Schneider A9F89332 Output module

Schneider Electric iC60N C32A 3P Overview

The Schneider Electric iC60N A9F89332 is a three-pole (3P) Miniature Circuit Breaker (MCB) with a rated current of 32A and a C-curve tripping characteristic. It is part of the iC60 range, designed to provide overcurrent and short-circuit protection for low-voltage electrical installations in residential, commercial, and industrial buildings.

Product Detailed Description

• Function:

• Overcurrent Protection: Automatically interrupts the circuit when the current exceeds the rated value, preventing damage to equipment and the risk of fire.

• Short-Circuit Protection: Quickly interrupts the circuit in the event of a short-circuit fault, minimizing damage to electrical equipment and the risk of personal injury.

• Isolation Function: Provides electrical isolation, ensuring the downstream circuit is safely de-energized during maintenance or troubleshooting.

• Features:

• iC60 Range: Belongs to Schneider Electric's iC60 series, known for its high performance, reliability, and safety.

• C-Curve Tripping Characteristic: Designed to protect circuits with moderate inrush currents, such as lighting, socket outlets, and some small motors. The C-curve allows for short-duration overloads (e.g., motor starting) but reacts quickly to sustained overloads and short-circuit faults.

• 3 Poles (3P): Provides protection for all three phases of a three-phase circuit.

• Rated Current 32A: Indicates the maximum current the circuit breaker can carry continuously without tripping.

• Rated Breaking Capacity (Icu): Indicates the maximum short-circuit current the circuit breaker can interrupt without being damaged and while being able to continue operating safely. Refer to the parameters section for the specific value.

• Rated Service Breaking Capacity (Ics): Indicates the circuit breaker's ability to interrupt a short-circuit current and then immediately be able to reclose and continue operating at its rated voltage. Ics is usually a percentage of Icu.

• Standards Compliance: Complies with relevant international and domestic standards such as IEC 60898-1.

• Visual Trip Indication: Provides a clear indication of whether the circuit breaker is ON, OFF, or tripped.

• Lockable Accessories: Optional accessories allow the circuit breaker to be locked in the OFF position for safety during maintenance.

• Environmentally Friendly: Complies with environmental regulations such as RoHS and REACH.

Precautions

• Correct Selection: Choose the appropriate circuit breaker model and tripping characteristic based on the circuit's rated current, expected load characteristics, and installation requirements. The C-curve is suitable for applications with moderate inrush currents.

• Correct Installation: Follow Schneider Electric's installation guidelines, ensuring the circuit breaker is securely mounted, correctly wired, and using appropriate tools.

• Coordination with Overload Protection: For comprehensive protection, appropriate cable sizes and upstream protection devices (e.g., fuses or higher-level circuit breakers) should be selected based on the specific application.

• Regular Inspection: It is recommended to periodically inspect the circuit breaker's operating condition, ensuring there are no signs of damage or overheating.

• Safe Operation: Always follow relevant electrical safety regulations when performing any electrical installation or maintenance work, ensuring the circuit breaker is in the OFF position.

• Avoid Overloading: Do not exceed the circuit breaker's rated current. Continuous overloading can cause premature failure or prevent the circuit breaker from providing effective protection.
