Overcurrent circuit breaker, 1P+N, B characteristic, 16A, 10kA, AC | S201M-B16NA 2CDS271103R0165

Overcurrent circuit breakers for installation protection

This overcurrent circuit breaker, with B characteristic and a rated current of 16A, is a reliable protective element in every electrical installation. Designed to protect circuits against overload and short circuit, it ensures safe operation and longer life of connected devices. The 1P+N construction (single pole with switchable neutral) makes it ideal for protecting individual lighting or socket circuits.

Functionality and application

This circuit breaker, thanks to its B characteristic, is perfect for circuits with devices with high inrush current – such as motors or transformers. The B characteristic means that the circuit breaker reacts quickly to short-circuit currents, but tolerates short-term current surges during device start-up. The rated short-circuit breaking capacity of 10kA (at 230V) and 15kA (at 400V) guarantees effective disconnection of the circuit in the event of a failure. Mounting on a DIN rail is quick and intuitive for both professional installers and people performing electrical work independently.

Key features and benefits

• Overload and short-circuit protection: Protects the electrical installation and connected devices from damage caused by excessive load or short circuit.
• B characteristic: Ideal for circuits with devices with high inrush current, minimizes the risk of unnecessary tripping of the circuit breaker during normal operation.
• Short-circuit breaking capacity: High short-circuit breaking capacity (10kA/230V, 15kA/400V) ensures effective disconnection of the circuit in the event of a failure.
• DIN rail mounting: Allows for quick and easy mounting in the distribution board.
• 2 module width: Compact dimensions allow for efficient use of space in the distribution board.
• Wire cross-section: Accepts solid wires with a cross-section of 0.75-35 mm² and stranded wires 0.75-25 mm², ensuring compatibility with various types of installations.
• Protection degree IP20: Provides basic protection against accidental contact.
• Operating temperature: Wide operating temperature range (-25°C to +55°C) allows use in various environmental conditions.
• Rated insulation voltage Ui: 440V - guarantees safety in standard electrical installations.
