Siemens 5SL6216-6 Miniature Circuit Breaker, 2-Pole, B-Characteristic, 16A, 6kA

The Siemens 5SL6216-6 is a professional-grade 2-pole miniature circuit breaker engineered to provide robust protection for electrical circuits in residential and commercial environments. This device is designed to detect and interrupt overcurrents, effectively preventing damage to wiring and connected equipment caused by overloads or short circuits. With its precise B-characteristic curve and reliable switching mechanism, it serves as a critical component for maintaining safety and operational stability in modern electrical distribution systems.

Advantages

This circuit breaker offers exceptional reliability and durability, reflecting the high manufacturing standards associated with Siemens electrical components. Its 2-pole configuration allows for the simultaneous disconnection of both phase and neutral conductors, enhancing safety during maintenance or fault conditions. The B-characteristic ensures rapid response to short circuits while accommodating standard inrush currents typical of household appliances and lighting circuits, making it a versatile choice for various installation requirements.

Suitable for

• Residential electrical distribution boards
• Commercial office lighting and power circuits
• Protection of standard household appliances
• General-purpose electrical installations requiring 16A capacity

This device may not be suitable for industrial applications involving high-starting-current motors or heavy machinery that require C or D-characteristic breakers to prevent nuisance tripping. It is also not intended for use in DC circuits unless specifically rated for such applications, as it is optimized for standard AC electrical systems.

Key specifications

• Number of poles: 2
• Rated current: 16A
• Tripping characteristic: B
• Breaking capacity: 6kA
• Mounting type: DIN rail

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The device is designed for snap-on mounting onto a standard DIN rail within a distribution enclosure. Ensure that the supply voltage is disconnected before beginning the installation process and verify that all terminal connections are tightened to the specified torque to prevent overheating.

What to consider before purchase

• Verify that the 16A rating matches the load requirements of your circuit
• Ensure the B-characteristic is appropriate for your specific equipment
• Check available space in your distribution board for a 2-pole module
• Confirm compatibility with your existing DIN rail system

For optimal performance and safety, regularly inspect the circuit breaker for signs of physical damage or discoloration and ensure that the surrounding environment remains free of excessive moisture or dust.
