GARO DTPN36 11 Way 3 Phase Distribution Board – 125A Main Switch and Type 2 SPD
The GARO DTPN36 11 Way 3 Phase Distribution Board is a surface-mounted GARO TPN distribution board for 230/400V installations. This larger enclosure provides eleven usable three-pole outgoing positions after accommodating the SPD protection MCB. Although GARO specifies 12 nominal three-phase ways (36 single-phase ways), the factory-fitted MCB protecting the Type 2 SPD occupies one complete three-phase way. That leaves 11 usable three-phase ways, equivalent to 33 single-phase module positions for outgoing protection. A 125A four-pole main switch is fitted as standard. The GARO DTPN36 11 Way 3 Phase Distribution Board offers a practical solution for installations requiring multiple outgoing circuits and integrated surge protection.
Key Features – GARO DTPN36 11 Way 3 Phase Distribution Board
- Usable three-phase capacity: 11 outgoing ways after the SPD protective MCB.
- Nominal capacity: 12 three-phase ways / 36 single-phase ways before the SPD MCB deduction.
- Remaining single-phase module equivalents: 33 (actual circuit count depends on selected devices).
- SPD protection: factory-fitted Type 2 surge protection with its protective MCB already installed.
- Main switch: 125A four-pole, factory fitted.
- Installation: surface-mounted steel distribution enclosure, IP20 / IK05.
- Dimensions: 460mm wide × 891mm high × 130mm deep.
- Outgoing device options: suitable GARO MCBs, RCBOs or AFDDs selected to the circuit design.
- Main switch upgrade: compatible with optional 250A four-pole main switch upgrade kit (not included).
How Many Ways Are Available?
The GARO DTPN36 11 Way 3 Phase Distribution Board has a nominal capacity of 12 three-phase ways (36 single-phase ways). However, the included SPD protective MCB occupies the space of one three-pole outgoing device. As supplied, the available space for additional circuits is therefore 11 three-phase ways (33 single-phase module equivalents). Check the module widths of your selected MCBs, RCBOs and AFDDs when planning the layout.
