Easy motor starting solutions
1st Quarter 2018, Electrical switching & drive systems & components


New to Magnet’s range of Schneider low voltage motor starting solutions are EasyPact TVS motor starters, designed for motor control and protection for simple applications. The new E range – an extension of the current range – includes contactors, thermal overload relays, control relays and motor circuit breakers, all designed and precision engineered to give OEMs and panel builders a motor starter solution that offers high performance and safety at a competitive price.

“This range ensures compatibility and easy installation in new or existing motor control panels,” explains Brian Howarth, managing director of the Magnet Group. “Direct mounting of the thermal overload underneath the contactor minimises cabling and installation time, also enhancing reliability of the system and saving panel space. This all contributes towards cost saving.” An important feature of the system is that it has been designed for application optimisation, which means users are able to select only what components are needed for each specific project. A clear reference system ensures easy product selection for every application and because fewer components are required, design is simplified and stocking requirements are reduced.

The EasyPact TVS range encompasses nine sizes of contactors that cover a broad range of current ratings (6 to 630 A). These are used in conjunction with thermal overload relays from 0,1 to 630 A, industrial control relays with 4 NO/NC contacts, and a newly designed motor circuit breaker from 0,1 to 32 A.

Utilisation categories are Class AC-1 for loads with cos φ at least equal to 0,95 (resistive load, heating and distribution) and AC-3 for squirrel cage induction motors, with contactor breaking taking place with the motor running. Thermal overload relays protect a.c. circuits and motors against overloads, phase failures, long starting times and prolonged stalled rotor conditions. The thermal relay controls the current driven by the motor and if this current exceeds the setting, the auxiliary contacts will change state, causing the motor to stop.

Thermal-magnetic 3-pole protection motor circuit breakers are designed for connection by screw clamp terminals to ensure a secure, permanent and durable clamping that is resistant to harsh environments, vibration and impact. Magnetic elements for short circuit protection of the motor have a non-adjustable tripping threshold, which is equal to about 13 times the maximum setting current of thermal trips. Thermal elements for overload protection include automatic compensation for ambient temperature variations. For protection to personnel, all live parts are safeguarded against direct finger contact to IP20.

The EasyPact TVS range ensures co-ordination between protection and control components, which means there is a safe and fast restart after a short circuit. To ensure suitable protection of electrical components against fire, product damage or power loss, Magnet recommends installation of this system in a spacious CRN steel enclosure. Severe conditions, including dust, humidity and high temperatures, can expose personnel and equipment to serious risks.

The EasyPact TVS motor starter system, which is suitable for simple applications, including HVAC, lighting in buildings, cooling or extraction fans, small pump and mixer applications, manufacturing and conveyor belts, conforms to stringent international quality, safety and environmental specifications. Magnet offers a technical advisory support service throughout the country.
