Overcurrent circuit breaker S 312 2P B 16A 10000A TX3 404112

Protection of the installation and safety of use

The S 312 2P B 16A circuit breaker is a reliable device that protects the electrical installation from the effects of overloads and short circuits. Its task is to quickly disconnect the power supply in the event of a dangerous situation, minimizing the risk of damage and fires. This ensures safety for both the installation and the people using it.

Construction and application

This two-pole circuit breaker, with a rated current of 16A, is used in electrical circuits requiring protection with characteristic B. This means that the circuit breaker reacts quickly to sudden current increases, but is also resistant to short-term surges associated with the starting of electrical appliances. It is ideal for protecting lighting, electrical outlets or semi-permanent circuits. Installation is done on a TH35 rail, which simplifies and speeds up installation. Compatibility with auxiliary equipment (auxiliary contacts, releases) allows for expanding functionality and adapting to individual needs.

Key features and benefits

• High short-circuit breaking capacity: 10 kA at 400V and 16 kA at 230V guarantees effective protection even in the event of serious short circuits.
• Characteristic B: Provides a quick response to overloads and short circuits, while allowing the starting of devices with motors without unnecessary tripping of the circuit breaker.
• Flush mounting: Allows for aesthetic integration of the circuit breaker into the existing installation.
• Width of 2 modules: Compact dimensions allow for saving space in the switchboard.
• Protection class IP20: Provides protection against accidental contact and against the ingress of solid objects into the device.
• Compliance with standards: Meets the requirements of EN 60898-1 and EN 60947-2 standards, which confirms its safety and reliability.
• Expandability: Compatible with a wide range of DX³ series accessories, allowing adaptation to specific installation needs.
• Rated voltage 400V AC: Designed to operate in standard electrical installations.
