GARO DTPN48 15 Way 3 Phase Distribution Board
The GARO DTPN48 15 Way 3 Phase Distribution Board supports compatible outgoing MCBs, RCBOs and AFDDs, allowing electricians to configure circuit protection according to the installation requirements. The factory-fitted protective MCB is dedicated to the Type 2 SPD and cannot be used for an additional outgoing circuit.
Key Features – GARO DTPN48 15 Way 3 Phase Distribution Board
- Usable three-phase capacity: 15 outgoing ways after allowing for the SPD protective MCB.
- Nominal capacity: 16 three-phase ways / 48 single-phase ways.
- Single-phase module equivalents: 45 remaining positions, depending on the widths of outgoing devices.
- Surge protection: factory-fitted Type 2 SPD with dedicated protective MCB.
- Main switch: 125A four-pole switch fitted as standard.
- Enclosure: surface-mounted steel construction, rated IP20 and IK05.
- Dimensions: 460mm wide × 999mm high × 130mm deep.
- Outgoing protection: compatible GARO MCBs, RCBOs and AFDDs can be selected separately.
- Upgrade option: compatible with GARO’s optional 250A four-pole main switch upgrade kit (not included).
How Many Ways Are Available?
The GARO DTPN48 15 Way 3 Phase Distribution Board has a nominal capacity of 16 three-phase ways (48 single-phase ways). However, the factory-fitted MCB protecting the Type 2 SPD occupies one complete three-phase way.
This leaves 15 usable three-phase ways (45 single-phase module equivalents) for additional outgoing circuits. The actual circuit count depends on the number of poles and module widths of the selected MCBs, RCBOs and AFDDs.
