Schneider Contactors and Protection Relays

A power contactor is an electrical device used to turn an electrical circuit on and off. It's a multi-pole switch, which means it can control numerous power circuits with a single contactor. Regarded as a unique kind of relay, the main difference between the contractors and the relay is that the contactor relay is utilized in applications that require a larger current carrying capacity, whereas the relay is used in conditions that require a lower current carrying capacity.
Importance of Power Contractor Relays
It goes without saying that motor protection relays are vital cogs of any machinery system. They perform the important task of safeguarding the motor from burnout caused by overload. Schneider Electric's flagship line of contractors, TeSys provides top-quality performance along with a notable mechanical and electric life. Buyers even have the choice of purchasing an extensive range of accessories for motor & load control.
The TeSys Contactors can be bought with either of the IEC and NEMA applications and follows the global standardization grades. When a relay is utilised in order to switch a significant amount of electrical power through its contacts, it is designated a specific name: contactor relay. Contactors generally consist of multiple contacts, and those contacts in most cases normally-open, in order to guarantee that power to the load is shut off when the coil is in the de-energized state. Probably the most popular industrial use for Schneider Electric India’s contactors is in the regulation of electric motors.
Applications of Power Contactor Relays
In simple terms, contactor relays are electrically operated switches deployed for effectively controlling electric circuits. There are several types of contactor relays like 4-pole contactors, vacuum contactors, AC contactors, DC contactors, etc that are deployed in a variety of applications like automation circuits, protection circuits, control circuits, and more.

Motor protection circuit-breakers

In order to ensure that all the industrial processes are running smoothly and efficiently, devices like motor starters and circuit breakers are critical. Motor circuit breakers are devices that integrate low voltage circuit breakers as well as thermal overload relays functions and facilitate the protection of motor branch circuits against overloads, phase-loss and short-circuit, besides enabling secured wiring.

Thermal Overload Relays

Schneider Electric India has held a prestigious reputation for designing reliable and quality electrical products and solutions for different sectors of society. Explore a flexible and adaptable range of thermal overload relays designed for TeSys D, K and F contactor ranges.

One of the best features of thermal overload relays is that they can be mounted directly under contactor relays for compactness, separately using accessories and can be used as a stand-alone solution or mounted directly onto miniature contactors for advanced motor protection. Some of the many ranges we offer under this category are TeSys Deca Thermal Overload Relays, TeSys LR9- LR9D/LR9D, etc.

Electronic Over Current Relays

Electronic overcurrent relays provide protection against the locked rotor and mechanical shocks. Unlike the thermal overload relays, these contactor relays do not have a thermal memory; instead, they have definite time characteristics with adjustable current threshold and time delay.

At Schneider Electric India, we have laboriously designed an array of highly robust and reliable electronic overcurrent relays that carry ranges like TeSys Deca electronic relays, TeSys Deca overcurrent relays, TeSys LT3, and more.

Motor switch-disconnectors and fuses

At Schneider Electric India, we have a team of professionals who carry comprehensive knowledge in the electrical field in order to design high-quality products and solutions to meet all your electrical needs and requirements.

In addition, with contactor relays, we also offer high-performance motor switch-disconnectors and fuses that are imperative to prevent hazardous situations like fire breakout, explosions, short circuits, and more. Some of the many products ranges that we carry under this category are TeSys GS, GB2, TeSys mini-vario, etc.

Motor starter combinations

chneider Electric India holds a reputation for providing highly reliable and efficient electrical solutions across different sectors of society. From contactor relays to fuses and circuit breakers, we ensure that all our products are easy to install, affordable, and flexible in nature.

Our expert professionals have designed a variety of motor starting combinations like DOL starters, automatic motor starters, thermal magnetic motor circuit breakers, safety switch disconnectors, and more. TeSys GV2-ME, TeSys LE DOL starters, TeSys GV2, LC are some of the many product ranges we offer under motor starter combination.
