Selective overcurrent circuit breaker ETIMAT SM 1p E16 002129200

Selective overcurrent circuit breaker ETI ETIMAT SM 1P E16 – reliable installation protection

The ETI ETIMAT SM 1P E16 overcurrent circuit breaker is an electrical protection element designed to protect circuits against overloads and short circuits. The device is characterized by selectivity, which means that in the event of a short circuit, it will only disconnect the damaged section of the installation, minimizing the scope of power outage. This is particularly important in complex electrical installations where precise operation of protection devices is crucial.

Construction and functionality

The circuit breaker is designed for mounting on a DIN rail, ensuring quick and easy installation in electrical distribution boards. Its compact size (1 module) allows for optimal use of space in switchgear cabinets. The "E" tripping characteristic makes the circuit breaker perform well with impulse and shock loads typical of devices with induction motors or transformers. The rated current of 16A makes it an ideal choice for protecting circuits with medium power consumption.

• Selectivity: Ensures disconnection of only the damaged circuit, minimizing disruption to the operation of the remaining parts of the installation.

• DIN rail mounting: Enables quick and easy installation and replacement.

• Characteristic E: Suitable for loads with shock and impulse currents (e.g. motors, transformers).

• Possibility of sealing: Lever in "On" and "Off" position – additional protection against unauthorized operation.

• Contact position indicator: Facilitates visual control of the circuit breaker status.

• ON/OFF marking: Clear marking on the switching lever makes operation easier.

• Rated switching capacity 25kA: Guarantees effective short-circuit interruption even at high currents.

Application and compliance with standards

The ETI ETIMAT SM 1P E16 circuit breaker finds application in a wide range of electrical installations – both in residential, commercial and industrial buildings. It will be useful for protecting lighting, electrical outlets, and devices with moderate power consumption. The device meets safety requirements, providing reliable protection of the installation and users. The degree of protection IP20 protects against contact with live parts and against the ingress of solid objects larger than 12.5 mm. Designed to operate at a rated voltage of 400V and a frequency of 50Hz. Overvoltage category IV and pollution degree 3 indicate the possibility of use in environments with increased requirements regarding resistance to interference.
