Hager ADM432T 32A 4 Pole RCBO Safety Switch 3P+N 6kA C Curve 30mA Type A 230-415V AC 4 Module DIN Rail

Description

32A three-phase protection with 30mA personal safety.

Rated at 32A, the Hager ADM432T is a 3P+N RCBO that handles overload, short-circuit and earth leakage duties in a single 4 module device. It suits higher-current three-phase final subcircuits where each circuit needs its own residual current protection rather than sharing a group RCD.

Key Features

• Rating: 32A, curve C
• Leakage protection: 30mA Type A
• Poles: 3P+N, four poles protected
• 6kA short-circuit capacity (Icn = Ics, IEC 60898-1)
• Supply: 230-415V AC, 50Hz
• 4 modules wide (71mm), 84mm tall, 70mm deep
• Top screw terminal and bottom biconnect terminal
• 360° mounting, right-hand neutral
• IP2X, I²t energy limitation class 3

Where the ADM432T Fits in a Three-Phase Board

MCB and RCD functions combined
Hager describes the ADM432T as combining MCB and RCD functions to protect three-phase circuits. The overcurrent element guards cabling against overloads and short-circuits up to 6kA, while the 30mA Type A residual current element provides personal protection against earth leakage. Hager positions it for residential and commercial switchboards.

Curve C at 32A
Hager specifies curve C for mixed loads. This tripping characteristic allows short switch-on surges without tripping, while still clearing genuine faults. The Type A residual current element responds to both AC and pulsating DC leakage currents. Insulation is rated at 500V, with a 4kV impulse withstand voltage and overvoltage category 3.

Thermal and wiring considerations at 32A

• Current carrying capacity drops with ambient heat: 32A at 30°C, 30.3A at 40°C, 28.5A at 50°C and 26.5A at 60°C.
• Where two devices sit side by side, Hager gives a 0.80 correction factor.
• At rated current the device dissipates 14.6W, worth allowing for in enclosure heat calculations.
• Screw terminals accept 1-16mm² flexible or 1-25mm² solid cable at 2Nm.
• Hager lists an operating range of -25 to 40°C and a maximum installation altitude of 2000m.
• To be fitted by a licensed electrician, compliant with AS/NZS 3000.

Q: Is the Hager ADM432T suitable for a three-phase circuit?
A: Yes. Hager states the ADM432T protects three-phase circuits, with a rated operational voltage of 230-415V AC and four protected poles (3P+N).

Q: What breaking capacity does the Hager ADM432T have?
A: Both its rated short-circuit breaking capacity (Icn) and service breaking capacity (Ics) are 6kA, according to IEC 60898-1.

Q: How many operations is the Hager ADM432T rated for?
A: Hager rates it at 2,000 electrical cycles and 4,000 mechanical operations.
