c The minimum enclosure depth is greater than Dimension D since additional space is needed when mounting the mechanism. d Fuses and fuse base assembly do not extend beyond bracket. Back panel support is recommended for Types TFB1, 2, & 3. Other devices may also require support if flange is not sufficiently rigid.
