SCHNEIDER IEC

Schneider Electric is a global manufacturer of electrical distribution and industrial control equipment, with a product portfolio that includes circuit protection, power management, and automation components. The company's IEC product line encompasses modular devices designed to meet International Electrotechnical Commission standards, which are widely adopted in industrial and commercial electrical systems outside North America. Within this line, the C60SP series of supplementary protectors provides overcurrent and short-circuit protection for branch circuits and equipment. These devices are UL1077-recognized, meaning they are suitable for use as supplementary protectors in applications where branch circuit protection is already provided. The C60SP series is available in various configurations, including the D-curve, 2-pole models that 3G Electric supplies. D-curve trip characteristics are designed to accommodate high inrush currents, making them appropriate for loads such as motors, transformers, and power supplies. The protectors feature screw clamp terminals for secure wire connections and are mounted on standard DIN rail, facilitating installation in control panels and distribution boards. Voltage ratings for the 2-pole versions include 240/415/440 V AC, and interrupting capacities range from 10 kA to 14 kA at 240 V AC, depending on the current rating. Current ratings span from 1 A to 40 A in the models listed, covering a broad spectrum of low-power control circuits to higher-power branch circuits. 3G Electric stocks a selection of Schneider IEC supplementary protectors, specifically the D-curve, 2-pole UL1077 DIN rail-mount models from the C60SP series. These products are available for global shipment, supporting maintenance, repair, and operations (MRO) as well as original equipment manufacturer (OEM) requirements. The supplementary protectors are used in industrial control panels, HVAC equipment, lighting systems, and other applications where reliable overcurrent protection is needed. 3G Electric provides access to these components with documentation and support to help buyers select the appropriate rating and configuration for their specific electrical requirements.

Frequently asked questions

Common questions about SCHNEIDER IEC from 3G Electric.

What is the difference between a supplementary protector and a circuit breaker?

Supplementary protectors, such as the Schneider IEC C60SP series, are UL1077-recognized devices intended to provide overcurrent protection for equipment and branch circuits where branch circuit protection is already provided by a listed circuit breaker or fuse. They are not a substitute for branch circuit protection and do not provide the same level of protection as a UL489 circuit breaker. Supplementary protectors are typically used for additional protection of sensitive loads, control circuits, or specific equipment.

What does the D-curve trip characteristic mean on Schneider IEC supplementary protectors?

The D-curve trip characteristic is designed to handle high inrush currents, such as those generated by motors, transformers, and power supplies. It allows the protector to ride through brief current spikes without tripping, while still providing overcurrent protection. This makes D-curve devices suitable for applications where standard B or C curve devices might nuisance trip. The C60SP series offers D-curve options in various current ratings.

What are the voltage and interrupting capacity ratings for the Schneider IEC C60SP 2-pole supplementary protectors?

The 2-pole C60SP supplementary protectors are rated for 240/415/440 V AC. Interrupting capacity varies by current rating: most models in the 1 A to 25 A range have a 14 kA interrupting capacity at 240 V AC, while the 40 A model has a 10 kA interrupting capacity at 240 V AC. These ratings indicate the maximum short-circuit current the device can safely interrupt.

Can Schneider IEC supplementary protectors be used in industrial control panels?

Yes, Schneider IEC supplementary protectors are commonly used in industrial control panels for overcurrent protection of control circuits, PLCs, and other sensitive equipment. Their DIN rail-mount design allows for easy installation alongside other modular devices. The D-curve models are particularly useful for circuits with high inrush currents, such as those with motors or transformers. They are UL1077-recognized, making them suitable for supplementary protection within panels.

What is the difference between the 1 A and 40 A Schneider IEC supplementary protectors?

The primary difference is the current rating: the 1 A model (M9F23201) is designed for very low-power circuits, while the 40 A model (M9F23240) handles higher currents. Both are 2-pole, D-curve, UL1077 DIN rail-mount devices with screw clamp terminals. The 1 A model has a 14 kA interrupting capacity at 240 V AC, whereas the 40 A model has a 10 kA interrupting capacity. Selection depends on the load requirements and coordination with upstream protection.
