Porduct Overview

This double-row EKDB16S(L) board offers a high-capacity split load solution. It combines a 100A main switch with a single 80A RCD, dedicating one full row to RCD-protected circuits (ideal for sockets and high-risk areas) and the other row to circuits needing only overcurrent protection (fed from the main switch). This design is perfect for large, mixed-use installations where many circuits of different types are required. The spacious BS EN 61439-3 compliant steel enclosure simplifies complex wiring jobs.

Key Advantages:
1. High-Capacity Split Load: Provides a large number of ways clearly separated into RCD and non-RCD groups.
2. Organized Layout: Dedicating one row per protection type simplifies installation, commissioning, and fault-finding.
3. Flexible Application: Ideal for mixing RCBOs on the main switch row with MCBs on the RCD row.
4. Spacious Enclosure: Ample room for wiring, even with full-capacity installations.
5. Robust & Compliant: Steel enclosure meets BS EN 61439-3; optional lock on SL models.

Use Cases:
1. Large properties needing to separate critical circuits (e.g., smoke alarms, security systems) from general-purpose circuits.
2. Light commercial installations with a mix of lighting and power requirements.

FAQs:
Q1: How are the ways divided?
A1: One row is fed directly from the main switch, and the second row is fed from the 80A RCD. The 28-way model offers 12 free ways per row, and the 36-way offers 16 per row.

Q2: Can I protect the whole board with RCDs?
A2: This model is designed for a split. For full RCD protection, consider an all-RCBO installation on the double-row main switch board, or the double-row dual RCD model.

Q3: Can I add an SPD?
A3: Yes, an SPD kit can be fitted on the main switch-fed row.

Q4: What is the RCD rating?
A4: The board includes one double-pole 80A, 30mA Type A RCD.

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