FAQs
What does '1P+N' mean?
It signifies that the circuit breaker protects one live (phase) pole and the neutral pole simultaneously. This is common in some electrical systems for complete isolation.
What is the purpose of the 'Type C' trip curve?
A Type C curve is designed to handle higher inrush currents from inductive loads (like motors or transformers) without tripping. It's less sensitive to short, high current surges than Type B but more sensitive than Type D.
Can I use this breaker outdoors?
No, the iC40N has an IP20 rating, meaning it is not protected against water. It should only be used in dry, indoor environments or within a suitable enclosure.
What is the breaking capacity?
The breaking capacity is 6000 Amperes (A) according to IEC 60898-1. This is the maximum fault current the breaker can safely interrupt.
How do I clean the circuit breaker?
Ensure the power is off. Use a dry, lint-free cloth to wipe the exterior. Avoid using liquids or solvents, as they can damage the components.
What is the operating temperature range?
The circuit breaker can operate reliably in ambient temperatures ranging from -25 °C to 70 °C.
What is the width of this breaker?
The width is 18 mm, which is standard for a single-pole plus neutral breaker on a DIN rail.
Troubleshooting
Breaker trips immediately upon reset
This indicates a short circuit. Disconnect all loads on the circuit and attempt to reset. If it still trips, there is a fault in the wiring or a connected appliance. Contact a qualified electrician.
Breaker trips intermittently under normal load
Check if the connected load exceeds the 6A rating. The circuit may be experiencing temporary overloads. Consider reducing the load or upgrading to a higher-rated breaker if the load is permanently higher (consult an electrician).
Breaker will not stay engaged
Ensure the mounting clip on the DIN rail is secure. If the breaker itself appears damaged, it may need replacement.
Pros and Cons
Pros
- Reliable protection against overloads and short-circuits.
- Compact 1P+N design saves space in electrical panels.
- Type C curve is ideal for circuits with potential inrush currents.
- Durable construction suitable for a wide temperature range.
- Meets multiple international safety standards.
Cons
- Limited breaking capacity of 6000A may not be sufficient for very high fault current environments.
- IP20 rating means it's not suitable for wet or dusty conditions without additional enclosure.
- Standard width (18mm) requires compatible breaker slots.
Setup, Compatibility & Care
Setup: The iC40N is designed for DIN rail mounting. Ensure the power is completely disconnected before installation. It connects via screw terminals designed for appropriate wire gauges. Refer to the installation diagram provided with the product or consult a qualified electrician for correct wiring.
Compatibility: This breaker is compatible with standard DIN mounting panels and requires a panel with space for its 18mm width. It operates on a rated voltage of 230V and frequency of 50/60 Hz.
Care: Keep the breaker clean and free from dust and moisture. Ensure adequate ventilation around the breaker in the electrical panel. Periodic inspection by a qualified electrician is recommended to ensure continued safe operation. Do not attempt to service or repair the breaker yourself; if it trips frequently or shows signs of damage, it should be replaced.
