Schenker | MCB, 80-125A, 10kA D Curve, 1-4 Pole

The Schenker SM10-125-D is a high-current miniature circuit breaker with a 10kA breaking capacity and D curve trip characteristic, for main circuit and heavy-load protection where currents above the standard 13mm MCB range (63A) are required. It suits electricians, installers and contractors wiring main distribution boards, larger motor circuits, and commercial or light industrial installations using the Schenker mini rail system.

• Application: Main circuit and high-current load protection, motor and transformer circuits
• Key specification: 10kA breaking capacity, D curve, 80A-125A
• Poles: 1, 2, 3 and 4 pole versions
• Voltage rating: 240/415VAC, 50/60Hz
• Identification: Orange toggle (D curve)

Key Features

• SABS approved, in accordance with IEC 60947-2 and VC8036
• 10kA breaking capacity, suited to main distribution circuits with higher prospective fault current
• D curve trip characteristic tolerates high inrush currents from motors and transformers without nuisance tripping
• 80A, 100A and 125A ratings cover main incomer and heavy circuit protection above the standard 13mm MCB range
• Available in 1, 2, 3 and 4 pole configurations to match single-phase or three-phase supply

Typical Applications

• Main incomer/circuit protection on distribution boards
• Large motor and pump circuit protection
• Transformer primary protection
• Commercial and light industrial installations

What's Included

• 1 x Schenker SM10-125-D MCB (amperage and pole count per variant selected)

Please note: Mini rail, distribution board, busbar and wiring accessories are not included unless specifically listed above.

Installation & Compatibility Notes

• Confirm this high-current, high-kA breaker is correctly specified for your main circuit or load — main incomer and heavy circuit protection should be confirmed against your board's fault level and supply capacity.
• Confirm D curve is appropriate for the connected load; D curve suits motors, transformers and other high inrush-current equipment.
• Confirm the correct pole count (1P/2P/3P/4P) for your supply configuration.
• Installation should be carried out by a suitably qualified electrician.
