WYLEX PSB Series
WYLEX PSB Series
WYLEX PSB Series MCBs, RCBOs & associated RCDs.
Current range of WYLEX BSEN60898 MCBs for commercial use (NH boards). Fits onto TPN busbar fixed teeth.
Common in many commercial distribution board setups, differ from WYLEX NHX MCBs in that they do not have the cutout around the front screw onto the busbar.
Do not use or attempt to force NHX breakers onto the NH Type A or Type B boards. The cutout around the front screw can allow the busbar teeth to arc out across the gap under certain circumstances. Due to these issues we recommend that ONLY WYLEX PSB series MCBs or RCBOs are ever fitted to WYLEX NH boards.

PSB MCB Dimensions (Type B, C & D 1P)
Both B, C & D type Wylex PSB MCBs share the same dimensions as each other.
All MCBs & RCBOs share the same single module (1P) width
The height (top to bottom) is: 89mm

Alternative Fitments?
The WYLEX PSB series of circuit breakers & RCBOs use the same toothed busbar and share a similar busbar connection layout as the following:
- WYLEX NSB Series MCBs & RCBOs – DO NOT FIT DESPITE SIMILAR APPEARANCE
- WYLEX NHX Series MCBs & RCBOs – DO NOT FIT DESPITE SIMILAR APPEARANCE
NB: WYLEX NSB or NHX MCBs are NOT a swap for WYLEX PSB MCBs despite the similarities. DO NOT FIT NHX or NSB MCBs to a TPN board
