Introduction
When a 20A final circuit needs dependable short-circuit protection, the Schneider iC60H 2P C20 miniature circuit breaker delivers. Part of the Acti9 iC60 range, this two-pole device combines thermal-magnetic protection with a 10 kA breaking capacity at 230/400V. It suits industrial control panels, commercial distribution boards, and OEM machinery where downtime is expensive.
Key Parameters at a Glance
Current and Trip Behaviour
The 20A rated current matches common lighting and power sub-circuits. Its C-curve trips magnetically at 8×In ±20%, so it tolerates brief inrush from motors and transformers without nuisance tripping. Thermal protection handles sustained overloads.
Breaking Capacity and Voltage
With 10 kA breaking capacity at 230/400V under IEC 60898-1, the device clears high fault currents safely. It also carries a 125V DC rating, useful for DC control and auxiliary circuits.
Physical and Service Life
The breaker measures 85 × 36 × 78.5 mm and weighs 0.25 kg. It mounts on standard 35 mm DIN rail. Mechanical life reaches 20,000 cycles; electrical life reaches 10,000 cycles.
Replacement and Upgrade Guide
Why Replace Aging Breakers
An old breaker may still close, yet its trip curve can drift after years of service. Replacing it with the iC60H 2P C20 restores predictable protection. The Acti9 iC60 series remains active in production, so spare units stay available.
Matching the Existing Installation
Check three items before ordering: pole count (2P), rated current (20A), and trip curve (C). Also confirm the busbar and terminal layout fit your panel. The 36 mm width leaves room in tight enclosures.
Upgrade Path from Older Devices
If your panel uses an obsolete two-pole 20A breaker, this unit offers a direct DIN-rail replacement. Its 10 kA rating may exceed the old device, which raises the panel’s short-circuit withstand. Verify upstream protection coordination after fitting.
Installation Notes
Mount the breaker on a 35 mm DIN rail inside a suitable enclosure. Follow local wiring rules and the manufacturer’s instructions. Keep the operating temperature within -35 to 70 °C. Do not modify the device or open its case.
Maintenance and Reliability
Inspect terminals periodically for tightness and heat marks. Exercise the handle during routine checks to confirm free movement. In dusty or humid plants, include the breaker in scheduled panel inspections. Because electrical life is 10,000 cycles, track switching operations in high-use circuits and plan replacement before the limit.
Compatibility and Integration
This breaker follows EN/IEC 60898-1 and EN/IEC 60947-2. It fits standard 35 mm DIN rail and works alongside other Acti9 iC60 devices in distribution boards. The 125V DC rating supports DC control circuits where applicable.
Selection Checklist
Before you buy, confirm the rated current, poles, curve, and voltage match your circuit. Check panel space against the 85 × 36 × 78.5 mm dimensions. For bulk or urgent needs, SpareTechPLC supplies this model with fast turnaround.
