ABB 2CDS253001R0607

The S203-K63 is a three-pole miniature circuit breaker (MCB) that offers overload and short circuit protection through its dual tripping mechanisms: a delayed thermal mechanism and an electromechanical mechanism. It is rated for a current of 63 A and is compliant with standards such as IEC/EN 60898-1 and IEC/EN 60947-2, making it suitable for a range of residential, commercial, and industrial applications.

This model supports a rated operational voltage of up to 440 V AC and features a breaking capacity of 6 kA at 400 V AC. Its compact design allows for space-saving with the option to mount auxiliary contacts. The installation on a DIN rail is facilitated by its compatibility with TH35-15 and TH35-7.5 standards, and it can be positioned in any orientation.

With an operating temperature range of -25 ... +55 °C and a storage temperature of -40 ... +70 °C, this circuit breaker is designed to withstand harsh environments. The device is also characterized by its high resistance to mechanical and electrical endurance, rated for 10,000 AC cycles and 20,000 mechanical cycles.

The environmental impact of the S203-K63 is mitigated through its recyclability rate of 80.7%, in line with the EN45555 standard, and its compliance with RoHS and REACH directives ensures it meets current environmental regulations.
