Siemens 5SL6116-6 Miniature Circuit Breaker, 1-Pole, B-Characteristic, 16A, 6kA

The Siemens 5SL6116-6 is a professional-grade 1-pole miniature circuit breaker engineered to provide dependable protection for electrical circuits. Designed to safeguard residential and commercial installations, this device monitors current flow to prevent damage from overloads and short circuits. With its robust construction and precise B-characteristic tripping curve, it offers a reliable solution for maintaining the integrity and safety of your electrical distribution system.

Advantages

This circuit breaker stands out due to its high manufacturing standards and consistent performance under various load conditions. The B-characteristic curve makes it particularly effective for protecting circuits with low inrush currents, such as lighting and general-purpose outlets. Its compact 1-pole design allows for efficient space utilization within distribution boards, while the 6kA breaking capacity ensures that the device can safely interrupt fault currents, providing essential protection for connected wiring and appliances.

Suitable for

• Residential lighting circuits
• General-purpose power outlets
• Small commercial electrical installations
• Protection of resistive loads

This device may not be suitable for circuits with high inrush currents, such as those powering large electric motors, transformers, or heavy-duty industrial machinery, where a C or D characteristic breaker would be required to prevent nuisance tripping.

Key specifications

• Number of poles: 1
• Rated current: 16A
• Tripping characteristic: B
• Breaking capacity: 6kA
• Mounting type: DIN rail

To install the circuit breaker, ensure the main power supply is disconnected. The device is designed for standard DIN rail mounting within an electrical distribution board. Secure the breaker firmly onto the rail and connect the incoming supply cable to the top terminal and the outgoing load cable to the bottom terminal. Ensure all connections are tightened to the manufacturer's specified torque to prevent overheating.

What to consider before purchase

• Verify that the 16A rating matches the requirements of your circuit wiring.
• Ensure the B-characteristic is appropriate for the type of load being protected.
• Check the available space in your distribution board for a 1-pole module.
• Confirm that the 6kA breaking capacity meets local electrical safety standards.

Usage recommendations: Always consult with a qualified electrician for installation to ensure compliance with local electrical codes and safety regulations. Periodically inspect the device for signs of thermal damage or loose connections to maintain optimal system performance.
