overall, including Mounting Ears
• B = Distance between centers of Mounting Ear slots
• C = Width of Switch Block with Barriers (including Barriers automatically provided at each end of Switch Block, but not including Mounting Ears)
• D = Width of Cover
• E = Width of recommended panel cutout for Back-Connected Switch Blocks
• F = Length of Mounting Rod

• C without Cover = ( Number of poles * 5/8 ) + 1/16 [see Note]
• C with Cover or Back-Connected = ( Number of poles * 5/8 ) + 3/16 [see Note]
• A = C + 7/8 [and Add 1/8 inch if DIN Rail mounted]
• B = C + 7/16
• D = C + (1+1/16)
• E = C
• F = C + 9/16

Note - To allow for extra mounting support, for 26-50 poles add 5/8 inch to C; for 51 or more poles, add 1 ¼ inches to C.
