● Incomer: 100A DP main switch (isolator).
● Surge Protection: Type 2 SPD, 40 kA
● Pre‑fitted device: 1× MCB B32 (B‑curve, single‑pole)
● Ways: 10, 14, 18, 24 single‑row
● Enclosure: non‑combustible steel; SL versions with integrated door lock
● Terminal bars: Top‑mounted, color‑coded N and E.
This configuration delivers a ready‑to‑wire surge‑protected incomer with a pre‑installed B‑curve 32 A MCB. The integrated Type 2 SPD 40 kA safeguards downstream circuits against transient overvoltages, while the fitted B32 MCB saves assembly time and ensures a coordinated protection scheme from day one. The steel enclosure meets BS EN 61439‑3 and speeds up installation with top‑mounted color‑coded N/E bars, a removable DIN rail, backed‑out captive screws, and a support T‑bar. SL variants add an integrated door lock for secure access.
Q1: Can I replace the B32 MCB with another rating?
A1: Yes, the pre‑fitted B32 can be replaced by a suitably rated MCB as required by your design.
Q2: Does the pre‑fitted MCB reduce available ways?
A2: It occupies one outgoing way. See the free‑ways values in the spec table.
Q3: Is the SPD module replaceable?
A3: Yes. The Type 2 module includes a status window and can be replaced at end‑of‑life.
Q4: Are RCBOs supported on the remaining ways?
A4: Yes, the board accepts RCBOs and AFDDs downstream of the main switch.
