Schenker | 13mm MCB, 6kA D Curve, 1-3 Pole

The Schenker SM13C6-D is a 13mm module width miniature circuit breaker (MCB) with a 6kA breaking capacity and D curve trip characteristic, identifiable by its orange toggle. D curve breakers trip at a higher instantaneous current than C curve, making them suited to circuits with high inrush currents such as motors, transformers and some pump loads. It suits electricians and installers wiring domestic, commercial and light industrial distribution boards using the 13mm Schenker mini rail system.

• Application: Circuit protection for high inrush-current loads (motors, transformers, pumps)
• Key specification: 6kA breaking capacity, D curve, 13mm module width
• Ratings: 6A to 63A across 1, 2 and 3 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
• D curve trip characteristic tolerates higher inrush currents than C curve without nuisance tripping, suited to motor and transformer circuits
• 6kA breaking capacity for installations with higher prospective fault current
• Orange toggle for quick visual identification against standard C curve breakers
• 13mm module width, compatible with the Schenker SM13 mini rail system and SCU distribution boards

Typical Applications

• Motor and pump circuit protection where high starting/inrush current would nuisance-trip a C curve breaker
• Transformer primary circuit protection
• Commercial and light industrial distribution boards

Technical Specifications

What's Included

• 1 x Schenker SM13C6-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 D curve is the correct trip characteristic for your load — D curve is intended for high inrush-current equipment (motors, pumps, transformers), not general lighting/socket circuits, where C curve is usually correct.
• Confirm the correct amperage rating for your circuit load and cable size before ordering.
• Confirm this is the correct pole count (1P/2P/3P) for your supply configuration.
• Installation should be carried out by a suitably qualified electrician.

Warranty & Support

This product is supplied with the applicable manufacturer or supplier warranty, subject to correct installation, correct application, and warranty terms.
