Product information

Description

The Siemens 5SY4101-7 circuit breaker is a reliable modular device designed for electrical installation protection in residential, commercial, and industrial buildings. Engineered by Siemens, this single-pole circuit breaker effectively safeguards electrical circuits against overloads and short circuits, ensuring continuous operational safety for connected equipment and wiring systems. With standard physical dimensions and a robust housing, it integrates seamlessly into standard distribution boards and consumer units.

Advantages

This circuit breaker offers dependable fault protection with a precise 1 A rated current specification, making it ideal for low-current circuits requiring sensitive safeguarding. It operates efficiently at a standard 50 Hz input frequency and supports a rated voltage of up to 400 V. The IP20 protection rating ensures safe indoor installation within enclosed electrical distribution enclosures, preventing accidental finger contact with live parts. Its standardized modular design facilitates quick mounting on standard DIN rails within electrical panels.

Suitable for

  • Securing low-current electrical circuits in residential properties
  • Protecting specialized control and signaling circuits in commercial buildings
  • Safeguarding sensitive electrical equipment against overloads and short circuits
  • Installation within standard modular distribution boards and consumer units

When it may not be suitable

This device is not designed for outdoor installation without an appropriate weather-resistant weatherproof enclosure, as it features an IP20 rating which lacks protection against moisture and dust. Additionally, with a rated current of 1 A, it is strictly intended for low-current applications and is unsuitable for protecting heavy-duty household or industrial appliances with higher electrical current requirements.

Key specifications

  • Rated current: 1 A
  • Rated voltage: 400 V
  • Input frequency: 50 Hz
  • Protection rating: IP20
  • Package dimensions: 21 mm width, 93 mm depth, 83 mm height

How to use

The circuit breaker must be installed exclusively by a qualified electrician in compliance with local electrical safety regulations and wiring codes. It is designed to be mounted onto a standard DIN rail inside an appropriate electrical distribution enclosure or consumer unit. Ensure that the electrical supply is completely switched off before attempting any installation, wiring, or maintenance work. Connect the incoming and outgoing supply wires securely to the designated terminals, verifying that all screw connections are properly tightened to prevent loose contact and potential overheating during operation.

What to consider before purchase

  • Verify that the 1 A rated current matches the specific electrical load requirements of your circuit
  • Check that your distribution board has sufficient physical space, noting the device width of 21 mm
  • Ensure the installation environment meets the IP20 rating requirements by placing the unit inside a suitable enclosure
  • Confirm compatibility with standard 400 V voltage systems and 50 Hz input frequency
Usage recommendations: Regularly inspect the electrical distribution board for any signs of wear, loose connections, or dust accumulation. Test the operational readiness of the circuit protection devices periodically in accordance with professional electrical maintenance guidelines. Never exceed the specified rated current of 1 A to avoid nuisance tripping or potential damage to the connected electrical circuit.

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".
