Product information

Description

The ABB S203-B63 miniature circuit breaker is a reliable electrical protection device designed to safeguard commercial and industrial electrical systems. Operating at a frequency of 50 to 60 Hz with a rated current of 63 A, this 3-pole circuit breaker provides effective defense against electrical overloads and short circuits. It features a type K trip curve and a breaking capacity of 6000 A, ensuring consistent performance in demanding environments. Built with dual tripping mechanisms, including a delayed thermal mechanism for overloads and an electromechanical mechanism for short circuits, it helps maintain overall electrical system integrity.

Advantages

This miniature circuit breaker offers high-performance current limitation and complies with international safety standards. Its compact 3-pole design integrates easily into standard distribution boards while maintaining efficient thermal and magnetic protection. The device accommodates bottom-fitting auxiliary contacts, which helps optimize panel space usage. Engineered for durability, it supports reliable operation across diverse industrial and commercial applications.

Suitable for

  • Industrial electrical installations
  • Commercial building power distribution
  • Overload and short-circuit protection in electrical circuits
  • Space-optimized control panels using auxiliary contacts

When it may not be suitable

This device is not designed for residential applications requiring standard consumer-grade protection curves, as it utilizes a specialized type K characteristic. It is also unsuitable for systems exceeding its specified rated current or breaking capacity limits.

Key specifications

  • Miniature circuit breaker
  • 3-pole configuration
  • Rated current: 63 A
  • Breaking capacity: 6000 A
  • Input frequency: 50 - 60 Hz
  • Total power loss: 14.4 W
  • Trip curve type: Type K
  • Width: 52.5 mm
  • Depth: 69 mm
  • Height: 88 mm
  • IP20 protection rating
  • Color: White

How to use

Installation should be performed by a qualified electrician in accordance with local electrical codes and standards. Mount the miniature circuit breaker onto a standard DIN rail within a compatible enclosure or distribution board. Ensure all electrical connections are securely tightened to the recommended torque specifications before restoring power to the circuit. Periodically inspect the installation for signs of wear or loose connections as part of routine maintenance.

What to consider before purchase

  • Verify that the 63 A rated current matches your electrical load requirements.
  • Ensure the type K trip curve is appropriate for your specific connected equipment.
  • Check available space in your distribution board for proper physical installation.
  • Confirm compliance with local electrical installation standards and regulations.

Usage recommendations

Always disconnect the main power supply before installing, servicing, or removing the circuit breaker. Ensure that the operating environment complies with the IP20 rating requirements and that total system loads do not exceed the specified technical limits.

International Protection (IP) code: The IP code classifies and rates the degree of protection provided against the intrusion (including body parts such as hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures. It is published by the International Electrotechnical Commission (IEC). The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X. an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. Another example is the Sony Xperia Z Ultra, one of the first cellular phones to be IP-rated; it is rated at IP58 and marketed as "dust resistant" and can be "immersed in 1.5 meter of freshwater for up to 30 minutes".
