Motor protection switch, electric motors overload current (thermal current), short -circuit current, protection against the phase error, as well as the electric motor manually activated and disabled electrical control, control and protection element.

Sigma motor protection switches are produced with thermal adjustment in the range of 0.1A to 80A, with short circuit capacity of up to 100ka and provide convenience in applications with wide accessories. Motor protection switches are selected according to the power of the engine, the engine nominal current value and the working voltage.

Motor protection switches, thermal and magnetic troops, act as a circuit breaker and protect the motor system against extreme currents. Providing fast character opening and providing protection against phase loss creates the difference between thermal magnetic protection elements such as circuit-automatic insurance.

Another circuit element used in the protection of motor systems in the industry is the thermal relay-contiger combination.

Sigma motor protection switches provide space for space with a single product and offer an optimum solution of compact dimensions.

with extremely wide accessory opportunity,

Remote opening can be provided with open coils.

The low voltage coil and the network voltage fall below a certain value.

Auxiliary contacts can be informed whether the engine protection switch is in the circuit.

The preservation box is prevented from physical damage to the motor protection switch, while the IP55 protection class can be provided against dust and moisture.

Remote control of the engine circuit with the contactor combination block is provided.

Why Sigma Motor Protection switch should be used?

Sigma motor protection switches are produced in accordance with TS EN and European standards with their compact dimensions and reliable working performance. With a cutting capacity of up to 100ka, it safely protects engine circuits and electrical installation without using a protective circuit element, while providing more economical solutions on the panels. Thanks to the adjustable thermal current range, it creates optimum solution for various applications. In case of any overcurrent in the system, it cuts the circuit very quickly and prevents the damage of the engines.
