Schneider iC60N 3P 16A C Curve MCB 6kA

Schneider iC60N 3P C16 Miniature Circuit Breaker

Product Introduction

The Schneider Electric iC60N is a compact miniature circuit breaker built for three-phase electrical distribution in commercial and industrial installations. This 3P device pairs thermal-magnetic protection with a C curve response, so it handles circuits with moderate inrush currents. Additionally, the iC60N 3P C16 provides a 6 kA breaking capacity under IEC 60898-1 and higher ratings under IEC 60947-2 at 400 V AC.

Electrical Specifications

The iC60N 3P C16 works with a rated current of 16 A and a magnetic trip threshold of 8×In ± 20%. Furthermore, its thermal-magnetic trip unit reacts to both overload and short-circuit events. The rated operational voltage reaches 400 V AC for three-phase applications. Meanwhile, the service breaking capacity ensures stable performance under fault conditions.

For coordination purposes, this iC60N breaker supports cascading with upstream devices. Specifically, correct selection of upstream protection lets the iC60N 3P C16 achieve enhanced short-circuit withstand ratings. Therefore, system designers can optimize protection schemes without oversizing downstream components.

Mechanical and Environmental Parameters

This miniature circuit breaker features a compact form factor of 82 mm × 54 mm × 78.5 mm. Besides, the device weighs approximately 0.3 kg, which simplifies handling during installation. The operating temperature range spans -35°C to +70°C, supporting demanding environments.

Moreover, the iC60N offers robust mechanical endurance of 20,000 cycles and electrical durability of 10,000 cycles. Additionally, the product complies with both EN/IEC 60898-1 and EN/IEC 60947-2 standards. Its 35 mm DIN rail mounting design fits standard distribution boards.

Installation Guide

First, ensure the power supply is fully disconnected before starting installation. Next, snap the iC60N 3P C16 onto a standard 35 mm DIN rail. The device accepts rigid cables from 1 to 25 mm² and flexible conductors from 1 to 16 mm². For instance, tighten terminal screws to the specified torque to guarantee secure connections.

Additionally, the breaker supports top or bottom connection orientation. Combined busbar compatibility allows for efficient multi-pole installation. However, always verify phase sequencing when wiring three-phase loads.
