5. Robust & Secure: Housed in a BS EN 61439-3 steel enclosure with an optional integrated lock ("SL" models).

Use Cases:
1. High-end new builds and premium renovations.
2. Properties with extensive electronic systems, home automation, or EV chargers.
3. Installations where maximizing safety, compliance, and reliability is the top priority.

FAQs:
Q1: Does the SPD protect all circuits?
A1: Yes, the SPD is installed at the incoming stage to provide surge protection for the entire board, including circuits on both RCDs.

Q2: Why is the B32 MCB included?
A2: It provides the required overcurrent protection for the SPD module, ensuring it operates safely and is compliant with wiring regulations.

Q3: How many free ways are left for my circuits?
A3: An 18-way model provides 10 free ways, split across the two RCDs (2x6 busbar pins, with 2 ways used per RCD).

Q4: Is this board difficult to wire?
A4: No, because all the main components are pre-fitted and pre-wired, installation is faster and simpler than building a similar setup from individual parts.

Q5: Is a lockable version available?
A5: Yes, select the "SL" variant for an integrated door lock.
