Schelinger A02-G7-3P-B16 Miniature Circuit Breaker 3P B 16A

The Schelinger A02-G7-3P-B16 is a high-quality 3-pole miniature circuit breaker engineered to provide robust protection for electrical circuits. Designed for both residential and commercial applications, this device reliably monitors power flow to prevent damage from overloads and short circuits. Its compact modular design allows for seamless integration into standard distribution boards, ensuring consistent performance and safety within modern electrical infrastructures.

Advantages

This miniature circuit breaker offers exceptional reliability and durability, making it an essential component for safeguarding electrical systems. The B-type tripping characteristic provides a balanced response to current surges, ensuring that the circuit remains protected without unnecessary nuisance tripping. Its 3-pole configuration allows for the simultaneous disconnection of three phases, which is critical for maintaining safety in three-phase power distribution networks. The robust construction ensures long-term operational stability even under demanding conditions.

Suitable for

• Residential electrical distribution boards
• Commercial office power systems
• Three-phase lighting and appliance circuits
• Small-scale industrial equipment protection

This device may not be suitable for applications requiring a different tripping curve, such as C or D types, which are necessary for circuits with high inrush currents like large motors or transformers. It is also not intended for use in environments exceeding its specified voltage or current ratings, nor should it be used as a primary isolation switch in high-voltage industrial main distribution panels.

Key specifications

• Number of poles: 3
• Rated current: 16A
• Tripping characteristic: B-type
• Mounting type: DIN rail
• Protection function: Overload and short-circuit protection

Installation should be performed by a qualified electrician in accordance with local electrical regulations. The device is designed to be mounted on a standard 35mm DIN rail within an enclosure. Ensure that all wire connections are tightened to the specified torque to prevent overheating and ensure optimal electrical contact. Before installation, verify that the power supply is disconnected and that the circuit breaker ratings match the requirements of the load being protected.

What to consider before purchase

• Verify that the 16A rating is appropriate for the connected load
• Ensure the B-type characteristic matches the startup current of your equipment
• Check available space in your distribution board for a 3-pole module
• Confirm compatibility with your existing DIN rail system

Usage recommendations: Regularly inspect the circuit breaker for signs of physical damage or discoloration. It is recommended to perform a functional test of the switching mechanism periodically to ensure it remains in good working order. Do not exceed the rated current capacity to avoid premature wear or failure of the internal components.
